Downwind Choices

Cruising sailboats are often sighted traveling dead downwind.   The crew will poll out a single headsail, launch the chute or have twin headsails.  Typically the main is not hoisted.  The boat then steers dead downwind, but, is this efficient?  Gail says, “Who cares? It is comfortable and easy to maintain.”

Let us look at the hard numbers.

Choice A:

Sail dead downwind for 1 hour at 5 knots.   The next sunny anchorage is dead down wind so this is the most direct course.

Choice B:

Sail on a deep reach at a true wind angle of 140 degrees to the wind.  This allows for increased apparent wind and a bit of the slot effect to power the boat to increased speeds. The speed through the water will increase, but will it compensate for the increased distance one needs to sail?   If you travel at 6.52 knots for a half-hour and then jibe to the same wind angle on the other tack, you will arrive at your anchorage at the same time.   You need to travel at least 30% faster!   From experience in light to moderate air, this is achievable.   In stronger breezes, I tend to go dead downwind, since the boat is going fast enough for my taste.   However, the 140 degree true wind angle has another benefit.  When puffs come, the crew can head down to de-power the boat, an option unavailable to the dead downwind boat.     The boat’s polars would also indicate the best idea is to avoid dead downwind.

So what is the best angle?   I find anything deeper than a 140 degree true wind angle (i.e. 145, or more) causes the main to blanket the head sail too much.  If hand steering, I will flirt with 145 in the puffs and heat the boat up to 130 in the lulls.  If I have the boat on autopilot wind mode, then I target 140.  135 feels great but you are sailing 41% more nautical miles than the dead downwind course.

Of course, speed is great but comfort is key.  Sometimes the jibing angles can be less comfortable due to the seas.  Or sometimes the crew is not up for jibing every 3 hours.

How did I get these cool numbers?  My clever wife used her geometry and cosine skills. Our Furuno navigation system displays VMC(velocity made course) or VMG(velocity made good). I find these not be as useful because they rely on the paddle wheel and get fooled by a slightly off-angle waypoint. On some jibes you look like you have made a great decision, while on other jibes you look as if you are sailing in reverse.   It is easier to just use the ratios.  Play with your sails to find your best ratio beating set up.

Brazilian Customs, Border Patrol and Police

Clearing in and out of Brazil takes time. Consider this post your seeing eye dog for a Brazilian paper pushing adventure.   Embrace the process of being lost, being told conflicting instructions by different parts of the government, and traveling through the non-tourist parts of Brazil.   Once I had the right attitude, I enjoyed living like a Brazilian –  life is always ok in América do Sul.

THE KEY PLAYERS

109px-Coat_of_arms_of_the_Brazilian_Federal_Police.svg

 

Polícia Federal:  This branch of the government is like the FBI and border patrol merged into one.  No joking with the Polícia Federal because their day job is fighting violent criminals.   The Polícia were firm, but always professional.  They stamp your passport and check your visa. They are focused on proper border entry, gun possession, time in the country, and whether your yacht is a stolen vessel.   If you stay past 90 days, they can extend your time in Brazil.  They are more concerned with the people than with the yacht.   I approach all entry agencies holding the passports of the entire crew and acting as agent for the crew.   This makes it much easier to appear organized for the Policia.   At the end of process, the Polícia will ask to see the crew.

Capitania dos Portos

Capitania dos Portos

 

Capitania dos Portos (Marinha do Brasil):  The Port Captain is the Brazilian Coast Guard and is part of the Brazilian Navy.  It is good to have their emergency number programmed into your satellite phone.  They are the only department you visit that goes to sea.  We were never boarded, however, we did see two boats being boarded by the Marinha do Brasil while we were in the north.  They expect ALL visitors to be dressed properly in long pants, shoes (not flip flops) and a collared shirt.   This is good policy for all the Brazilian offices and expect to be turned away if  you don’t comply.  I always enjoyed visiting their offices, since they were often stationed inside a major working port.   These offices tended to have the longest lines, but the staff were very friendly.

Receita Federal

Receita Federal

Receita Federal:  The Receita Federal is the Brazilian IRS and Customs Department.  The Receita are not interested in your safety, rather your wallet.   Brazil has a 100% boat importation tax and unscrupulous Brazilians try to avoid the tax by flying a US ensign.  The Receita’s job is to encourage the tax cheats to rethink their decision and pay the mandatory tax.  At our first Brazilian landfall, we had to meet the taxman an excruciating four times.   They were concerned that Two Fish was a sailing charter business because she is owned by an LLC.   Receita agents insisted on boarding the yacht which I think was driven by curiosity after seeing the yacht’s assessed value.   The agents boarded with black soled shoes and asked to see our ship’s log.  The collection of 4 meetings went from 9am to 7pm.    I found these folks to be buffoons and bullies.  So they have something in common with the US revenue service?   Good news is you only need to see them twice (entry and departure from the country).     Warning: they want to know your last port in Brazil.  The best port to use is Fortaleza since this is the farthest northern town a Yacht would enter and gives you more flexibility in departure.

Papers you need

1)  Passports of all crew with Brazilian Visas

2) Certificate of Documentation (Department of Homeland Security – US Coast Guard):  I always furnished a color copy and was never asked for the original.

3) If your boat is owned by an LLC, then papers that show you are allowed to control this boat.   I talked about this in a previous post.

4)  Initial entry documents from Uruguay will only be needed for your first port of call.

Papers I had but never showed

1)  Insurance

2)  US radio license

3)  ASA sailing certificates

4)  Marriage and birth certificates

5)  Vaccination cards from our doctors

Process

First landfall in Brazil

1) Polícia Federal:   They will stamp your passport and inspect your visa.  Your passport will not be stamped again till departing the country but will be inspected in every state.  The Polícia Federal will give you a “Passe de Entrada” de embarcação  (Entry pass for a ship).   Do not throw out the “Passe de Entrada” as you will need to return it  to the nice fellow who just gave it to you when you check out of this port.   You will always have either a Entrada or Saída when in Brazil.  This will prove you are either checked in or checked out.  We have a notebook where we keep of all of the ship’s papers and we bring this on our official visits to reduce the chance of forgetting a document.   We do scan many of our key documents and store them on the cloud.   Also, we sometimes only furnish a copy to protect the original.

There are many Polícia Federal in larger cities, so ask other boaters or the marina and they might send you in the correct direction.  In most northern cities the marina will ask you to travel by cab or face certain death.  To compare this to an airport, after the Polícia visit, you have made it passed border patrol and can go to the luggage carousel but you are not really in the country.

2)  Capitania dos Portos:   The port captain will ask you to fill out a 2 page form with odd questions such as your engine’s horsepower and whether the boat has a VHF.   This  is another do not lose document.  It will be checked for the entire Brazil trip and not swapped like the Passe de Entrada.   The Port Captains across the country create a memento for you, by stamping and signing this at every port you check into.  Think of this document more like a passport for the boat.   Some Port Captains have AIS, so make sure your story at the office matches your arrival time in that remote bay.

 

3)  Receita Federal:  After being water boarded by the Receita they will give you a one page document, the TECAT (Termo de concessao de admission temporaria).  The TECAT will need to be shown many times in the future.  The document gives you the right to enter your yacht without paying tax because you are transiting and not staying or running a business.   Keep it close to your Coast Guard documentation as it is a favorite of the paper pushers.   You will only visit the Receita at your first and last port in Brazil.

 

TECAT - Temp Importation

TECAT – Temp Importation

Exiting a state but staying in Brazil

1) Polícia Federal:  Hand back your  “Passe de Entrada” and get a “Passe de Saída”.   Show Polícia but keep passports, TECAT, and Port Captain documents.

2)  Capitania dos Portos:  Another stamp for your collection on the “Declaracao de Entrada/Saída.   They will also ask to see the Passe de Saída that you just received from the Polícia.

Entering a state but already cleared into Brazil

1) Polícia Federal:  Hand back your “Passe de Saída” and get a new “Passe de Entrada”.   Show Polícia but keep passports, TECAT, and Port Captain documents.

2)  Capitania dos Portos:  Another stamp for your collection on the “Declaracao de Entrada/Saída.   They will also ask to see the Passe de Entrada.

Leaving Brazil

1) Polícia Federal:  Imagine that now you are flying out of the airport.  They will give you an exit stamp in your passport and your final Declaracao de Saída.   If you expect your stay to be longer than 90 days, then this office may offer you an extension.

2)  Capitania dos Portos:  Your final stamp – they will let you keep the memento of your trip.

3)  Receita Federal:  Despite threats from the taxman, Two Fish was not confiscated or taxed 100%.   The Receita will also give you a exit document.  I would keep this if I planned to return to Brazil.

When to check-in

US vessels are supposed to check in and then out every time they sail into a new Brazilian state.   We did not follow the rules 100%.   We skipped checking in while in remote locations, on very short stays and on non-business days.   We also typically checked in a day after arriving in a new state.   Forgiveness for late check in was easy to find but permission was impossible.   The dream bureaucratic maneuver was the combination check in and check out.  Like a unicorn it is written about but rarely seen because this shortcut is  reserved for yachts that arrive in the morning and leave in the afternoon.   A few times we got a pet unicorn for stays longer than 2 days.

 

Brazilian State Did we stop? Check in?
Rio Grande do Sul Yes Port of Entry (3 agencies)
Santa Catarina Two stops No
Parana No
Sao Paolo No
Rio de Janeiro Four stops Once
Espirito de Santos Yes No (only stopped at offshore island)
Bahia Two stops Checked in at second stop
Sergipe No
Alagoas No
Pernambuco Two stops Checked in at second stop
Paraiba Yes No
Rio Grande do Norte No
Ceara Yes Yes

 

TOP SHORTCUTS

1)  Check in Check out on the same day (disused earlier)

2) Website  (www.edbv.receita.fazenda.gov.br)  This just started when we arrived so we filled out the form online but in the Receita offices.

3)  Finding the offices:   Do not ask for immigration or customs or any similar American places.   They will not make sense to Brazilians with decent English.  Instead use the proper Portuguese names that I have included in the post.

4)  When you arrive at the offices use the term “Entrada or Saída par un embarcacao veleiro”.

5)  Do not have your entire crew come to the desk, just the captain.

 

With the right attitude you can enjoy these trips.  We did.

Passage Plan

When we lived onshore, we never planned our day trips. While the elevator whisked us down to street level, we decided whether to travel via foot, subway, or, taxi.  On the boat, we have a formal pre-passage process including a crew briefing, weather forecasts and routing.  For a day sail our planning can be somewhat brief, but when we are leaving for 1,000 miles, more preparation is required.   The wind, tides, marina hours, sunsets, currents and crew schedules all create a complex timing puzzle with no ideal answer but a series of trades-off based on estimates.

Sample passage plan: The passage plan is either handwritten in my journal or stored in an excel spreadsheet; it is a summary of the important considerations for each leg of the passage. For me, writing down the plan reinforces it in my mind. In a tight spot, quickly knowing the weather trend, bail-out port and major navigational hazards is key.   The crew may be seasick and the captain might not have a chance to reread the source materials.

SAMPLE PRE-PASSAGE NOTES:

Portland Light

Portland Light

Leave Portland, Maine to Point Judith, Rhode Island (160 nautical miles) Sunrise :  615am    Sunset: 7:05pm Moonrise:   10pm  Moonset: 9am  (half moon) Portland Tide:  10 am low water,  7am 1.2 knots ebb, 9am 1.4 knots ebb Cape Cod Canal Tide:   3am (slack tide)  5am 3.5 knots west 9 am (tide going east) Pt Judith Tide:  Plenty of depth and tide up to 1.5 knots.   OK to arrive anytime before 11am. *Tides are described in the direction they are going while winds are described in the direction the are coming from.   In Florida, the Gulf Stream is a northerly ocean current (warm water traveling up the east coast).   If the breeze is from the North, a northerly, then the current and wind will be in opposition directions and sailors should expect large waves.   When we transit areas of strong tides or currents, we try to avoid such oppositions.   The strongest spots we traversed this summer were Hells Gate in NY, Cape Cod Canal, and The Race at the end of Long Island Sound.  All three locations can experience more than 4 knots of tidal speed.

Timing of arrival

We have not even weighed anchor, and I am thinking of our arrival time?   Our departure time is influenced by the time we wish to arrive at our destination, ride a current, or, pass a particular hazard.  Most of the time I try arrive in advance of a timing window, because it is easier to slow the boat down than to speed it up.    To speed the boat up,  you can put up more sail area and risk ruining a nice sail or worse, or, you can run your motors at high RPMs.   We tried to make it to a Brazilian offshore island before sunset on our trip north.   We were motor sailing and I increased the RPMs with the hope of making the anchorage before susnet.  The bad decision was driven by the “magic 8 ball”.   The magic 8 ball is my nickname for  Furuno’s predicted arrival time.   The number gyrates up and down as Two Fish pushes through waves.   The optimist sees the 7pm arrival, but the realist knows it is not possible.  In the Brazil island case, the breeze and seas became unfavorable, causing us to get progressively slower.  We arrived at 2am and burned so much fuel, we had to add an additional stop for diesel.   Lesson learned – have a fuel plan.   A conservative rule of thumb is 1 gallon per hour of run time per engine at 2,200 rpm.  The fuel gauges, while not perfect, offer a hint of our current fuel load.   On major passages we have carried an additional 35 gallons in jerry cans, but while coastal cruising, we carry only 15 gallons.

Trying to slow the boat but Guiana current will not oblige

Trying to slow the boat but Guiana current will not oblige

Slowing the boat down is the alternative to speeding up for a deadline.  It is used frequently by sailors and employees of the Department of Motor Vehicles.     Reducing sail area can allow precision with arrival times but sometimes the boat will not slow down.   In a 3 knot current off French Guyana and also in a 23 knot aft breeze off the Jersey Shore we were forced to hove-to as the final technique to  slow the boat down.   In both cases the boat kept going 2-3 knots;  it was good we hoved-to early else we would have overshot our destination, resulting in a brutal upwind or up-current passage to get back to the harbor in the morning.

  Next Port of Call

As part of our destination selection process we read cruising guides, charts and Active Captain (like Yelp for boaters).   Some cruising guides are very marina focused so it is good to speak with locals as well.  This post is already too long so I will postpone a review of our massive collection of cruising guides.  On a similar vein, pilot charts show the average wind speed and direction for large bodies of water by month.  We have not found pilot charts very useful. Once we have chosen the place we are sailing towards, it is worth also noting bail out ports. For example, here are the harbors of refuge I had for the trip from Ft. Lauderdale to NYC: St. Augustine, Savannah, Charleston, Morehead City, Norfolk, and Cape May.   The longest stretch we had without a harbor of refuge was in Northern Brazil during our transit of the Amazonian river basin.  The river pushes massive volumes of water against the prevailing trade winds; this creates short steep waves as you get closer to shore.   If you did bash your way upstream the ports lack most services for boat repair.  Better to duct tape whatever is broken and fix it in Trinidad.

 

Weather Routing service

Ocean temps and black routing line

Ocean temps and black routing line

Of course it is not enough to just know your destination. Our speed, comfort and safety are governed by the weather and we are constantly checking the forecasts. For long passages, we like to get advice from the experts on when to leave, what to expect along the way and recommended waypoints. We are fans of Commander’s Weather and used them on all trips longer than 600 miles.  We felt that paying a few bucks to have a pro give you a green light was a worthwhile investment.   They can also send you mid-passage updates for passages longer than a few days. Forecasters are not able to prevent sailing into a few squalls, but they can help you avoid a tempest.   Here are my Florida to NY passage notes that Commanders Weather prepared for Two Fish.    I felt much better having such a thorough write up before undertaking the passage.  On the day of departure they prepared a more thorough write up of the expected conditions. We also used Jennifer Clark’s weather service.  Her specialty is the Gulf Stream and has guided many sailors racing from Newport to Bermuda.    Her suggested route and Commanders’s route were about the same.   The third route produced by me using the NOAA data had similar recommended waypoints. Weather Forecast by Two Fish Most weather apps and websites are based on the GRIB (Gridded Binary Data) files that come from NOAA.  The model is named GFS (Global Forecast System) and feeds zillions of different websites.   Do not get lost on the internet searching for new forecasts because they may be the GFS with some pretty colors.  We get our GRIBS by downloading them via our KVH sat phone while at sea.  The GRIB is a data file and you need a viewer to look at them. I use ZyGrib but could use MaxSea or dozens of free programs and apps. Most of the viewers have a GRIB request function that helps you define the area and fetch the data.   ZyGrib is free for the Mac and PC.  Download the version which has more cities as it is easier to find your position.  After surveying the predicted weather for my upcoming passage I start filling in the details.   I create the route on my iPad in the Navionics app.   I make a speed assumption of about 6 knots to estimate where Two Fish will be every 3 hours.  This is so I can obtain the weather forecast for my approximate position throughout the trip.  This process could be done with a few key strokes in Max Sea, however, I prefer the more manual approach since I spend more time familiarizing myself with the data.  More looks at the charts and more time with the weather files gives me more time to ponder different scenarios and how I will respond.   If the wind shifts more than expected and I have 25 knots on the nose, where will I seek shelter? This video is an introduction to using ZyGrib.  I have no connection with the authors of the software.  I just like it.

Sidebar on speed estimation: I have found the polars for the Antares do not match Two Fish realized boat speeds.

Speed estimate is key for East River transit

Speed estimate is key for East River transit

We have been frequently traveling with just two people so we tend to be under canvassed when we exceed 9 knots of boat speed. On the other hand, we travel faster than the polars when the air is light or have a head wind, since we engage the engine. Cruiser polars should include adjustments for motoring. Instead, I use the crude estimate that we average about 6 knots in the light winds of Long Island and 8 knots in the trade winds before adjusting for current. When motoring we only run one engine at 2,200 or fewer revs. Some day I will create an amazing program that takes into account how cruisers actually sail but until then I will use my 3 hour estimates and skip the routing software in MaxSea.

  More Detail on Weather Plan Before leaving the dock, I combine my estimated positions for every 3 hours of the journey with the GRIB information to produce the below table, reminding myself that zyGrib GRIBS  are based on UTC. Gail only looks at the Gusts column because she believes the GFS gust data is a better predictor of the wind we will encounter. Our course for this example is 230 degrees and is used to calculate True Wind Angle (the difference between your course and the true wind direction). True Wind Angle is a key factor – 20 knots on the bow can be uncomfortable while 30 knots from the stern can be comfortable.  To get wave data using zyGrib, you must click on the wave tab when choosing data for download. Waves are not estimated for near-coastal areas.

Position Time UTC Wind Speed (knots) Gusts True Wind Direction True Wind Angle Waves (meters)
Near Portland Light 0600 1000 8-10 15 090 60 1m
Prout’s Neck 0900 1300 14-16 21 120 100 1
Kennebunkport 1200 1600 5-7 11 90 130 .5

We also look at the CAPE data in zyGrib; this is the probability of convective activity, a chance for thunderstorms.   Give this a look when sailing in Florida or the doldrums.   It is best if you can avoid the high risk areas, but if you are stuck then make sure you are using your radar in dual range mode.   In dual range mode half the screen is set to see 3 miles to avoid other boats.   The other half of the screen is set to see 24 miles for rain clouds.   On the 24 mile screen turn the rain clutter to zero and gain very high so rain clouds show up.   Now you can try to use your radar to avoid the worst storm clouds.

What can you learn from the table?

Full main or a reef?

Full main or a reef?

Waves:   Waves on the nose over 2 meters with a short period are hellish and the fun factor goes away over 1 meter.   A following sea with a decent period can be comfortable up to 5 meters.   Waves are nasty when an ocean current and a breeze are passing in opposite directions. Wind speed:   The Antares can handle wind very easily when it is aft of 90 degrees.   If there are gusts up to 30 at less than a 90 degree true wind angle, then you better make sure you have enough ginger on board. Wind shifts:   Cruising may not be racing, but cruisers like to be comfortable and looking for shifts can really help.   In a few of my trips the table showed that the true wind angle was going to change dramatically over a 36 hour period.    Initially, the true wind angle was 160 degrees.   I often have twin head sails up for this wind angle.   But in 36 hours there was going to be a big shift in wind direction, causing the true wind angle to shift to 50 degrees.   It is no fun to sail hard on the wind.   My table helped me increase the comfort level.   I sailed above the rhumb line for 1.5 days.   I was 50 miles off course and I had bet on the forecast being correct; if I was wrong, we would have gone way out of our way.  But the GRIBs came through and the wind shifted forward.   We avoided the pain of sailing to weather and turned the boat back to the rhumb line.   Smooth sailing. Changes in forecast:  During the voyage I use my KVH v3 to download fresh GRIBS and compare those to the original estimate.  As a back-up, we have a slower Iridium Extreme sat phone and even slower SSB to download GRIBs.  If the forecast changes dramatically, I reassess our plan.   Then I share the new information with the crew.  When I am off watch I will ask to be woken if there are changes in wind direction or speed.   For example I might say, “Wake me if the true wind direction changes 50 degrees or the wind speed goes above 25”. NOAA data I love the Coast Guard and NOAA.   Since your tax dollars are covering the costs, you might as well use NOAA’s great website. Full list of NOAA data Package – weather briefing for NW Atlantic Surf around the site and you can find other regions and plenty of data on waves and wind. Here is the Brazilian weather website  and the Argentinian website. Click on the link labeled “suscripción” at the top of the page to subscribe to the Rio de la Plata weather.  The national weather service of Uruguay was on strike for one of the weeks we were sailing their coastline so we will not post their link.   Windguru is a very popular website that we use as well. Route Planning My next step is to plot the route in Max Sea.   This can be done on the TZ screen at the helm, but I prefer to do this on the laptop.  When the route is done I export it to the TZ touch SD card.   I use the sneaker network, but I could sync the routes by plugging the laptop into the Furuno network at the navigation station.   This video offers a brief introduction to MaxSea. MaxSea Tides from Two Fish on Vimeo.

Ocean Currents I enjoy the strategic aspect of passage planning.   Betting on a wind shift or trying to get the most from ocean currents.   Sometimes there is no option for finesse.   The southern Brazilian coast is into the wind and into the current.   The only strategy is to enjoy a period of pain. Farther up the coast, life becomes much easier as both the wind and current are allies.   Ocean currents are fickle friends.   In a mere 5 miles a 3 knot advantage can become a 3 knot enemy.

To solve this puzzle I found the confusing but very useful ocean current database,  OSCAR.  I became obsessed with currents because they are free speed like solar is free energy.  In a helpful current the boat is going faster without bumpy seas or howling winds.  Many chart plotters have ocean currents as part of the standard package but they display long term averages.   This is flawed as currents change by season, by year and by trending weather patterns.   There are also data bases with ocean currents averages by month, which is better than a yearly average.   Best would be real time ocean current data?   OSCAR by NOAA does just that.   With buoys, satellites and a bit of black magic they show where the current has been for the last 5 days.   To use the data I download a PDF of the region and manually create a route and waypoints.   You can see the process in the image above.   Then I take the waypoints and insert them into our Furuno chart plotters.   This process takes a while so there must be a better way. When we arrived in Tobago an iPad app (Weathertrack)  announced that it had just added support for OSCAR data.  It is 10 dollars and it is a requirement if you a doing a major ocean passage and want to excel in the current.  I still have to type in waypoints but with this app it is much faster than the previous arts and craft style project.  Progress!

Weathertrack showing ocean currents

There are two ways that I know of to assess whether you are in the current.   First is to compare your speed over ground (GPS speed) to your speed through the water (paddle wheel speed).   Paddle wheel speed is not accurate.   The worst part is that the error term changes with the speed of the boat, direction of the waves, if the paddle wheel is in the windward or leeward hull and other voodoo-like attributes.   Another equally opaque technique for finding ocean currents is to measure the sea temperature.   This works great for the gulf stream which is much warmer than the surrounding water; however, the currents in Brazil are not easy to detect by temperature.   The black art of current surfing is one of the fun puzzles cruisers have to solve. If you become interested in ocean currents as a hobby and want to read more visit this University of Miami website.  It was a bit heavy for me but still fascinating. New Crew

We now have a plan. We often have friends join us for longer passages. At this point, I am so excited to get going that I have to control the urge to cast off as they clear the stern steps.  But first, with new crew onboard, we print out and discuss our safety briefing (What to do in case of fire) which covers fire, flood, Man Overboard, MayDay and life raft operation. We also discuss other safety issues such as not getting your hand eaten by the winch, cleating BOTH sides of the traveler, warnings on power winch usage, reefing procedures, tensioning both sides of the screecher reefing lines and other tips to stay safe on Two Fish. We ask that crew go forward with a PFD and wear a PFD at night. We have spinlock PFDs that contain a Kannad AIS system in the pocket of the PFD. This means that if you fall overboard you can become an AIS target for us to track on the chart plotter. We also have jacklines so people can clip in as they go forward in rough weather.

Watch Schedule

Watch Schedule and Crew Duties

Watch Schedule and Crew Duties

We always have one person at the helm set out in our watch schedule. On longer passages, we prefer having a total crew of 4 people. 2 hours on, followed by 6 hours off. We tape the schedule underneath the clock and barometer. The bottom blue box in the photo is the chores schedule. Each crew rotates kitchen cleaning, head cleaning and general salon picking up. I make dinner for the crew at 4pm every day and it becomes a social hour and a great time to share routing thoughts. I turn the generator on to top up the batteries while I use the microwave to warm up the meals Gail has prepared in advance. Baked ziti, lentils with sausage, and spicy chick peas are some of my favorite Gail passage dishes. Sometimes I give crew an area to “Captain”, such as CFO (chief fishing officer). It is a great way to get crew involved and in control of their own space. When we do overnights with just the two of us we play it by ear. I (Jason) will do the bulk of bad weather and dark while Gail will helm many hours of flat seas during daylight.

 

 

 

Final Thoughts Wow that was a long post.  I hope all the links and videos do not hide my thesis.   Planning for a passage can be one of the joys of captaining an ocean-going vessel.   With knowledge comes the power to make better decisions and give confidence to crew that may have some pre-passage nerves. I try to think about what could happen and how to respond before it does.  I also keep adding and improving to my passage plan based on tips from others and lessons learned in the heat of battle.

Lord Electron

The crew of Two Fish believes that Edison’s harnessing of electricity was a step forward.   In support of our belief, we have gone offshore with gobs of electrons stored inside our batteries.   Let Lord Electron, me, give you a tour of the system.
Batteries
We store our collection of electrons in four 6 volt batteries housed in a dedicated locker near the mast.   The batteries hold 780 amp hours.   If you plugged in a load that drew 78 amp hours, after 5 hours your batteries would be 50% discharged  (Easy battery engineers! I know I took a short cut with battery math, but we are just trying to cover the basics).  These batteries are not high tech batteries, as evidenced by the primary use – propelling golf carts.   To avoid damaging the batteries one should not allow them to discharge to less than 50% of capacity.   Two Fish has a conservative 60% recharge rule. There are many young chemical engineers working on new battery types that can be completely discharged.   Lithium ion batteries are a step forward, however, the folks at Boeing might remind us that fires can come with new technology.

One wildly inaccurate way to keep track of your batteries is to look at the voltage meter.   The problem with the voltage meter is it gets fooled by loads coming in or out of the batteries.   The old rule of thumb was 12.5 volts is 100% charged and 11.5 volts is 0% charged.   I will let you figure out the points in between.   This formula falls apart when you have a strong charge coming into the batteries – the voltage meter might read 14 volts.   On the other hand, turn on the microwave via the inverter and your freshly charged batteries may show 11.8 volts.     In the above photo, one can see a knob in the center that selects which battery’s strength is displayed.   The choices on Two Fish are House (a combination of four batteries), starboard engine starter battery, port engine starter battery and generator starter battery.   Most of this post is about the house bank since they power everything other than engine starts.   Actually, in a pinch the house batteries can start the engines,  pretty nifty?
Astute readers will notice that the house batteries, in the above photo, are reading 13.0 volts.  These astute readers will go on to remember that the 13.0 exceeds the rule of thumb’s 100% charge level (12.5 volts). Is Two Fish a special boat that hold a 150% charge?  Unfortunately, no.   When this photo was taken she was plugged into shore power which is one of the many cases where the “12.5 volts is 100% charged” rule falls apart.   I dwell on this point since there is an elegant way on an Antares to address the shortcomings of the crude analog voltage meter.   The VE.net panel gives Lord Electron,  aka Jason, a prescient view of his kingdom.

Battery professionals refer to Two Fish’s type of  batteries  as “dumb” batteries.  Two Fish disdains this industry agreed nomenclature.    Lead acid batteries are aptly named as they have lead and acid on the inside.  This is the similar naming convention used for the peanut butter and jelly sandwich.    As the batteries lose charge, bits of lead fall off their plates and sink into the acid.   When the batteries are charged the process is reversed and the lead plates neatly recombine.  This  process can only be repeated a finite number of times (cycles) before the battery just gives up and becomes lead acid soup.   Live aboard owners typically take 4 years to exceed the maximum number of cycles, but this depends on how often you overstress your batteries by drawing them down to low states of discharge (less than 50%).

I often go to bars and boast that Two Fish can hold 780 amp hours of electricity. However,  this is an exaggeration since I  only use 40% of the total amp hours (312 amp hours) before recharging.   For those that are nodding off this is an important number to remember.   With fresh batteries I need to recharge them after drawing 312 amp hours.   As captain, I need to manage the battery bank.  Let’s say, I am about to take a snooze for 10 hours and the batteries are fully charged.  The boat is sailing and there is plenty of electrical load, let’s say 31 amps.   In 10 hours the batteries will be 60% charged and according to the Two Fish rules will have to be charged.  I try to have a plan about the batteries just like I do about sail plan.   Later I will discuss what items create large loads on the batteries.  We will also discuss how quickly the Genset, the engine alternators and the solar panels charge the batteries.  But first let me introduce the VE.net panel and some of its functions.
VE.net Panel – Understanding the home page “System Overview”?
Tour of VE.net home page data

Tour of VE.net home page data

The above photo is of the VE.net panel that is the brains of most, but not all, of our electrical system.
1)  Starting in the upper left hand corner is “Shore 0 volts and 0 amps”.   I am writing this while lounging at a remote anchorage in the Bahamas, so my shore power is not connected.   When the Genset is turned on shore would read 120 volts and some amount of amps.  Victron should rename shore  “120 volt power input” but I suppose shore fits nicer on the screen.
2)  The icon in the center of the top row  represents the Victron charger/inverter (aka Multiplus).  Victron has cast away the typical charger/inverter name in favor of the meaningless Multiplus.  The charger/inverter is located under the settee and is controlled remotely  with the VE.net panel.   The remote panel reduces time spent on two sports cruisers are always engaged in: cushion lifting and body twisting in confined spaces.
Multiplus Icons from Victron

Multiplus Icons from Victron manual

The icon appears in 3 major flavors as the clipping from the manual shows.   I NEVER want the device off while cruising because then it will not be able to keep track of the amps and will lose count of our percentage  battery consumption.   I do not fret much if a guest mistakenly turns the charger/inverter off as it will find its way the next time the batteries are 100% charged.  The manual calls this process synchronization.   A long motor period or shore power are common ways to give the batteries a proper top-up and encourage synchronization.  It is automatic so I just wait and when the VE.net reads 100%, it is resynchronized.

Most of the time,  you will leave the charger/inverter in “charger only” mode.   This keeps the amp tracker on and allows charging as the name would suggest.  The icon will display device switched off if you have it in “charger only” mode and you are not charging.   Once a charge starts, the icon will change to the equal sign.

The final mode is “inverter mode” which powers any 110 volt devices that are hung off the inverter.   Our inverter can power the microwave, KVH satellite internet, the 110 volt outlets, and TVs.  The advantage of having these devices off the inverter is to be able to heat a cup of soup without needing to start up the genset. The disadvantage is that the inverter is a small, inefficient, power station.   Drawing 12 volts of direct current from the batteries and converting them to 110 volts of alternating current, for the desired use, wastes electrons.   So that cup of soup may draw 1.5 times as much power when being inverted.  Like all things on the boat, one must balance the trade-offs.
Gauges for 110 volt usage

Gauges for 110 volt usage

110 volt items that are not on hung on the inverter are too demanding and need the genset or shore power.   These are: the air conditioning, dive compressor and water maker.  The photo to the right displays how to monitor the 110 system.  In this case the voltage should read about 120 and the load current will depend on the items drawing power.   There are two 110 volt banks, so I need to move the rocker switch to see each bank’s load.   A sistership is investigating changing the water maker wiring to run off the inverter; this would allow them to make water without engaging the genset.   I am waiting to see if that experiment works.   So far, the genset is so quiet that many folks at the helm during passage are unaware that I have turned it on.

3)  The third item of data on the VE.net panel is AC out.   If I turned on my air conditioning, the AC out would not change.   AC out only shows 110 items that are connected to the Victron.   As mentioned earlier the demanding 110 volt items are not connected.   Their draw can be seen on the analog gauge shown in the above photo.
4)  The arrow pointing up from the battery displays that 2.2 amp-hours are being drawn from the batteries by the inverter.    I am charging my laptop while I write this post.   By the way, the inverter requires power even when it is doing nothing.   About 2.5 amps.   So when not inverting turn the status back to “charger only”, NOT off.
5)  There is a battery icon in the bottom center.   Inside the battery it shows the number of amp hours already used.  In my case it is 113 amp hours.    When that number exceeds 300Ah I need to turn on the genset.
6)  To the left of the battery icon is dumb voltage (12.4V).   Despite it appearing on a modern screen it is no more useful than the analog battery meter.
7) On top of the voltage is the hours I have remaining in my batteries at the current run rate.   This does not account for my early recharge strategy, so I do not use it.   Instead, I divide amp hours left(200) until I reach my target recharge point of 312ah by expected average load (10) and calculate I will need a charge in 20 hours.  Expected load is something I learned over time; I will show some numbers on this later.
8)  Finally, on the right hand side of the screen, is a very important bit of data.   It is showing the  NET draw of 8 amps from the 12 volt system.    An example could be that the fridge and freezer are drawing 8 amps but solar is producing 5 amps so the NET 12 volt is 3 amps out.   If the arrow changes direction then your NET on the 12 volt side is charging your batteries.
Final Exam - What does this tell you?

Final Exam – What does this tell you?

As a final exam, lets look at my current panel while on the hook.   The picture to the right tells us what?   1)  The sun is shining because the NET production is 9 amps coming in.  My fridge, freezer and some fans are running so I estimate that the solar is producing close to 20 amps.  2)  The Inverter is on, but should be turned off since the amp cost of having it on is 2.5 amps and there is no usage.  3) No AC loads are on and shore power/genset are off.

Why is the VE.net worth the big bucks?
I have already warned you not to use the crude analog voltage meter for gauging battery status.    Instead, use the fancy VE.net panel that came standard with the boat.   The VE.net machine counts amps.   At the nexus of the system there is a shunt.   From this shunt the VE.net panel watches traffic crossing the shunt.   The panel “writes down in its notebook” any amps coming or going from the batteries.  This toll taker watches the fridge drawing 4 amps per hour for 3 hours and knows 12 amp hours have left my cherished accumulation of amp hours.   It also watches the solar panels produce 15 amps from 10 to 11am and adds this positive to the tally. This is worth some bucks but I haven’t decided how many.
There are some features which I do not use on Two Fish.   For example, the Victron has the brains to help the genset via power assist mode.   This feature would be useful if I  had all 3 air conditioning units running and the genset powering them.   AC units are trouble during peak load, which occurs in the first few seconds of  cycling on.   So if all three AC units cycled on at once you may trip the breaker as it is too much load for the genset.   The Victron could fill this gap for a few seconds by drawing on the batteries.   I have only had my breakers trip once, so I do not feel it is worth making all my 110 systems dependent on the Victron.   In my current wiring, if the Victron fails, my genset can still power my water maker or AC.   If wired my system for power assist they would be dependent on the Victron.  Trying to keep it simple on Two Fish.   The VE.net could also turn on a genset and send many alarms of battery state.   Again, Two Fish is about less.
Device List Screen – Very Important
Device List screen explanation

Device List screen explanation

To get to the above screen click the center button while in the system overview screen.
1) The new screen is called the device list.
2)  13.1 volts (still stupid) is the voltage of the house bank.
3)  +.3 amps is the load on the batteries, close to nothing, so solar must be helping.
4)  And, finally, the crucial data – percentage charge of the house batteries.  We are 99% charged in this photo.   This was calculated by the toll booth at the shunt.   If the battery does not get back to 100% for a long time, the toll booth clerk can lose count. However, this has usually been a very good guide for state of charge (SOC).
5)  The speed of charging- float is the slowest rate of charge and occurs when the batteries are in a  fully- or nearly- charged state.
Not just the captain should know how to check the state of charge.   Guests should be able to glance at this too and notify the captain on the status.
How to turn the inverter on
We turn the inverter on and off many times a day.  Morning coffee, check the weather via sat phone, charge a computer and making ice.   Unfortunately, there is not one easy button to turn on inversion.   Here are the steps.
Checking the VE.net config
The factory sets the VE.net for new owners but it is worthwhile to check these menu items.
1)  Ensure that VE.net knows you have 780ah
2)  Ensure that the maximum charge in ah is 120.
3)  Ensure that shore power can not be more than 50amps.
4) Ensure that battery type is lead acid.
Going through the menus is laborious but it gave me a lesson into the mind of the VE.net panel.  There are 50 or more settings to investigate.  Does it dream at night?
I have highlighted battery temperature because the VE.net is connected to a temperature sensor.   This allows it to charge the batteries quicker and more safely.  As the temperature rises, the charge should be slowed down to reduce the boiling of the acid.   Too much acid boil and I have to pour more distilled water into the batteries.   Way too much and the batteries are damaged.
I also mentioned that you should confirm that VE.net knows your battery type.  The charging equations are different depending on the battery type.  In the mix of menus there is a battery type selector.
Usage
How punch is in the batteries in the real world? Assuming no new electrons come to stay, we can drive our 12 volt toys for 312 amp hours (40% of the total house battery bank).
At anchor

At anchor

At anchor we use about 10 amps per hour.   8 of that is the fridge and freezer.  Add 2 amps if a bunch of lights are on.   Fans are less than an amp.   Anchor light is nothing.     The number can rise to 20 amps if we are charging laptops and watching TV on the inverter.   In short we can be at anchor and only need to Genset every third or forth day.    We sometimes push it buy turning on the ice maker.  This beast consumes over 10 amps and will cause the genset to be on a day early.   When we run the genset for a full charge (60% to 90%) it takes 3 hours.   With some conservation we can  last 5 days without genset if we get sun and did not turn on the ice maker and other power hogs.  If we are carefree we charge every 3rd day.

On passage at night we burn 15-20 amps; this is used to power the huge collection of navigation electronics (Radar, Furuno displays, autopilot and the fridge/freezer).    We have run the boat with only one screen, but this does not save a lot of amps.   US Coast Guard does not recommend traveling without the radar and I agree.   So we are stuck. On 100% sailing days we need a 2-3 hour charge every day.   Here is the math of our consumption vs our production.  (24 hours x 17 amps =400 amps of usage,   100-150  amps of solar and 250 amps of genset production).   I use dinner time as a nice way to sneak the genset on to power the microwave.   All my guests comment on how little noise the genset produces.   Any passage with a large amount of motoring will also produce excess power and the batteries will be at 100%.   Great time to make ice and charge laptops.
Here are some sample loads for the 12 volt system:
KVH on inverter   15 amp hours
Ice Maker                14 ah
Engine blowers     13 ah
Underwater light    10 ah
Spreader lights      5.4 ah
Fridge/Freezer       8.5 ah  (4.3 ah each)
Inverter                    2 ah
All Stbd Cabin Lights   1.8 ah
Nav lights                1 ah
VHF                           1 ah
Cockpit lights          .9 ah
Stereo                        .6 ah
Wifi router               .5 ah
Fan at hi                   .4 ah
Stair lights                .3ah
Furuno RD33        .3ah
Vesper AIS                .3 ah
Tri-Color                   .2 ah
Anchor light           .1 ah
I plan to change the wiring for the boat-at-anchor set-up.   I wish to have a few low power items on.   AIS, RD33, wind instrument and VHF will be a good at-anchor combo.   Currently, when I turn any instrument on, my DST and fish finder turn on and consume over 2 ah.   A quick rewire or an additional switch for the two transducers, and I will have my low power set-up.
Production
We have four ways of charging the batteries on Two Fish.
Solar Panels
The solar performance data are limited since the VE.net displays net 12 volt consumption.  Please bear with my crude approximations.  Like a typical sport  fisherman, I will start with my all time record solar production.  Near the equator I captured 35 amp hours at noon.   In sunny areas, but farther north, I think a peak production is 20 amp hours.   Assuming I get 3 hours a day of 20 amps and 5 hours a day at 8 amps this would produce 100 amp hours per day.   Again, I need better metering to understand the precise numbers.   The fridge/freezer complex consumes 200 amps in a 24 hour period.   Solar is nice but does not kick my diesel habit.  Solar is great at topping up the battery from 90 to 100%.   It is silent and can accomplish the slow charging from day break to sunset, stopping at the green flash.
Generator (Genset)
Generator (Genset)

Generator (Genset)

The generator on Two Fish produces a very powerful 7.5 kilowatts.   If the batteries were exposed to this much energy they would boil off their acid solution and become permanently damaged.   The charger/inverter limits the amps allowed in based on user input and the state of charge.  Assuming the batteries are 60% they will accept the maximum user defined charging.   I allow 120 amps, which is close to the maximum the batteries can handle (per Trojan battery manual) and is the the charger/inverter’s maximum power.    During this phase, one can see 120 amps coming into the batteries on the front screen of the VE.net.   However, after one hour of charging the batteries do not contain an additional 120 amp hours.   Charging is crude work and plenty of power is lost.  My rule of thumb is in one hour my state of charge will improve 10% or 78 amps.  So 42 amps are dissipating.  In practice, if you want to take batteries from 60% charged to 90% charged you will need 3 hours of genset.    This is a great time to produce two full water tanks, warm the hot water tanks, use the microwave, check the sattlelite weather and charge computers.   I like to be at 90% at dawn so the sun can top up the batteries during the day.

NOTE for charging with the genset
1)   Turn all breakers in 110 system off.   Turn off inverter at the VE.net panel.
2)   Start the genset by pressing start button for 10 seconds and wait 2 minutes for warm up.  OK, sometimes I go earlier.   Is the mushroom open on the genset locker?
3)   Turn on the breaker switch labeled Gen first.   Then flip the breaker switch labeled parallel on.   Then slowly add load.  First, turn on the charger breaker.   In 30 seconds the VE.net will register the charge coming in.   Add other items as you wish but spread out the load.   Keep an eye on the amps.   Per the manual, the genset likes between 25% to 75% load.   I usually run between 20 to 40 amps of items.
Alternators on the Engines
Alternator

Alternator

Each engine has an alternator that sends a 12 volt charge directly to the batteries when the engines are running.   The number of amp hours is dependent upon the number of engines and their operational RPMs.   When in cruise mode, we often produce 80-100 amps, a number on par with the maximum of 120 amps.    We are not sensitive to this charging speed since when the motors go on they tend to be on for plenty of hours.   If our genset ever stopped working, the engine alternators could charge the batteries and run any 110 items that are hung on the inverter.   However, we could not run the water maker without the genset.  You do not need to have the charge breaker on for the alternators to charge the engines.   The alternators have their own charge controllers and could function if the Victron was not operational.   The charge they produce is seen by the VE.net when it passes over the shunt.

Shore power
I have not done proper speed tests for charging while on shore power.   It has not been an issue, since one tends to be plugged in for 12 hours at a minimum.   When connecting to shore power there are a few tips we keep in mind.
Shore power turned on

Shore power turned on

1)  We always multimeter the shore power we are about to use to confirm it is the proper voltage.   The three pairs of socket holes should produce 120, 10 and zero volts.    They are usually well-protected so you must be persistent with the probes.

2)  Examine the shore power for amperage.   Two Fish has two 30 amp shore power cords.   Marinas often have 50 amp service.   If this is the case we use our pigtail (bought at West Marine in Puerto Rico) to split the 50 amp derive into two 30 amp services.   We then plug our cords into the pig tails.   Marinco makes our pig tail and we like it so far.   It has a flashlight built it and a nice locking mechanism.
3)   Before plugging in, speak to the marina staff and ask the status of the power point, the amperage and voltage.
4)  Turn the boat off!   Ensure all of the 110 volt breakers are off.   Ensure the Shore 1 and Shore 2 power are off (they are on in the photo).
5)   Attach pig tail to power point and ensure the blue light on the pig tail turns on.
6)   Attach shore cords from our Glendinning automatic cord spoolers.   After attaching, ensure the breaker located in the starboard aft locker indicates green for power on and that there is no red light for reversed polarity.   Most Antares do not have the Glendinnings so they check polarity on the main electrical panel.   We find the Glendingings are a good, but not a must-have feature.   I love how they so cleanly stow the cables in a spot I would never use.   Your cables exit at the stern, which can be tough if the power source is at the bow.   We have had no service problems and they spool easily if done carefully with one person feeding and the other person pressing the spool motor switch.   Sounds complex but it is like storing a garden hose.

7)  Turn on shore power 1 and confirm 120 volts and no amps.   Repeat for shore power 2.   If you can only plug in one shore power service, then plug in shore power 1.   You will then need to turn on the parallel switch to use 110 volt items on your second bus B.   Beware – you only have 30 amps so do not turn everything on at once.
8)  Ensure the inverter is off.
9)  Turn on breakers.   I start with the breaker for the inverter/charger.    This allows the 110 power to go to the charger.   It will take almost 30 seconds for this to appear on the panel, be patient.  When the power has come to the panel you will see the icon change, amps going into the battery and a charging state (i.e. bulk).
10)  We detach in reverse order.   Turning off breakers for individual items first and unplugging from the power point last.
Shore Power in Foreign Lands
Our Multiplus (charger/inverter) is set to accept 110 volt power and charge 12 volt batteries.  We would need to buy more equipment to plug into a 220 volt marina.  When cruising Brazil, we chose to never plug in to shore power.   I was fearful of the quality of marina power in Brazil after a sister ship had severe damage from poor marina wiring.   The loss in power of not using shore power was trivial.   We never had weather in the marinas where air conditioning was a must and we charged the batteries with a quick run of the Genset after a couple of days.   Solar power kept charging to an acceptable minimum.  I knew world power comes in two flavors, 110 and 220.   But I did not know 220 volt power typically comes in 50 cycles and 110 volts 60 cycles.   If you transform 220 volt power into 110 volt power the Victron equipment will accept this power. However, you will now have 50 cycle 110 which is not expected by some of the electric motors.   Imagine a biker who is designed to pedal 60 cranks per minute dropping to 50.     With some electric motors this can create long term damage, while other motors do not mind the odd cycles one bit.   I do not have a clue which motors on Two Fish are sensitive to the cycle issue, because I have stayed with only the correct cycles.    I know of an Antares that ran their heat and AC on 50 cycles for a year and the AC motors had no service issues after 6 years.   I also have heard that on one boat the washer/dryer would not run on the wrong cycles since it had a cycle sensor that forced and auto shut down.
Battery Charging Phases
Battery charging phases
There are 3 phases for charging the batteries, according to the marketing guys at Victron.  (Bulk charge – for batteries less than 82% charge,  absorptive charge for batteries 82-92% charged, and float charge for almost-full batteries).   As the batteries get more charged, they need a lighter touch when putting in additional electricity.  Rather than using the goofy marketing terms on the VE.net panel (5th line down “Charge-float”), VE.net will show the amps being directed at the batteries.    Some real data from my time charging the battery with the genset.
At an SOC of 65% the batteries were taking in 120 amps.  
At an SOC of 77% the amps dropped to 115.  
At an SOC of 84% there were 113 amps flowing in.  (marketing term change from bulk to absorptive)
At 86% SOC it was at 98 amp.  
At 88% it dropped again-to 75 amps.
By 90% SOC, the batteries were only receiving half of the initial punch – 60 amps.   I usually turn off the genset when the amps coming in drops under 90.)  
The amp numbers bore out with the stop watch.   As the amps dropped the time increased for the SOC to increase by 10%.    Initially 10% gains could be recorded in under 1 hour while towards the end almost 1.5 hours.
Note:   I turn off my inverter when I have the Genset or shore power on.   Not sure if the Victron knows to do this on its own but just to be safe I do this.
Battery Monitor

Battery Monitor

Battery Monitor

The complete  Antares Victron installation includes the Mutliplus charger/inverter, the VE.net panel, a solar charge controller and the battery monitor.   The latter is a small blue box  located behind the electric breaker panel.   There are a few dip switches which should be set at the factory to your battery type (worth checking).   After that I have not touched the box.   Its job is to measure the batteries and send its data to the VE.net.   Almost like in the old PC days, it is the box and the VE.net the monitor.

 
Solar Controller
MPPT  Solar Charge controller

MPPT Solar Charge controller

Solar panels are still a bit of a mystery for me.   Firstly, my controller requires a reboot once in a while.  I hope to get this fixed in Fort Lauderdale in 2 weeks.   Secondly, the system does not offer much insight as to how much energy it is producing.   I will see if I can add some meters to the system.   But to the system’s credit, it works without the need to press buttons.   If it is sunny, it will charge the batteries.   The solar controller is just like the charge controller on the engine alternator and the Victron charger.   It senses the battery state and only sends the right amount of energy.   The rest gets sent away in heat.   The particular model has MPPT(Maximum Power Point Tracking) which I am told is key to handle sunny days.

Final Thoughts
This post makes the boat seem complex.   And it is.   But it is set up in a forgiving way, so it will not burn down if I forget a step.   We have been very happy with the set-up so far.   Other owners have added a wind generator. We are waiting to better understand our usage. I would be tempted to buy more powerful solar panels, but  I will wait until the controller issue is cleared up.   I plan to research possibilities for power produced while towing, since I turn the genset on the most during long sailing passages. However,  any purchase is a while off.
Would I get higher-tech batteries?  Not yet.  I do not mind going forward and adding a bit of distilled water and I enjoy that lead acid batteries they are bullet proof and easy to replace.   I do read articles on the amazing power of lithium ion but I will wait for the that technology to improve.

Keeping Watch, or, Is Someone Moving my Market?

A while ago, early in the morning, I (Gail) was on my first solo watch. I began thinking about some of my friends back home and started writing an email to tell them what I was doing. Usually, these emails in my head are one-way conversations. This time I wrote it down.

When on a passage for multiple days, someone needs to be on watch at all times. This is like today’s world of 24-hour markets where someone  always needs to be holding the trading book. But how do you know where to go, or what to look out for? At the start of a passage, the Navigator (or in market lingo, the Chief Investment Officer) will set a series of waypoints. The Navigator does this based on experience with the area, weather predictions, and knowledge of the boat. This is like your Strategic Asset Allocation. But how do you track your performance? The boat has a compass and GPS, just like the pricing  functions needed for Asset Allocation; GPS is your instantaneous pricing and the compass needle is your allocation.

Suppose you have a few asset classes and are trading (or using your rudders to steer) to maintain that allocation using an automated trading system (usual conditions such as continuous pricing, liquid assets and homoskedasticity apply). On the boat, the autopilot serves this function. It is programmed to either follow a course (allocation) by steering the boat at a steady angle to the wind, according to a compass direction or heading towards a waypoint. Strategically and tactically, you can not just stay on autopilot and walk away. You need your Network (Eyes and Ears), Bloomberg Terminal(Chartplotter/Radar), Financial Times(Weather Reports), and S&P 500(GPS).

Like market news, the weather report’s value depreciates over time; it is something you would like to get often. We can fetch weather reports by downloading electronic GRIB (gridded information in binary form) files while offshore. The fastest way is when we have a working cell modem but this only works within a few miles of the shore, near towns. Cell modems are like having your servers right next to the exchange using fiber optics. In Brazil, it also requires a Brazilian SIM card, which is like having a local banking license since it requires a Tax ID. The next best way is to use our KVH satellite phone, which is like DSL. The slowest method is to use our Iridium satellite phone; this is like a 2400 baud Hayes Modem – painful but it can come through when needed. What if I don’t know how to interpret this weather info? I can look to my Market Strategist, aka a Weather Router, who looks at all of the data and gives me an interpretation of where and when I should sail that is specific to my situation.
We also have a Radar and AIS, which appear on our chartplotter, and like your Bloomberg terminal tells us current news of interest. Radar sends out radio waves that reflect back from other objects, such as ships, buoys and land. I just looked at my Radar screen. A new entrant in the market? Will she be a problem? Is she following the same Asset Allocation as I am? Will that crowd the market? Maybe I should change course or delay action so as not to be affected by her. I slowly steer the boat a bit to the right.
AIS (Automatic Identification System) is another thing we watch. We broadcast our ID via AIS so that other vessels can see us. We also have a radar reflector to make it easier for other boats to see us.
Just like anything else, using your brain and taking your head out of the boat/screens is the best way to confirm what is going on. Sometimes you also need to pick up the phone. We can use our VHF radio to do this. Fortunately, in the ocean, as opposed to financial markets, your counterparties are best served by full transparency and if you hail them, they will tell you exactly what they are doing. I am not sure how the existence of Sunspots will affect this equilibrium state.
Now I am watching the other boat follow its path away from me. I readjust my Tactical Asset Allocation back to the Strategic Course and we are back on our way.
Next week’s lesson: Volatility Trading, or, Using Sails.

Putting a Boat in Park

The killer app for boats would be an ability to shift into park like a car.   Instead, one employs many lines, anchors, mooring balls and more to hold the boat in place when in a harbor.   On our cruise, we tried a variety of methods for putting the boat in park after the sailing day ended.

First, life at a dock  is a cake walk.   You attach the bow/stern lines to dock cleats, add a few spring lines for good measure and adjust your fenders.   Expect to lose sleep only when your neighbors’ late salsa music wakes you.

Mooring Ball

Mooring Ball

The next level up is a mooring ball.   This is an easy move in the BVIs where the balls are serviced regularly and have a friendly pennant line to make attaching to the ball a breeze.   In Uruguay, the balls lack the pennant line and are also impossibly heavy to lift, so we used a modified strategy.   Rather than grab the mooring ball from the bow,  I maneuvered the boat so that the mooring ball was near the stern steps and Gail gracefully attached a long line which could then be walked to the bow.  We hopped in the dinghy to attach to a second line to make a bridle.    This was also stress free – until 2 am when the tide ran out of energy to flood and switched to ebb.  This was when we realized that the mooring balls were not spaced properly for a 44 foot boat.   This news did not arrive via a friendly email but by a gentle thumping noise.   As I am a new boat owner, I leapt out of my skin and raced on deck to check on what was left of my stern.   Not even a scratch.   Gail used the boat hook to joust with the mooring ball  from the boat from 2 to 3am until she was releaved of duty by a change in the wind.   The sailboat companies do not list those early wake ups in the advertisements.

Anchoring is a topic about which volumes have been written.   Ask four sailors how to anchor and you will get 5 opinions.    Dropping and raising anchor has become much more civilized since the time of Nelson.   As long as your thumb is in decent shape, you should be able to press the up button on the windlass and from the depths will come pounds of chain, an anchor and sometimes unwanted mud.   No octopuses or treasure chests have come aboard Two Fish, yet.  The anchor can be raised from the bow or from the helm.

 

Mediterranean Moor

Mediterranean Moor

Where the fun really started for Two Fish was the Mediterranean moor.   A Med moor is like tight mens’ swimsuits – a European convention that the US has not embraced.   The boat crew drops the anchor and then reverses towards the sea wall, where stern lines are attached.   The result is that you can hop from your stern to the shore and buy a fresh baguette.   The sailing brochures fail to mention that this type of mooring can raise your heart rate when there is a crosswind and the marina staff are watching you as if it is the Sud America Football Cup.  Med mooring with a cross wind is like parallel parking a car except the spot is moving slowly away from you.  What is moving seemingly quickly towards you is another boat or, in my case, a metal barge.  Like most things in life, there is a trick to make Med moors easy.   Just drop the anchor upwind of your desired position on the seawall and the cross wind will put you in the correct spot.     The process for leaving a Med moor is to quickly lift anchor before contacting your neighbors.   Again a trick can help.   BUY VERY LONG DOCK LINES.   250 feet is a great line since you can go forward and raise your anchor while your stern is still attached.   Ah, Mr Crosswind I have defeated you again.

The next day, the mooring gods came up with a new trick.   The marina staff came by moments before our departure and dropped their maintenance vessel’s anchor and chain on top of our long and heavy anchor chain.   We waited patiently so as to be good guests.   The staff then realized their mistake and tried to rectify the error.   This is when Keystone Cops began.   The marina staff dinghy had a 6 hp engine.  Not enough power to pull two kegs but the determined dock worker had a plan to execute, even if the laws of physics were against him.  Newton be damned.   His plan was to use sheer arm strength to lift our strongly-set 75 pound anchor from the muddy harbor bottom.  Finally, he realized the futility of his mission and decided to duck their 3 pound anchor under our chain.   We were free to go.

Putting the boat in park is always an adventure.  Just think of this the next time you park your car at the mall.

Gail Takes Basic Coastal Cruising Class

We have recently spent a lot of time buying tools, learning about engines and other non-sailing boat activities so I thought it might be good for me to learn how to sail. Not that I haven’t sailed before. Jason and I raced Vanguard-15s for a few years and we did take a course in BVI (click here to see the post), but I still need to develop a better feel for the water and work on my ability to execute actions quickly.

I decided to enroll in Manhattan Yacht Club’s (MYC) Basic Coastal Cruising Class (aka ASA 103). MYC is a hidden treasure. They have a fleet of J-24s and a J-105 docked right at the World Financial Center. Jason has belonged there for over 20 years but because he was mostly racing J-24s, I never accompanied him. I decided not to start at the very beginning level – Basic Keelboat – but to go out twice on my own with an instructor and then go to the class.

My first sail was 2 hours with instructor Andrew. When I got to the dock, the boat was fully rigged (yeah!), except for the Jib because he wanted to see me tie a bowline. Fortunately, I had practiced that the day before. For anyone looking to refresh boat knot skills, I highly recommend Grog’s Animated Knots app. My big accomplishment was steering the whole time we were out. We had some great weather – wind 10 to 15 knots – and I learned first hand about weather helm. Andrew’s calm demeanor was great and he interjected with some very useful tips from time to time. Good news again when we got ashore – they were using the boat again and no de-rigging. Did I mention that when we sailed Vanguard-15s I was a bit of a Prima Donna? When we got back to the sailing club, I always got to shower while Jason de-rigged the boat. That may change soon.

The next week, I went sailing with Andrew again and told him I had two goals: 1) Control both the tiller and the main sheet, and 2) not get seasick. So I made sure to take Bonine and drink lots of water and he helped me get more comfortable at the helm. Progress!

So now for the big event. I was slightly trepidatious about two full days of sailing. Ever since a few bad seasick experiences last year, I get slightly nervous about going out. I took my medication and drank a lot of water and I was fine for both days. The sailing couldn’t have been better. Our instructor, Javier, was also great. He was calm, knowledgeable and very thoughtful. We rotated being at the helm, so I had to forget about being timid very quickly. On our first day we sailed to the Verazzano Narrows Bridge and back. Lots of traffic in the harbor made it challenging, but with many lookouts and voices on the boat, we were safe. We all had our own points of view – mine was that we were in a cruising course and really shouldn’t need to tack and gybe so much. Others were focused on finding refreshments or going for a swim (Yes, in the Hudson. Not for me.) Needless to say, Javier didn’t really agree. We tried to convince Javier to take a break at Red Hook – some of the crew were focused on some afternoon caffeine but our request was vetoed. We also practiced man overboard, or lifejacket overboard and docking. Everyone had to take their turn steering through both skills and we all made it.

Rolling Hitch Knot

Day two the wind was light (1 knot gusting to 2 knots) in the morning so we stayed on land and took our exam and practiced our knot-tying. Javier was a good teacher because I finally can remember how to tie a rolling hitch! We also all passed our tests! All of those pop-quizzes Jason has been giving me have finally paid off.

We headed up to the George Washington Bridge very slowly because the wind was still light, reaching back and forth across the Hudson River. As you go North, there are fewer boats, so that part was a bit more relaxing. Eventually we anchored and took a break at the Inwood Marina. We were again turned down when we asked to let one of the crew swim ashore and fetch some refreshments. Maybe when we come through with Two Fish the Marina part will be open. I had fun using the Navionics iPhone app to check our depth, report on the windspeed at Robbins Reef, and record some of our track. By 4pm, the wind had shifted and picked up during our return, so it was a fun sail back and we were all ready for some drinks at The Mermaid, MYC’s marina barge.

It was fantastic for me to be sailing and to gain a few more skills and increase my confidence. Mostly, it was great to have a fun time on the water and remember what all of the current planning is working towards. I hope to go out with the MYC boats a few more times this summer and keep learning. –Gail

Learning Knots

There seems to be a pattern. Jason, who is focused on making sure we are ready for our adventure, suggests to me, Gail, that we should really get better at xyz and we need to either a) buy a book, b) take a course, or, c) practice. The first two or three times he mentions it, I try to ignore him by saying yup, mumbling, or deleting the email. It’s not that I don’t want to do these things but somehow, even though I don’t have a day job, I always feel as if I have too much to do already.

Did I mention that Jason is a bit tenacious? So, after a few more nudges, I act on the suggestion. What usually happens after that is that I end up more interested in and excited about the particular skill than Jason was in the first place.

And so it was with learning knots. Whenever someone asks me to tie a fender to a lifeline I panic, thinking that the fender will come loose and end up in the ocean. Despite the fact that I really needed to learn this crucial skill, I hoped we could just delay the lessons.

Years ago, Jason taught me how to tie a bowline and at least that one has stuck with me. Last year, in our BVI class we learned a half-hitch, a rolling-hitch and a few others. The knowledge of all of those had somehow evaporated from my brain. If we want to join the ranks of great sailing salts, and hold onto our rigging and dinghy, we need to know how to tie useful knots for many situations.  The development of sailing knots goes back thousands of years and the knots have been meticulously refined.   Just imagine if the Windows operating system went back thousand of years-it might never display the dreaded blue screen.

Tying Table

So off Jason went to build a tying table. And now, I am its biggest fan. Using the app, Grog’s Animated Knots I can finally tie a few more knots and may just lose the knot in my stomach at fender time.  — Gail

Hamble School of Boat Repair

Learning about boat repair is one of our biggest challenges.  For too long we have lived the NYC doorman and porter lifestyle where home repair ,including some light bulb changes, is outsourced.   That is not an option on a boat where maintenance and repair are ongoing, even on a brand new boat. To cure our lack of skill we found a 7 day course that covered all things boat repair.   The only place that offered such a complete curriculum was in the UK at The Hamble School.  The class was excellent and a real confidence booster.   It was also an advertisement for our brand of boat since time after time instructors would tell us “the proper way to do xyz” and we would consult the Antares manual to discover that Antares had done it the “proper way”.   The English teaching style is a bit harsh but you learn quickly that you have made a mistake.  Reminds me a bit of the days back at my prep school, EA.

Coastal Navigation Class

Stuffed Penguin

 

We started studying costal navigation via the ASA study by mail program.  The material was comprehensive but it was a bit difficult to find a proctor to supervise the test.   So we enrolled in a class via New York Sailing Center.  Steve Card was a great teacher.   The classroom was an apartment on the Upper West Side.   Notable items were 250 playbills and a stuffed penguin that seemed to come alive as the breeze tickled the feathers.   All joking aside, it was a great class. Now we need to study for the exam.

UPDATE: We Passed!
