Electric Yacht System Works Great!!

My Mood 34 is back in the water. The Electric Yacht 260i system works perfectly. Docking and getting to the mooring are so much easier with all of the torque available instantly.Continue

I just finished an installation of an EY Quiet Torque 5 with a 36 volt flooded battery bank in my 1973 Herreshoff America Catboat. All parts of the system installed easily and appear to be top quality. I am looking forward to getting on the water.

When there is enough wind to sail there is always power. One trip we motored for 3 hours then the wind came up. We used the regen all night to charge the house battery then shut it off the last 3 hours before we would need to power in to anchor. Batteries were up to 99% when we needed them. Only used 10% when we anchored.

I will post on some of the hard parts when we start going up  the River.

One thing I would like to do. A switch to Lithium Batteries would reduce generator run time after a trip when we need to top up the lead acid.

We are about to start a trip I never thought about when we went electric. I plan to send in comments on stages of the trip as it wont be nonstop. Going up the St Lawrence so there will be motoring imvolved.

Good photos and discussion on your websites, Randy and James.  It is helpful to hear what equipment you used and how you rate it.  I'll look forward to more photos and discussions as you proceed with the installation and testing.  Thanks for sharing.

I am most likely still a week away from testing my setup, but I do have lots of pictures http://www.deny.org

Randy, I hope you document and take photos of your install.  In the near future, I will be installing a 360 in the 47' cutter that I am building here in New Mexico, and will need any guidance I can get.  I was interested to read your thoughts about the ABYC standards on electrical systems in boats.  I'm building a boat from scratch and have been building my electrical system as I went along - doing common sense things like using only marine grade wire and connecters and to solder all slices.  Here in New Mexico I doubt there is any marine surveyors I could ask about things.  Is there any guidance on the web that would be useful?

As we get ready to install our new Electric Yacht 360 drive system in our 45’ Friendship Sloop, a little American Boat and Yacht Council ( A.B.Y.C.) research needs to be done first. As a boat builder, mechanic and marine surveyor with S.A.M.S. I often survey boats that have been modified or repaired by the owner. The problem starts when the ABYC standards are not followed by the owner. A wire is not just any wire. Its use, load and the environment it will be used in are all factors that must be considered. Wet cell batteries or AGM all need to be installed so that they are safe and perform as needed. ABYC answers all these questions and has the recommendations you need to follow when doing work on your boat so that it is safe and you can get insurance.

 I will admit, the ABYC standard reads like a law book, weighs 50 pounds, and will put you to sleep, but the good news is you don’t have to read it. Most, if not all, marine surveyors love boats and love to show off their knowledge, call one for the answers. I’ll bet you will get the answer you need and help making sure your conversion is safe and ABYC compliant at little or no cost.

 For us we need to bring AC power onto the boat that never had AC power. We need to make sure our AC power inlet and downstream wiring is all ABYC compliant and up to today’s standards. When we are 20 miles off the coast and it picks up to 30+ Knots, I’ll have enough to worry about. Following the ABYC Standards could make all the difference.

 A trick for anyone converting a wooden boat.

  Use Cedarific cat litter to pull oil from the frames and planks. It won't dry out or dissolve the hard seam compound or melt any wooden finish like varnish or paint. 

Fill the bilge let sit for about a week the vacume it out smells great ( just don't let the cat near the boat).  Any left over will float next spring and can go through a bilge pump without binding it up.

In Maine we have a unique program that allows a commercial documented vessel to replace a old "dirty Diesel" with a new clean or Tier II engine. Well we are a commercial documented vessel and we applied and got the matching grant funding to switch out our old engine to a clean electric one. In fact we are the first vessel in Maine to do so. 

The grant stipulates that we drill a hole in the block to prove that the old engine has been removed from service. Well it is near deer season up here so we put  hole in the block Maine style.  We shot it   God love the Federal Government

 And it was Gary's wife's rifle that we used!!!!

Oceanvolt references

I am looking at buying 2 SD15 KW saildrives, 8 LiFePO4 batteries, 2 14KW DC Diesel Gensets and a solar charger/controller from Oceanvolt. They provided several references of people who had their systems in catamarans so I contacted all of them. Every one had a good story to tell! Sure there were a few problems, but the owners all said that Oceanvolt support was impressive. Does anyone in this group have a history with Oceanvolt?See More

All Ahead Full

So today we put both the throttles down on the Ray controllers and were calmly pushing 100 amps a side on the motors and moving along at 6.64 knots according to my OpenCpn. Here is the track2.gpx for google earth or back to opencpn if you like to compare numbers otherwise the AIS track here >>…See More

Sea Trials Continued

Solar sailing down the Fraser almost making power.  Coming back upstream was interesting as we had to make prop for 50 amps a side so 100amps minus solar so 85amp deficit more or less to obtain our 7km/h upstream against probably 5 knots of current.https://youtu.be/rEA-u3lZqVg…See More

New Battery technology

I  keep  seeing announcements for new battery technology, most  recently  from   Renogy Solar  with  the Lycan Powerbox, but alas none of these  announcements  come with technical or  price information. Does anyone on here know of any  real break through battery technology  that is truly on  the market? See More
