Bristol 32 Electric Conversion Project

By Greg Martin              Converting s/v Intrepid into an electric boat, I have to say honestly, was a real pain in the #$^&. But in hindsight it was definitely worth it and it can be (and was) done by an inexperienced amateur. Working part time by myself, and making lots of mistakes, the project took me…

Mini BMS

I'm closing in on making the switch to lithium. I am using a Mini BMS for the battery management and having trouble getting the AC relay for the charger to reset. The "key" terminal on the head board is connected to the switch but it does not reset the relay when cycled on and off. If I physically disconnect and reconnect the 12 volt supply to the board the AC relay resets. Does anyone know what the "key" terminal on the head board wants to see?

Electric sailboat endurance estimates and experience

We talk a lot about range in miles at various speeds, but I think for cruising sailboats the real question is how long can you go without needing to recharge. This includes house loads and motoring.When we had Snow Lily (Tartan 34C) repowered my goal was to get 5 to 7 days cruising without needing any sort of recharge. I was cautioned to go with diesel as range would be a problem, but I really think in terms of sailing and not motoring. The motor is only for in and out of the tight marina, on…See More

Post your boat speed !!!

I'd like to try to get a handle on boat speeds.So please:  post your boat details and speeds!  I'll get the ball rolling....- Defintion of "takeoff weight":  just like aircraft:  entire weight of craft + batteries + humans + everything.  If you don't know, take an educated guess.- conversions fyi:        1km/hr = 1.6mph        1km/hr = 1.852knots- HOW I MEASURE SPEED:   I find GPS's generally suck at reading low speeds.  What I do is take two known points (the corner of my dock, and the corner…See More

Solar Electric Pontoon Boat Conversion

Hi All,I just completed conversion of my 24' pontoon boat to 100% solar electric (no shore power or other external charging).It's no speedboat but I am very happy with the results in the given application (small freshwater inland lake, summer-only usage).I think the Torqeedo, solar modules, and charge controllers are generally well enough known on this site, so I will only add that I am particularly satisfied with the 48V/50Ah Gen 2 Chevy Volt battery module performance.  At $850 with shipping…See More

Field data from several runs of my St. Pierre Dory

This weekend I had a chance to collect data on the power requirements for my St. Pierre Dory while under way.  I thought it might be of interest to those trying to size a system.It was a calm day and I  recorded speed from my GPS and power from my ammeters.  These numbers are the average of at least 4 readings at each power level going both into the wind and against and with the ebbing tide and against.  The tide was relatively calm and the wind as well so the readings did not differ by more…See More

I converted my 2016 Bayliner 175 to All Electric

I recently finished converting my 2016 Bayliner 175 to all electric. It cruises nicely at 25 to 30 mph. It is powered by a 147hp electric motor.The range is 25 miles. It takes 12 hours to charge at 120v and 4 hours at 240v. With respect to weight, it was a wash after the conversion. It comes in at a little over 1,900 pounds. The max speed is 53mph. I did the complete conversion myself in my garage. If you are interested in taking on a project like this, I would be more than happy to help.I have…See More
