Taking on another big project and just looking to see if anyone might have any feed back4 years ago I restored a 33foot Morgan O/I and repowered with a Thunder Struck 10kw drive and a 310ah FLA battery bank I am very happy with this boat and lived aboard for 3 yearsBottom line I met a girl that likes living aboard as much I do so I bought a 43 foot Gulf Star trawler no mistake about it. Its a huge project but it is moving alongIt is powered by Perkins 6-354s my plan is to sell them and repower…See More
In the mid 1990's Phil Bolger, a naval architect from Gloucester Massachusetts, designed an electric runabout for the home builder called the Lily. Recently there has been some interest in upgrading the design of the propulsion system and batteries to make better use of current technologies. Here are my suggestions for upgrading the original system in Lily. The MotorsIn 1995 Lily was set up with a 24 V trolling motor, and I consider trolling motors to still be the most cost effective option…See More
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?
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
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
