Re: [Electric Boats] Comments from the group please 70 ft catamaran

 

Do you have an estimation of the finial tonnage? That would be a little more useful then the length for motor sizing. Either way out side of Mastervolt there are no marine option in the 50hp range, so you will be looking at a car conversion kit.   

A question for you was it hard getting the captains license to pilot a boat longer then 64 foot? How long does  it take?

The hulls are now being constructed, this vessel WILL be powered by electric motors. I will be using the largest (235 w) power per sq ft solar panels I can find. The rest of the system has not been specd yet, but I have a lot of research (3 years). Comments please on components and or complete systems. I am not going to buy a retail packaged system due to cost. Recommendations for batteries, motor type, controllers, voltages of the system, generator, regeneration, drive type, caveats, experiences.
I expect a minimum of a 30 HP drive for each side, probably closer to 50. Large prop so drive pod is not possible.
Thankyou so much. A brief response is sufficient if you don't have time to comment.
