Deck officer, how much power would an array like the one pictured in your post produce. How many batteries would you need, not the lithium but agm's would you need to hold that power in one day. Just trying to get a grasp on what's involved. Thanks
Hi; I've just joined this forum and am interested in feedback/info re an electirc powered trawler:
My idea is to buy an 1980's ish trawler; fiberglass; approx. 34' to 38'; no flybridge; something along the lines of a mainship pilot but doesn't need to be one specifically. don't care about the condition of engine or interior per se' but want a solid hull.
Replace engine with a low rpm high torque electric motor and fuel tanks with rechargeble lithium-ion battery bank; install solar panels along with foldout 'wings' for additional solar radiation collection; also install some type of wind generator..........
Thats the basic thesis; would like info on types of motors, batteries; solar panels etc; anyone done this??; etc.
I'm somewaht amazed that in this day where its time to get off fossil fuel that the over a hundred years old idea of larger electric powered boats is not utilized........ intjonn
Regarding your "ugly" comment. I am a great believer in "Beauty is as beauty does."
Dave,
Very good post. An efficient hull you left out is the Chris White designed Buzzard's Bay.
Dave,
I enjoyed your link, 13 years ago one of my early projects also used the Etek PM motor. Back then you could buy one for $375, so I bought 2. One has been tortured in EV racing, the other is still unused. It is unused because the first one has never had an issue and still on original brushes.
What you need to fulfill this dream before you go to the "Great Beyond" is a "sail boat!" It will do everything you've described and with limitless range!but speaking for the two of us, we're interested in silent cruising in our..stop! 65 HP would do everything we want to do except range.
Yeah, that's true, and a good looking boat too. While we're at it, I'd even throw in an Aspen asymmetrical power-cat design, for a single motor application. Thanks for the stimulating boat fodder, by the way.
Add a good water maker to save on the weight of stored water.
