Re: Electric Propulsion.

Hi Terry,

I am interested in converting a boat I am rebuilding to electric. The boat is a Nantucket Clipper a 32' 7.5 ton yawl. The original diesel is a Sabb 10hp thumper. It is miserly on fuel but all owners of sister ships consider it way underpowered and typically repower with a modern 20-26hp like westerberke. I just returned from sailing on a sistership and while on a beam reach with all sails up in a light wind, she gently ran aground. We loosened sheets, started the diesel, shifted weight around, rocked over the rail and just as gently backed off the sand bar. The slightly embaressed captain looked at me and in reference to my idea about electric power said, "This is the reason for having extra power. You can not do that with your old engine or electric power."
How about that? If a boat is fitted with the proper prop and an electric motor that would rate with 20+hp diesels, would emergency power situations be an issue?
