Take a look at some of the recent back issues of SAIL magazine. Nigel Calder is outfitting a boat with electric drive. His main premise is that we don't know anything about the practicality of electric drive and he is gathering data. Like the electric car issue, batteries are the big problem. He has already given up on Lithium Ion batteries in favor of the Optima TPPL (thin plate pure lead) batteries.
