After reading the earlier postings on electric engines I recalled that there was an article on them in Cruising World magazine, november 1996.
a couple on a German steel sloop 'Raroia' had a physically small electric motor that could transit the Kiel canal at low speed for 12 hours.
The system had three voltage levels: 24v for 2 knots(20hours max).
48v for four to five knots (five hours max). and 72v for six knots (one hour).
The owner who was an electrical engineer said he estimated the engine delivered around 20hp. the boat carried 12 six volt heavy duty batteries in the bilge which also served as part of the ballast.
The motor can be held in one hand.
They charged their batteries by wind generator and solar power.
The cost of the motor was US $1000 in 1996 and was manufactured in France by Mr Knorzer,Cupex S.A.

I dont know if the company is still around or whether the boat has been a long term success, but thought it interesting enough to post.
