Props Sail Boat
Is ti possible to have a 100% electric driven sail boat?

How ? effecient solar power? Battery driven props?

Mostly stupid answers.

It's already been done and Capt. John is bang on the money with Solomon Technologies.
There is a Lagoon Catamaran and a Tartan mono-hull with Solomon power. These motors can recharge as the prop freewheels under sail. Of coarse, there are solar and wind driven recharge systems on board as well.
Battery weight is only a minor concern and often overcome by reducing keel weight. At the very least, the batteries are placed low and central where they assist the righting moment of the hull. There is usually a separate bank for house(on board) power and motor and winches if so equipped.

So yeah...here in 2008, this is not new. Certainly it is fledgling or emerging technology...but not new.

Expensive?...you bet!
