Ron, have you ever gone to a "brain storm session", we used to have them at Apple all the time and you could throw out any thoughts that came to mind. This idea isn't so far fetched at all, it just needs room. I may be a little of a maniac but I have 4 sailboats from 17 to 37 on deck so it gives me a wide range of test platforms, love it... What does and old retired, tired inganear do? He works on projects... chuckle Who said we have to stay conventional?.... out of the box thoughts are accepted, at least by me.. chuckle... if you have a chance take a look at the Redeemed album, needed a total rebuild, it would have been a reef if anyone else would have got her... Dave K
PS: if anyone is looking for a perfect platform for a slippery electric sailboat conversion that is a solid boat a friend of mine has one. James Baldwin has an Alberg 30 on a trailer in southeast Georgia that would be perfect, all the rigging and sails, just needs the interior and what ever auxiliary power you want to put in it.. I believe he has it on his web site www.atomvoyages.com

Dave, Sorry if I posted out of context, it was a flash of mechanics and no thought of restrictions of the present hull.
If it has any value at all, it might require a complete new boat design to make it practical.
