I was at Trawlerfest this weekend in Stuart and spent some time talking to the Island Pilot rep about their new hybrid trawler - maybe the wave of the future if fuel costs continue to escalate?
It's a 40 foot catamaran hulled cruising boat powered by (2) 35hp electric motors, powered either from a 6kw photovoltataic array and/or a pair small deisel generators. The solar array delivers sufficent power for a 6 knot cruise using no fuel at all, and the generators supply additional or subsitiute power for a max speed of 13 knots - as fast as most traditional trawlers, with fuel efficencies averaging 14 NMPG.
They didn't have one at the show, as the prototype is just now undergoing sea trials over in China. Looks like prices will run around 500k http://www.dsehybrid.com/
