How powerful a wind turbine do I need to recharge my electric boat?
I am building a two-seater, electric catamaran, 21 ft. long, about 8 knots top speed, no sails, just two electric DC engines. I am aiming at a range of about 20 miles before it needs recharging, and my only recharging device will be a wind turbine. I've seen they do about 100 - 400 Watts when they are the marine type which usually attaches to sailboats; how long would it take for such a turbine to replenish energy in my boat, would anyone know? I'm hopeless with these things, but I still love doing them.
Thanks so much!

you'll never get it high enough to work with regularity in a boat without sinking it in a storm.
