chucklesR Someone should post it in the 'what boat is this?' thread

chucklesR Reckon it's a V-22 Catamaran

blogs.business2.com/waterlog/images/wcat_1.jpg is where I got the pic - apparently the boat can go to windward since the turbines power a prop.

sailingdog Chuckles can pivot the rotor and use it for vertical takeoff capability.

Practically correct

Chuck, I agree from a practical standpoint--you won't notice any loss of boatspeed or be able to measure it unless you are a floating laboratory. However, the wind generator prop is extracting power from the air and that is causing drag and that drag will slow the boat down.

chucklesR not my boat - not even a Gemini (tho it looks like one) I found it on the internet. Apparently the wind turbine powers an electric motor.

sailingdog Sasha-

That last chance grab rope would actually do quite a bit of good if it was connected to a wind vane/autopilot disconnect, and the boat has a bit of weather helm...so the boat would turn up. Otherwise, you become very tasty shark bait..
