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.

Not only is the drag of the wind turbine installation reducing your lift-to-drag ratio unfavourably, it's also added top weight, increasing heel and drift when working to windward.

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

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

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.

I had a dream, I was sailing, I was happy, I was even smiling. Then I looked down and saw that I was on a multi-hull and woke up suddenly in a cold sweat.
