Basically, it's a boat with a windmill on it.
No, it's not perpetual motion, it's just another way to use the speed difference between the air and an object floating in water.
The wind turbine has a device to keep it pointed into the wind. When one sails into the wind, one's speed is added to
the wind speed, and the turbine generates more current. And vice versa.

Don't know how stable this thing is, however someone's done it. [skinflaps, Jan 25 2007]

Put wings on it and take off. |

I think the power generated that way wouldn't be enough to power the ship. And the increased drag on the windmill flaps would contradict the propulsion generated. A windmill could help the main engine, but not serve as primary propulsion. |
|
| |
But that line of thought is valid; there is talk of creating giant drag parachutes to pull tankers, supplementing the on-board engines. In good wind conditions, this would save up to 20% on the fuel. |
|
| |
I had a similar idea to yours, only it didn't involve the electrical part, mechanical transmission only. The windmill would be connected to the propellers via a gearbox. |
|
| |
Objectively, your idea deserves half a bun, but I'll round it up [+] |
|
| |
I believe they're thinking or are doing this with barges.Also some guy has designed a catamaran with a verticle wind turbine held within the deck. |
|
| |
That "Revelation II" link is exactly what I was talking about. |
|
| |
...aaand, it's been done. I feel deflated now. |

the way you describe it is a PMM If you were using the wind to propel yourself you would generate less power as the wind would be coming from the rear of the boat. If you were powered then you would use up slightly more energy for every bit you generated. |

If you were talking about something like the revelation thing then this is Baked. |
