I think the propulsion comes from a propeller (mast-mounted) that doubles as a windmill. |
|

That's going to have to be one wiiide catamaran if a single power generating windmill/propellor is up top. Have you thought about mounting 1000 tiny multicoloured pinwheels to the mast instead? |

Typically, windmills make lousy propellers, and propellers make lousy windmills. I'd use a water-propeller instead to move the thing for efficiency reasons, but keep the wind generator. Perhaps it could be one of those vertical wind turbine deals that rotate around a shaft. |

The trick with little catamarans is that you have to be able to switch sides in a hurry when you tack, so you can't afford to get tied down in alot of human- powered mechanics. Weight distribution is critical to speed and stability. |
|

Let's see, start with an old catamaran like my dad's, say a 16 foot Hobie. They're easily handled with 1 person if the wind isn't too stiff. But if you want human-powered, you'll need a partner, since minding the rigging and tiller can keep you pretty busy. |

I'm trying to envision the cockpit for the human-powered section of the boat and not coming up with anything good so far. Since you need to adjust your body position to the wind all the time, the human-powered mechanism will need to float on a track of some sort; perhaps a wing seat with pedals that pivots and travels as needed.
A typical catamaran's hulls are too narrow and to sit down into any hollow part into them, so you'd need to make your own hulls from scratch. |
|
|
Actually, your best bet might be a tri-hull so that you could run a central propellor and have sufficient stowage. |
|
|
[RayfordSteele], if the boat's human-powered (or anything else-powered), why would you need rigging? (Probably a dumb question; excuse my non-nauticality.) |
|
|
Could you in addition create a sunshade out of photoelectric material to suppliment the charge? |

This is amusing. I was working on this idea back in 2002. Here's a thread I started on an online forum for boat designers and builders:

If I had the bucks I would have had the prototype built by now... |
