Converting 12' Illusion to pedal-power prop drive
So I stumbled across this cute little hull that the owner was going to take to the dump. It seemed it would make a great human-powered project because of the slippery hull design.
My question is about the keel. The owner told me that as a girl she'd fill the keel with lead shot, then go racing. Now to me it seems that if I don't have the wind blowing on a sail, trying to tip over my boat, I don't need that extra weight, and possibly not all that depth in the keel. Since I'd use it on a river that rises and falls several feet each day, I don't want the hull any deeper than necessary, but I REALLY don't want to tip over. So how much could I safely shorten that keel?
The boat driver sits inside the boat with their head sticking out. Looks perfect for a twisted chain drive.
