Well, Rick, I've cleverly arranged for my boat to be deeper in the water, by a 1/2 " or so, to provide more resistance to leeway. So I should need to rely less on the rudders, right?

You know I could do some math, each hull is about 10.25 sq. ft. in area. Mine displaces about 100 pounds more water than yours, or 1.5 cubic feet, so I push the boat .14 inches deeper in the water. Call it an 1/8". Wait ... there's two hulls. So now we'll call it 1/16". Crap. It's hard for me to imagine that little bit of extra wetted surface makes any difference at all. Unless there's something I'm missing. I should quit whining and learn to sail.

Crap. Nut on the end of the tiller again.
