When I read "side grading" your boat, at first I thought... "Hmm, dremd knows some kind of hull efficiency modification I've never heard of!" Then I figured it out.
Way OT, but this summer I'd like to "side grade" a little catamaran I picked up for 20 bucks a couple of years ago (minus some key components) by adding a recumbent pedal powered prop drive. Just for kicks.
(I won't jack your thread though. I'll start a new one when the warm weather comes and messing around in boats becomes possible once again.)
