After years of messing about in pedal kayaks, I decided that what I
really wanted was a much narrower main hull with one outrigger. That
gave less wetted area, and having the drive leg beside the main hull
made it easy to swing up for beaching or weed removal, etc. while
also keeping the drag and thrust lines close together. The ama gave
the option of carrying a passenger without ruining the trim, camping
on the tramp, or sailing, with water ballast on one tack. The open
cockpit is self-bailing except for the footwell, which can have a
speed bailer. I have the hulls for this built, 20' and 12' long, and
most of the hardware for a SpinFin with S cranks on one side, but
have no time to finish it now. Interested?
