: Bill - we seem to be on the same page about a lot of things. I plan to use
: full-length plywood on the insides of the hulls, covered with fabric, with
: lightening holes in the ply (not present on the model). The ply will be
: straight bow to stern, but with a slight camber in the vertical plane to
: help tension the fabric and keep the ply straight. I hope the epoxy fillet
: method works, it will help with the weight. And I do expect to use three
: beams to connect the hulls, perhaps with a aluminum core if needed - box
: beams in front and behind the sliding seat, with the dive foil acting as a
: cross beam at the bow. I'm going to mount the beams above the hulls, not
: through them as shown below.

Hi again Carl,

Did a rough calculation about the plywood insides, using 4mm okoume, without lightening holes the ply itself would weigh nearly 30 lbs. for the two inside edges. Too much.

So, guess I'll work on a redesign using only stringers on the inside as well as the outside. SOF using Tom's designs can be very light, this design with 4 sides instead of two should be slightly heavier I'd think, but should easily be able to be in the 30 lb. range if you're careful.
