Jeff,

These are in fact the original dimensions, although a later improved version over an earlier design. The earlier design may have had thinner ply, I don't know for sure but, this one also has closer rib spacing at 3" vs 6" for the earlier design. The documentation says the earlier ones weighed 72 lbs, no word yet on this one since I've not completed the CAD work yet.

As for actual construction, I would mimic modern wood float methodology, I see your point on bending 1/4' bottom to the radius specified.

Thanks
