: I sold last season's Sea Rover,

Dave, I have framed up a Sea Rover to build strictly for rolling. I've used 1/2" ply and used WRC for all longitudinals. I followed Tom Yost's recommendations for the scantlings. It all goes together as advertised. All considered, I'm a little concerned that there is too much sag and spring in the boat due to the lightness of the gunwales, chines and keel, especially with the WRC. I saw on Tom's site another design with a rather heavy person (not me, I'm only about 155#) and the stern was actually completely out of the water and the boat looked like it was sagging significantly.
What was your experience with the Sea Rover along these lines? I cannot imagine the skin adding that much longitudinal stability in the frame, but then again, this is my first skin-on-frame attempt.
Cheers and happy paddling, Wil.
