> Any thoughts?

just guessing,again, but I would think there couldn't be very much variation in the rocker,whatever it is, since for a given beam and panel shape the boat can really only take one shape. I suppose you could vary the rocker in the ends a miniscule amount by spreading the shear but at some point I think flat spots would show up. If I was building it I would attempt to force a tad more rocker by spreading the shear in the middle or in the bow, the boat tracks very hard.
