JBASS - we had the same worry. As you have probably seen on lots of the builds, I would definitely recommend supporting the hull with 2x4's horizontally. We had 3 supports on until we finished re-coring the hull sides.
In regards to shear, my brother noticed this before taking the cap off and we drilled in 2x4's on each side running lengthwise from stern to about 7' or 8' forward. This is where we saw the most shape. Where the shape changed a gap was created under the 2x4. Then then put a separate block in to keep the cap flexed to match the shear and screwed all together. If you go through the pictures you can kinda see what i'm talking about. 2x4's were mounted on topside between the 2 aft saw horses. I'm not sure this is necessary i haven't seen anyone else do this. The cap had some flex after re-coring but now that is resting on the hull pretty solid. Hopefully someone chimes in that has done full re-core on a flat cap.
The cap isn't fastened yet. Will fasten with screws and probably tab a couple spots. One problem, STBD side around mid ship, the hull sucked in a little more then we wanted. Solution TBD. Other than that seems to fit nice.
Cheers
