Hello Dan,
Also check Dupont's manual on Kevlar and you will find that it is 1/3rd as strong as fiberglass in axial compression. You have to use Kevlar very carefully.
Years back when Kevlar first came out, some C class cats and other custom one offs were built with Kevlar composite hulls. They all failed on the compression side of the hull. The bows came together. Kevlar is great stuff but you have to be careful how you use it.
