I've often found myself stuck on one or two rocks with the water going away and just ended up with a bad scratch. I think for most boats the initial failure would be near the cockpit, not near the supports. Some boats might fail at the hatches. As you say, for the worst case scenario the support should be as far towards the ends of the boat as possible. > > I still believe skin/frame construction per se isn't an issue for surf > use. I agree, but for every strong kayak, there is a wave that is a little stronger. It is up to the paddler to stay on the safe side of that wave. > It would be interesting to run a test as you propose between plastic, > skin/frame, fiberglass, plywood, and woodstrip boats having similar > shapes, and similar weights to see how they hold up. But I'm not about > the fund that experiment.... Yea, a good test should bring the sample to failure so you can compare the required load. While it would be a great time to perform the experiment, I would be seeking funding from outside sources.
