Has anyone tested the >resistance of different hull designs to slide-slipping? I timed myself over a short distance while skulling various kayaks sideways as fast as I could (for 20 to 30 seconds). I think your guess is correct about hard chines, the sides are more vertical and if you lean the kayak you dig the chine in deeper increasing the size of the underwater profile. I tried long boats and short boats, hard chined and round bilge boats, narrow and wide boats. My goal was to beat Olympic gold medalist Greg Barton in a short fun race at the Port Townsend symposium that had a backwards and sideways leg. If you want to go sideways faster go with round bilges and a wider kayak. Length didn't seem to make much difference. The added length may be being made up for the by the shallower draft at the same dispalcement. Most important though is to find a kayak with the center of lateral resistance at your side so the kayak will go straight sideways rather than yaw (so the bow or stern takes the lead). Yawing in this situation is very hard to correct for. It would seem as >though this may an important factor in "real-world" performance.
