Adding a sponson to the _outside_ of a hull can make a difference. Speaking of what water "knows". If you have a sponson on the outside of a hull how does the water "know" that it is not the outside of the hull itself? Say you "glue" that sponson to the outside of the hull. How does the water know that this is a sponson on the outside of the hull rather than just a bulge in the contour of the hull. What if you are paddling a Klepper like the old one that I used to have that used an air-bag to tighten the skin and this air bag ran around the hull like a sponson. What does the water think of this? That air bag was "inside" the hull. -------------------- The reason the water "knows" about the built in sponson is that as the partially flooded boat starts to tip the water is restrained from going to the edge of the outside hull "within" the boat. The otherwise freely mobile water is constrained to stay in the center of the boat because the edges are full of air. *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
