Does the same > apply to kayaks? Could be, but any hull will have some directional instability down wave, *until it begins to surf on the wave.* Then the stability normally increases, though most sea kayak hulls (I think) will not be stable straight down the wave. Rather, they will be stable to the left (or right), as you force a chine to carve on the wave. The directional instability comes (in part) from the differences in speed of the water in the wave. Check out Bascom's "Waves and Beaches" for a description of water motion within a wave. -- Dave Kruger Astoria, OR *************************************************************************** PaddleWise Paddling Mailing List Submissions: paddlewise_at_lists.intelenet.net Subscriptions: paddlewise-request_at_lists.intelenet.net Website: http://www.gasp-seakayak.net/paddlewise/ ***************************************************************************Received on Fri Oct 09 1998 - 02:14:24 PDT
