There is NO WAY the paddle has enough buoyancy to provide the same platform as the side of the pool. So I can't see how a paddle can provide the same point of leverage. The force to drive the kayak under the water has to leverage from somewhere. Building up some speed would help, just like a bow stall, but that doesn't answer how people can get on end from a motionless position with a single stroke. Doing it at the side of the pool reveals the forces involved, and I just don't get it. When I get the paddle shaft level with the water, and commit, and get the kayak up to 90 degrees on edge - the paddle dives and I simply roll. The nose or tail get up _maybe_ 45 degrees, but that's it.
