Rolf, Dennis: one of the biggest problems I find is that the boat gathers headway almost immediatly, and tends to run over you! This is not in the extreme but all the gear (I've tried several arrangements) seems to get swept under the boat. The line I use runs the length of the hull, and is attached at both ends. So, if you should find yourself under the boat you can pull yourself forward again. Even the little resistance the knot provides for your knee is enough to overcome the boat's forward motion with little effort. Simpler is better in this case, imo.
