Has anyone built a skin on frame kayak with a very low back deck? 1.5" or less rear deck freeboard? I've given up on my Tahe Greenland for the strait jacket roll. I suspect 1.5" is too much freeboard for me (the Zegul Greenland lists capacity at 220 pounds). Since 1.5 cm appears to be legit, I'd like to try something similar. All rolling kayaks must have at least 1.5 centimeters of freeboard, with kayaker seated in kayak. http://www.qajaqusa.org/QK/rolls/rolls.html And of course the other possibility is beam. My Tahe is hips plus 2 fists, which is wide for a rolling kayak. The Tahe is extremely good for rolling; it feels like it wants to come up. It is also a good blend in that it does well for both forward finishing and layback rolls. I'd like a sof that is similarly good at both. Advice would be much appreciated.
