: The cross sections looks pretty close to optimum hull with little wave
: resistance. Thats just by the looks, might be different in reality. Design
: displacement on 250 lbs sounds quite much - if you are looking for speed
: you might want to keep the weight down and design it without much
: load/gear onboard. If you really are looking for speed you could just make
: the kayak longer. However narrowing the waterline would have good effect
: on speed.

: For stability side the hull might be really tippy with very little righting
: force at all. Also I don't like the swede-form at waterline - racing
: kayaks that have swede form in deck have quite symmetrical underwater
: body. The sides are just raked more at the widest part.

: Btw. De Rijp -kayak has wetted surface area of 13.6 ft^2 with 90kg
: displacement. Just wanted to check that. It's much narrower but chined
: makes it also a somewhat stable.

Design displacement of 250 lbs. I'd think would be pretty light. Assuming a paddler of 200 lbs. and a 35 lb. boat weight only leaves 15 lbs. for gear.
