: I've been playing with a surfski design at 20 feet long. Just for
: fun I shortened it to 16.5 feet (to sneak into a local race in
: the "recreational" class)

: According to Kayak foundry the drag is nearly identical in my
: target speed (6 knots) and the drag is far less at speeds under.
: I'm not surprised at the the lower speeds, but I would have
: thought that the 6 knot drag would have been significantly
: higher.

: The stability took a huge turn for the worse... but I can live with
: tippy.

: Am I missing something? In the real world, can I take my surf ski
: plans and build a shorter ski and eat my cake too???

Part of the problem is that the 6 knot target speed is pretty slow for a ski. If you increase the speed the drag numbers change very quickly.
