Jeff, I am an advanced sea kayaker,160 pounds, and have paddled various sea kayaks for many years on the Great Lakes. I read your book - looked at all the kayak designs on your web site -- and am impressed with the detailed thought that you have put into your SOF kayaks.
I like the multi-chine LONG SHOT, but am really looking for a kayak about 17' x 21" wide, lower volume (lower decks front and back) with minimal rocker (to minimize impact of side winds, and eliminate need for a skeg or rudder).
Have you considered making a narrower, lower-volume version of LONG SHOT? I would be interested in buying full-scale plans for a kayak like this.
