Hello Phil; I was thinking about you when I posted this. It would be a great and doable project for someone to finish Design by oneoceankayaks.com the model is the Cape Ann Storm. The description below is from their website:
Cape Ann Storm - 17.5' x 22" ( 5,33 x 0,558m)
Fast and seaworthy high performance kayak that beginners easily tame and advanced paddlers never outgrow. Its displacement is optimized to accommodate paddlers from 160 to 220lb with enough space to pack gear for weekend trips.
Even though it is overall 6" shorter than the Cape Ann, its prismatic coefficient and the length of its effective waterline (curve of areas) make CA Storm very efficient at high cruising or racing speeds.
Its combination of low Area/Displacement ratio, high Length/Beam ratio and its seaworthiness make it a fast hull, good enough for Ocean racing. Harder chines in the aft sections give it good stability in lean and its V cross-section and balanced lateral plane make it track quite well.
If you can dish it out, this kayak can take it!
