I've decided on the overall dimentions of the SOF. 18'3" length, 20" beam, 3" gunwales. I don't mind low initial stability but I want good secondary. I want a fast seaworthy craft that is easy to roll. Low rear deck but not too low (maybe two inches off the water). I'm 6'1" and 185lbs.

Cunningham says to set the gunwale angle to 73 degrees (17deg from vertical). I paddled a SOF I like with gunwales set at 22 degrees from vertical. I've read accounts from builders setting them at 25. Now to the questions: How does the gunwale angle affect performance and stability? This is my first SOF... In terms of gunwale angle, should I follow the instructions or do my own thing.
