My new boat, which I'm picking up in Tybee Island in 2 weeks, is an NDK Pilgrim Expedition. According to this page, the cockpit is 32" x 17" with an 80" circumference. http://www.skirtfit.com/touring-a/nigel-dennis/ What size is that? I'm now super confused because when I was in Tybee in Oct I tried a Pilgrim and Pilgrim Exp and I used my 1.7 Seals skirt and it seemed fine. Now the seller of the boat tells me that my 1.7 won't fit and that I'll need a different skirt.?? One would think there would be a page that would convert cockpit size to SS size, but I sure can't find it!
