: I have the materials to build a wooden frame Yost Sea Rider and I

: gunwales 1.5 x .75 inch
: 2 - 20 ft

: keel chine, deck stringers 1 x.75 inch

: 17 ft keel
: 2 - 17 ft chines
: 12 ft deck stringers (2 - 4 ft, 2 - 2 ft. ?)

: I need to scarf the longer pieces up so it would be helpful to be
: more certain of the lengths I will need, but for the
: life of me, I can't find the reference now on yostwerks.com that
: cites 20 ft for gunwales, 17 feet for keel and chines?
: Or did I just make that up?

Well, your dimensions are correct - except for the lengths. It's a 17 ft, 3 inch design, so you'd only need 18' of gunwale length, which will still give you some left over material. As for the keel, depending on the length and angles of your stems, you'll only need a piece 14 - 15ft long. Your chines can be 16-17 ft, again depending on your stems.

Also, if your boat ends up a few inches short or long, that won't matter at all . . . .

Good luck!
