Just received the plans from my uncle for the Calkins surf dory. They're pretty complete... got all the offsets, profile and plan views with hull dimensions; sizes for the chine logs, bow and stern post. What I don't have sizes for the the frames (how thick, how wide). The boat is 20 1/2' by 6 1/2, there are 11 frames spaced on 18" centers. 1/2" ply for the bottom, 3/8" sides.
Also, doesn't tell me if the offsets are to inside or outside of the planking. My guess, looking at the plan view, is to the outside. If I err, to which side?
Even includes plans for constructing a trailer out of 2X6's. Kinda gawdy looking, though.
Got a couple more questions about the motor well, but plenty of time for that.
Thanks millions for any help you folks can offer.

Calm down! The missing parts dimensions can be guessed at with a little directed research.... at your local library. Go and check out John Gardiner's book on dorys or Ed Monk's book entitled "How to build Wooden Boats" or any one of a number of classics. Many of these books have complete plans for boats of a similar size and utility so that it would be a simple matter to compare and get an idea as to what size to make the frames.
As to lines themselves, usually the lines to a boat plan are to the inside of the planking (unless stated otherwise). This is so that the lofting of the stations and the frames can be accomplished.

I don't know what they specified in that boat, but depending on what type woods you have avaliable, 5/4 Honduras Mahogany will work and hold a nice finish. If you can find some clear and decent grain White oak in your area, 4/4 might be fine in that. It will check sometimes and harder to hold paint.

Stupid me. If I had just taken a bit more time...
Plans call for 3" x 7/8" frame floors, 3" x 7/8' ribs tapering to 1 1/2" at the sheer. The plans specify fir for stern/bow post and chine logs, no mention of type of wood for the frames (I read the whole dang sheet this time). Guess I'll see what's available, but I think I like your suggestion for the Mahogany, Oyster. Glues better than oak, doesn't it?
You were right also, Puget, about the planking. A quick email to my uncle confirmed (I'm surprised he remembered) that the dimensions were to the inside of the planking.
Thanks for the help. I'm gonna need a lot for this project.
