I just decided to place the thicker ones aft. I was able to place the thinner ones over 2/3 of the boat. If I don’t intersperse them, you shouldn’t be able to note much difference. I also spaced the frames farther apart toward the rear. Trying to conserve wood. The instructions for the 26” boat says to space the frames 3/16” apart. The instructions for the 16” boat say 1/4”. It doesn’t make sense to space them farther apart for the smaller boat. The instructions probably should have said 5/16 instead of 3/16. Also, the stringers are said to be 5/16 down from the gunwales on both boats. I think on the bigger boat my math says it should be more like 1”. So I think I’ll set it there. I’ll use the sapelle for stringers. The original boat had a mixture of oak, fir, cedar, and terebinth or whatever scraps they could find.
