My boat is pretty much a Roger Fletcher product. I built his model, read his book and had lunch with him to further pick his mind.
Have currently finished assembly of ribs, and milled all 16' Ash to size. When i manage to get my workshop up to 60 I will epoxy ribs-they are Alaskan Yellow Cedar. Trim is Oregon Ash. Stem is whie oak and transom is Honduran Mahogany.

I built a table saw jig for scarfing the ash to cut a 12:1 angle to reach the long lengths( it came in 10' length) . Epoxy seems to hold well and mill nicely. The ash was 1" rough. The Cedar came rough 1 by 6. After a good bit of experimentation, I built a scarfing jig for the plywood by inlaying a 2in metal strip from TruValue onto 3/4 ply and used Gorilla Glue to assemble so it filled all cracks giving me a nice square edge. I use an electric planer to cut stairsteps and then smooth with a random orbit sander. Worked nicely in test. Will soon start on big pieces! Will add pictures as soon as I figure out how to add them to this !
