You can use plywood for complete build, just glue ply to required dimension

I have built a OD18 and owned a FS17 really impressed with bateau's design.

Note they have a builders forum that is very very helpful if you have questions or what not. Solid little boats if you follow guidelines, but there are a lot of other good designers.
