Brian:
I bought a breakdown set of ash gunwales from the same guy and put them on a Royalex Howler and they worked great. You save a bunch of money on shipping and once they are epoxied together and sanded (lots of sanding) you can hardly see the joints. Glue was included but I used G-Flex instead. Everything is marked, and pre-drilled (small wood screws hold the joints together until the epoxy sets…..screws included). I ended up using some small clamps too. No way I could get 15′ ash gunwales anywhere by me, but the breakdown set worked well. I’d do it again.
