I'm in the planning stage as well. This looks like a 1000 hour project so realistically, I don't see getting to this until retirement ( 6 years from now). I have purchased the GA plans and the Tolman book and I have been studying. If nothing else, I've learned some techniques that I can use in my other wood working projects. Because of our property in Toledo, Oregon (on a hill) ingress, egress and storage location is going to limit the boat size. I might be able to get a 25 ft boat into my backyard. This summer I plan to mock up a trailer (out of scrap wood/ scrap axle) to see if it is possible. I've scaled it in Autocad, but nothing like to mock up to prove the concept.
Currently I'm outfitting my 19 ft Alumaweld Stryker for near shore fishing off Newport, OR. Building a bow cover with plywood, epoxy and fiberglass, installing spare battery, radio, chart plotter, and second bilge pump. I know it isn't an ocean boat, but it will work on the right days.
