I was told by a paddler on the Columbia last summer that Okoume plywood is available in Portland, but I have called around and not been able to locate any. Do I have to go to Seattle or Port Townsend? By-the-way of introduction, I live across the Columbia from Portland in Vancouver, USA, and built a Chesapeake 18 from a kit two years ago. Now I want to start a North Bay from plans. I'm itching to build a strip-built, but want to get one or two more boats on the water first.
