I have access to an exceptional straight 20' white ash sawbolt that a logger who loves canoes cut for me. It's now at a sawmill in northern Wisconsin near Spooner. If anyone has a serious interest in obtaining one or more of the boards, please reply. firstname.lastname@example.org. The boards will all be light-colored sapwood and sawn to 1-1/4" x 6" x 20' and will be cut on a bandsaw rig. Should be able to get five gunwales per board. Very reasonably priced for serious builders.
