Again, I don't know Charlie Wilson's methodology, but as a close friend and collaborator of Dave Yost, I suspect he has the exact LWL and BWL for many of the Yost designed canoes, which number over 100 and include most of the Curtis, Bell, Placid and Swift canoes.

I am heartened that Yost, and his son, are still at work, and designing some canoes better suited to super-sized paddlers.
