Boundary Waters Canoe Area Wilderness (BWCAW). Text. Flex-core construction creates a more rugged canoe than our Ultra-light core, and is meant for general paddling on all but extreme waters. nejones1987 04/30/2016 12:34PM. Big for solo day trips unless you're a big guy. It's a little wider than the 16' Wenonah Prospector so works well as a solo/tandem moving water open canoe. The canoe is in good condition, there are some scratches on underside as you would expect, yoke and seats in good condition, webbing tight.
