Woodman, I just have to ask. The lashing on the bow stem piece looks like it wouldn't withstand a lot of abuse. It looks to me like one, good bashing of the bow into a stump or something, would tear it loose from the longerons. Now, I'm betting that I'm wrong in that assessment, cause it looks like you know what you're doing. Are there other fasteners I'm not seeing? Or, is that lashing stronger than it looks?
A few years ago, on a baidarka forum, some guys were waxing enthusiastic over a "bifurcated bow" and how it was maybe hydrodynamically more clean than a standard, shaped bow. When I see your boat frame there, I realize that all someone did was reverse the bow stem piece and lash it into place. Only two functions I could envision for one of them was "A." maybe attract a cute gal in their camp, or "B." scoop up the top of fishing nets laid out in a semi-circle and concentrate fish in the nets.
