I used to have the 13' Geenoe. Had a 9.9 Johnson on it and it would scoot. The wide beam and pontoon bottom makes then stable enough to throw a cast net from. Oddly, the 15' is considered a square stern canoe and the 13' is considered a boat. Only difference is the last 2' of taper in the rear.
I'll give you $100 for it today, as it is!
Cool boats. That one will take a 15hp outboard if I'm not mistaken.
