I pulled a 12' wood/glass boat (commercialy built) off of Ross lake up at Hozemine years ago. The rangers put a "free boat" sign in it. I've had it home since 2004. Did a little sanding on it with plans to repaint it and set the transom up for a long shaft 12-15 horse. I've never had it in the water since I got it home. The weekend I got it, I fished upper Ross with it with the one oar that was available. Didn't leak a drop.
