I busted off my otter boat during the niagara wave fest . I use the amish outfitters line and like it, however, in my instance the knot at the otter pulled out, breaking styrofoam around the retention holes. Very poorly engineered. I kind of knew one day it would happen, and as luck would have it, what ever might go wrong, usually goes wrong during a tournament. For a quick fix all I had to do was reverse the boards/keels/holes and use the holes on the other side. Seems like there should be a stainless backer plate behind the styrofoam and ahead of the knot. Something to do in the offseason.
