I went home and crawled around under the boat yesterday and there did seem to be a gap between the bunk board and the hull on the starboard side inside bunk, about 1/3 of the way from rear to front. Not sure if its a hook or not, but have decided to try to get it checked out if I can find somewhere close that will look at it properly. The thing that stood out that I did notice, is at the rear edge of the boat to the side of the pad. It looks like the rear edge has a lip. It could be like this intentionally, I don't know.
