this is an older (1987) regal sebring 19 ft fiberglass. Bought the boat on the trailer, and launched it in june. Today i had a walk around out on the sandbar and noticed a (very) loose bow eye bolt. The fiberglass is not damaged, but it is hanging out at least an inch farther than it should be. plenty of exposed threads. I have no idea how these are re-enforced, but there are two nuts on visible on the eye on the front side, should i just tighten these down or should i see whats going on behind it? I actually cant see any way to access behind it in this boat (bow-rider). I'm just worried the backer plate/nuts have come loose. Really don't want that snapping free while i'm winching it up
