Upon inspection after winter storage, I noticed that one of the stern cleats is a little loose. It is the starboard side cleat and there is no access to the underside of the screws. I am wondering how this cleat is attached (there are two screws through the top), but I am guessing it is simply screwed into the deck, not through bolted with a plate and nuts on the underside. Who has a plan for the best fix for making sure this cleat is tight and doesn't allow water in? Thank you in advance.
