Yeah, I am worried about the trunk.The sheet cleats are a bit too far forward, nothing else strange about them. I installed some pretty close to that position a few years ago on a club boat. It used to be legal to attach them anywhere on the hull, but now you have to use the backing plates whose position is shown on the measurement diagram.
The bottom around the centreboard trunk looks bad though. It's obviously been repaired at least once before, and not very successfully. I'd sand away the differing shade of blue to see what's underneath. Good that you have an inspection port at the right place to fix the problem internally, if needed. (Maybe it was installed there exactly because of this?)

The damage looks uglier than it really is... first thing you want to do is sand away that cr@ppy attempt at repair. Get rid of those white areas where you can see the cloth weave. Only take it down as far as you need to until you find solid glass, you'll be rebuilding from that point. You may have to lay glass over the hull and into the trunk, some more close-ups of the trunk itself would be helpful, particularly some shots of the seam between trunk and hull. I suspect the earlier repair attempt was made due to a leak in that seam. An inspection port may not be necessary, I wouldn't cut a hole until you know you're gonna need it. What you might need is a good file or two to work inside that trunk... especially if you need to cover that seam with more glass. I once fixed a similar problem with my Laser hull, the older boats tend to develop leaky seams where the trunk was glassed to the hull. Not the end of the world, and a good repair job will eliminate the problem. Hey, it's a "free" boat! [As if there is such a thing, lol.] Good news is that it's a relatively small area, which will keep overall costs down. Cheers!
There is some moisture inside. I have been opening the port and closing it at night, because of potential thunderstorms.Weather looks sunny where you are. How dry is the inside of the boat? If it's been sealed up for a while I'd let it air for a few weeks somewhere warm and dry or at least out of the rain with plenty of ventilation before you add anything inside it.
