I'd patch the holes where the mat is showing with the Fasco stuff Chuck recommends to keep water out of the laminate. I've used it on my bottom painting project and it seems to be about same hardness as gel coat, so it sands easily.
I'd follow Hermco's advice on cleaning the gel coat with bleach to eliminate the black spots. Then check out this thread on
Polyglo . . . it's MUCH less work than the wet sand/compound/wax option and much more durable! Use their cleaner (full strength if necessary) along with the 3M scrubber that comes in the kit. The gel coat will then look very dull, but you will be amazed at the gloss the coating will put on it.
I've had my boat since 1975, and never waxed the cabin top because I didn't want kids slipping on it, so it looked about like yours. However I haven't had kids up there for a long time, so I tried the polyglo on it 7-8 years ago and was amazed at the results! I'll never use wax again! It's not cheap but sometimes you can find better deals on it at boat shows.
