Before you go to the extreme of wet sanding, in case it is Poliglow, buy a quart of Poliglow stripper and a Scotchbrite pad and go to it.
Some years ago, I bought a 34' sailboat that had been coated with a Poliglow competitive product and really looked bad. I bought the stripper and was able to strip the entire boat in less than an hour. Whole lot easier than wet sanding an entire 34' boat
That's the name I was trying to remember! Basically the same idea though. They had a booth at the boat show trying to convince people with a decent sized boat to spend $10K for doing just their hull sides. Their selling point was that you wouldn't have to polish again but for that price I could have someone else polish my hull sides and have it looking perfect for 20-30 years considering it doesn't have to be polished every single season. The product does have a place under certain conditions but it would be a very low option on the list IMO.
Before you use any stripper, make sure the surface is gelcoat and not paint. I have more confidence that gelcoat would hold up but paint might not. Depends on what was used. You also don't want to stain the gelcoat permanently so it may be best to test a small inconspicuous spot and leave it for a few days to see if there is any reaction to the top coating.
Keep us posted.
