A few months ago I bought my first boat in 30 years, a mid-80s Aquasport 25 footer that appeared to be clean and in good condition. I keep it in the water, and within a couple of months I noticed the boat slightly listing to starboard. That's where the kicker is, plus the cockpit, etc., so at first I thought I just hadn't noticed this slight list before, and that it was likely just due to uneven loading.<br /><br />Then the list became more pronounced and couldn't be ignored. I pulled the boat out of the water and looked the hull over. Didn't see any problems. But a few days later, when sanding the hull in prep for bottom paint, I saw water seeping out of two spots, on the starboard hull bottom (the heavy, listing side). When pressed with a thumb, these spots feel<br /> wet and soft like foam. They appeared to be spots where a previous sander went right through the outer glass. But, the outer glass is amazingly thin in these spots. An old patch, maybe?<br /><br />I don't know the hull construction of these boats. Is it solid glass, except for narrow foam and wood stringers? Or what? And what do you think is going on here? How big of a problem might I have?
