hans, I'm the one that started this thread and what you are describing is the issue of this thread (at least the original issue). As far as I know, there are only 2 ways to fix this: 1) make a hole in the locker floor and install a deck plate so that you can periodically shopvac the water out, or 2) make a larger hole in the floor, dry it all out, then reglass the floor and the very front of the locker floor where the water enters that space. I had option 2 done under warranty and so far I haven't noticed any water in that space since then. But the total bill (paid by SC) was well over $1,000. If I get water there again, I will likely opt for #1 as it took them 10 days to get the work done (lot's of time just drying out the boat), and it could recur. It looks like they did a really good job, but the shop and I both assumed we identified the source of the intrusion.

If you step and bouncing in the locker, does water squish out the very front of the locker, or have you figured out how it's getting in there?
