I bought a 4 inch screw lid today and went ahead and cut the hole in the ski locker. Remember I have the playpen seating but it should still be the same basically. Water was on top of the foam as soon as I cut into the fiberglass. I then removed the foam all the way down to the bottom of the hull. As I expected the water kept coming. I used the shop vac and sucked up about 2 gallons. I am going to let it sit and go back and check it tomorrow before putting the lid on it. I will post some pics as soon as I can figure out how to shrink the file size on this new Mac Book.
