Hello, and
to the boards.
If there is some standing water on the hatch it may leak around the hatch lid/frame meeting surface or where the toggle hardware goes through the hatch itself. If it leaks where the the hatch frame rests on the deck surface, the frame may need to be removed and resealed, or it may be warped a bit. I'm not sure where you're located or whom you purchased it from, but I was at OEX in Seal Beach today talking with Andy who runs the store now, and I'm sure if you called or ran it over there and let him look at it he would treat you right. Hope this helps,
Perry
