Does anybody out there have any experence installing hatches on a kayak? I've read a few articles on the subject but they were more for Boaters cutting into fiberglass. I think the process will be simple enough, cut a hole, place the hatch over the hole and screw down (well nut and bolt acually), apply enough Marine Goop to seal the hatch and viola. Anybody know anthing more?
