I know at least a couple others have done a similar mod. As it is, all water that hits the hatch, whether it be from rain, waves, climbing in or washing the boat, drains directly into the bilge. Not a good set-up if your boat is sitting at the dock in a downpour. Since that is a possibility at this year's AOTH I decided to finally do this simple mod that drains this water out of the boat via a through-hull opening. I already had an extra through-hull from my raw water pressure relief system which I no longer use. I just cut and flared two small pieces of 1/2" copper tubing. I drilled new drain holes and tapered the top so the copper drains would fit flush. I cemented them in with 4200 and filled the original small drain holes with epoxy. Using hard plastic tubing and PVC fittings I cemented together a simple drain system using two part epoxy. I still have to clean up around the drain holes.
