PVC was bedded and glassed to the bottom of the hatch gutters. Now I can router as many drain holes in from the top that will allow the hatches that will be bone dry. The PVC will go to a hose that will go to a sump box in the aft bilge. All gutters and drains will be plumbed to this sump box so the bilges will stay bone dry. The sump box will also have a valve that will allow it to be used a a backup emergency bilge pump.
Note, I hate building gutters and hatches to a happily paid Jim Wells to build them for me.
