Day 1 of testing results are in:
The inside of my hull is as dry as the elbows and knees on Candy. Funny thing is that when I had the stock round hatch I would always have a small amount of water in my hull, nothing major or even enough to be concerned about but I still had water. With this new hatch I couldn't find a drop of water...........maybe it was the 1 1/2 tubes of marine goop that I used to seal it.
