I knew when I designed the back hatch, that it was going to be a weak spot as far as waterproofing goes.
Well, it's been raining for two days now, and I have water in my galley. I have the hatched sealed with both butyl and silicone, and the leak is coming around the door, not the frame. The factory gasket is pretty wimpy, so my first attempt at fixing the leak will be to replace that gasket with something heavier.
I have already drilled two weep holes at the base of the frame so water won't collect there. If the new gasket doesn't work, I'm trying to come up with alternate plans.
The interior is totally dry, so the roof vent, windows, and entrance door are all functioning perfectly.
I'll post some detailed diagrams if the new seal doesn't solve the leak so I can get some input from everyone on possible solutions.
