Firs of all I wasn't very satisfied with the companion way hatch. It turned out to be skewed a bit and that bothered me. With aluminum the solution is: cut it off and weld it again (and then straight).
So that is what I did. I ended up with a shorter hatch but that was still within the limits to be rain-proof.
Probably I'll do some rain-test and decide if I have to install a small water-strip on the back-side. With heavy rains the water should drain into the garage instead of the cabin.
