Hatch with flange or flat base?
Posted: Thu Dec 26, 2013 10:00 am
Happy holidays
I would like to replace the old ventilation hole-thingy in the cabin (not the head) with a hatch. I seem to remember Bob has done the exact same thing - although I can't seem to find the pictures I remember seeing I'm looking at a Lewmar size 10 ocean hatch (and trimkit). Size 10 is 32.4 cm x 32.4 cm. I'm worried that if I choose a bigger hatch the curvature of the deck will result in a big gap (>1 mm) between the deck and the base of the hatch. Lewmar has two versions of their ocean hatches - one with a flange and one with a flat base.

With one should I choose (flange or flat base)? Lewmar doesn't seem to provide much information.
