Deck hatches for US-made 2002 Oceanis 311

[cosmonaut]

I'm trying to identify the replacements for the two Lewmar deck hatches on my 311. I measured approximately 19.5" x 14.5" to the outside of the flange (both are the same hatch size). But the Lewmar site's chart doesn't have anything of that size. The closest is the low-profile size 30, but that seems a bit wider than what I'm measuriing. Anybody know?

Have you called Lewmar? I have found their tech staff are very knowledgeable and helpful.

If not Lewmar, check Bomar. You'll find the ID on the underside :

I have both Lewmar and Bomar on my boat and they are almost identical.

I would chose 30. But what do I know. My logic suggests that maybe your measuring the over hang that protects the seals from waves.

They should be Lewmar low profile hatches. Examine the lens thoroughly for inscribed size data on the edge of the acrylic lens; sometimes you have to push the rubber gasket out of the way to see the inscription. You can also see the sizes on the Beneteau Spare Parts website.
