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.
