While I agree that a properly designed dorade vent is the way to go, you won't be able to design one that can take "green water" over the decks and not leak like a sieve into the cabin.
In cases where you're getting green water over the decks, you need to close off the dorades. Same thing with the Nicro vents... in cases of heavy weather and seas—you need to remove the vent and close off the hole with a deckplate, otherwise, expect some water for company.
That said, four-inch dorades are the minimum size I'd go with.. and if you can install four of them...two forward and two aft.. it would go a long way to keeping fresh air flowing through the boat. The metal dorade vents are the way to go, but you really do need to build line guards for them, as TDW points out.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
