I believe vents, with proper dorades are more for air circ while the boat is
sitting (in the slip) with all hatches closed.

Certainly a lot have vents - my Nonsuch did. The PDQ doesn't have any,
but it
does have 8 large horizontal hatches, plus 8 side hatches. I think the
early
boats were short on hatches, so they went around poking holes wherever
they
could.

don't most cruising boats have vents. I have 2 cowl vents.

That means
hatches were probably dogged.
Hatches are always sealed when a sailing boat is underway.
Wow, your crew must suffer on a hot day. There are lots of boats, and
lots of
situations where its desirable and permissible to make way with a
hatch
open. I
would say that 90% of the time we have a saloon hatch open underway,
weather
permitting. Three of our hatches (2 in the galley, one in the head)
have
been
cracked open for all but a few hours in the last 5 years.
IIRC, the Tartan 37 has a hatch just forward of the companionway that
could be
left open in moderate conditions.
