Are you primarily concerned with heat build up when the boat is closed
up at the dock? What sort of "passive" air circulation do you have?
Do you have any of the Nicro solar vents or dorades to circulate air?
Is your companionway sliding cover solid or lexan?

I currently don't have a solar vent or dorades. I may add them this season. The
sliding cover is lexan.

Ouch. I'll bet your boat does collect heat. Those "day/night" solar
vents are actually quite helpful at moving and circulating air. I
have had those on previous boats and thought they were great. The
only issue is where to place them. I see more of them installed in
hatches than anywhere else. The only downside to this is worrying
about "drips" over the vberth while sleeping I didn't find that
mine was prone to dripping, but it is something to think about.
Besides, if you cover your hatches to keep the heat and uv out, a
hatch installation wouldn't work all that well. My current boat has
an ample number of dorades/cowl vents, so I am in good shape in that
area.

I would try to attack both fronts. Add some passive ventilation and
try and cover/insulate your ports and hatches. Your companionway
slide is a *big* source of your heat, I would bet. Mine is also
lexan, but I have a companionway cover that covers the whole thing.
It snaps in a couple of places along the cabin top and then hangs,
with weight, to cover the drop boards. That keeps the sun from
beaming down into the cabin.

Bob,

Add some nicrovents. At the very least, one in the forward hatch and maybe one
in the small hatch over the head. They make a HUGE difference in comfort.

Yup...I'll hit BoatUS as soon as some new coupons show up! I'd like to put a
dorade or two in...but I'm already doing a lot this spring. Have to see what I
have time for.

I'll probably install in the hatch. I've never cut into a hatch before...it's
original and is crackled with age. Maybe I'll be forced into a new hatch when I
try to cut...?

I doubt you will have a problem. When I installed one years ago, I
was able to use a jigsaw to cut the hole. I believe there is a hole
saw that is the proper size for this task, though, that would make for
a much better cut and easier job. Nicro used to make these available
on a loan basis, but things may have changed. If your yard has one,
perhaps you could borrow it or just bite the bullet and pay them to
drill the hole with theirs. The hole saw would be the way to go.

You get 2 fan blades with the Nicro. Use the exhaust. They are far
more effective in exhaust mode.
