Some boats have both. We do. Or we can just suck out depending on what we want to do.

Yup. Plus after you live in these parts long enough you tend to get used to it, believe it or not. :-)

I like how you northern folks chime in with the DC fans! You obviously have never spent any real time in the south. It does not help to blow 95 degree air in your face.

Thanks, appreciate the tip.

Windmill's got a good point. In our case I'm only thinking about improving air flow from outside up until the time our temps and humidity mandate genset and AC.

There are generally two hoses for blowers. One which is an intake going low into the bilge. The other is connected to the blower and forces the air out. If the intake is close enough to the exhaust this might be the CO2 issue. On our last boat it was 6' away and was the culprit.

When I lived on my sailboat in Ft Lauderdale back in the 80s....none of the boats near me had air.

My poor man's air was a cool shower before lying down, towel off, pull the damp towel on me....by the time it dried it either fell off or I pulled it over me as it had cooled off enough to need it.

That was Ft Lauderdale...not sure if it would work along the gulf coast...or inland...my 5 years between Pensacola and Mobile reminded me that hell will be a cakewalk, the humidity is a lot lower....

Very true, fans in a hot boat just move hot air around. Has anyone tried a rooftop rv type ac? I hate like hell cutting a hole in the roof but my partner hates going out in the summer, too hot she says.

You can always make one of these and put in your stateroom.

After Hurricane Hugo in Charleston, my house was destroyed so I bought this old Harker's fish boat to live on. Working as a nuke engr in the shipyard, I got put on nightshift. This meant sleeping on the boat in the daytime in SC in the fall at Shem Creek. No AC.

Could not sleep at first. Too hot. Finally got so exhausted after a few days that I simply passed out and slept in my own sweat.

Ever since then, I have been able to sleep fine in the heat. Even if sweating.

Pretty hard on the bedding.

But if I have AC, I'm gonna USE IT!!!!

Those 02-cool fans are pretty slick. I've put USB Power ports all over the boat. This model might be the hot ticket!

In the 80's I was spending time in deserts and tropical islands in my early 20s with no AC in the USMC, but I'll be darn if I'm gonna do it now! Genny + AC = Sleep

I never slept in a tent in the desert that wasn't air conditioned. I knew there was a reason I joined the Air Force.

Y'all had good chow too! Spent a lot of time on Air Force bases and ate like a king when we were there.

They were pretty good. They really put in a lot of extra effort during Thanksgiving and Christmas.

We've talked about perhaps spending a night in a tent one day, but never done so yet. I had friends in Scouts and the they'd camp out sometimes in awful weather. I never quite grasped why they did that. lol

You don't know what you're missing.
I've camped out in snow caves we'd build while backcountry skiing in Canada. I love it, but we all get our thrills in differing ways.

Indeed , the best that can be done for comfort is to lower the boats internal air temperature to the temperature of the water.

IF this , with a small fan, is enough for comfort there is no need for a noisemaker.

A good deck wash of high volume at sunset can cool the hull, screens can keep out the bugs , and a small fan can circulate a bit of air.

During the daylight only a complete sun cover , with side curtains for early AM and late PM is all there is.

The standard in the Carib.

As most noisemakers are $5.00 to $10.00 per hour for all costs , for most a marina slip at $5.00 a ft would be cheaper than anchoring out.

95F stinks , but 80F with a fan is fine.

That's funny! I have a friend who says the same thing about sleeping on a boat. When talking about my cruising plans, he responds that his idea of roughing it away from home is to go somewhere that doesn't have a Hilton or nicer. Different strokes for different folks.

When my wife and I are the only ones aboard, we cool only the main cabin aft in the evening. Several years ago I bought a 5.4K BTU window unit for $110 and mounted it in our aft companionway hatch for use on those sweltering summer nights. Our little Honda 2000i, mounted on deck, provides ample power for it all night on 1 gallon of gasoline, simultaneously powering our refrigerator and battery charger; cool and cheap compared to our 8kW genset which burns about .6-.7 gph.

Florida boy here... I've lived and boated on the coast for all my life and you do get acclimated to the heat/humidity (I'm amused by my northern friends' perception of hot as they are of my perception of cold). Anyway, ventilation and wind-scoops work very well at anchor--make sure to use screens to keep the no-see-ums and mosquitoes out. Dress lightly at night and use light weight sheets. Fans help with the circulation but seem to turn the cabin into a convection oven on really hot nights.

I have A/C on Sherpa and contemplated a small Honda generator but am averse to noise on a small boat.
