I am a Florida boy too and when growing up, air conditioning was rare. My parents first house didn't have it and I lived there until about 12. Remember going to camp in Osteen (central FL) for 4-6 weeks at a time and lived in bunk houses without air. Man, it would get hot but we got to swim twice a day in the lake and that made it tolerable.

But after working 40 years in air cooled offices and spending three summers up in MI, my body has succumbed to Northernitis and will no longer tolerate the heat. Fortunately, it is rare to need A/C up on the Great Lakes although our boat has A/C.

Any recommendations. Before I buy, how do some of you beat the overnight heat?

To me it is all about shade glorious shade and lots of fans. With our awning over the bow and the bimini over the FB the temp inside the boat stays the same as the outside temp and with out AC that is the best you can hope for. We also removed two fixed port windows and installed opening hatches which helps the air flow alot.

On the really hot nights we have a 5500 btu window AC that we put in one of the hatches and fill up the Honda 2000 which runs it at low idle. We turn it on when we go to bed at 9 and it runs till about 4 or 5 in the morning before running out of gas. The boat cools down enough to sleep comfortably. We rarely run the AC during the day. If it is that hot then that means it is time to swim, snorkel, clean the waterline or come up with some other excuse to get in the water.

We put the AC in this hatch when it is needed. We had a boot made that goes around the AC unit and snaps to the boat to fill in the rest of the port. When not in use or underway the AC is stored in the hold.

Actually it can get better,

IF your hull is solid glass under the waterline a very small fan can lift bilge air (outside water temp) up into the living spaces.

With practice in a slight breeze, enough hot air can be sucked away with port openings that, the cool air can rise to the lowest window opening.

And that is as cool as you can get in silence..

You need to spend a summer in SC where the water temp is about 90 degrees.

good point!

I bet they slept on deck as much as possible. It must have been pretty stuffy below decks in that steel can.

They also didn't need gps, the internet, a phone, email, 401k, and trawler forum.com. I personally like the forward progression mankind has made in life and would like to capitalize on it .

Too hot and humid in the South. We run the genset and 4 AC units, 68 feels good. I justify the cooler than normal temp as my generator tec says to load the generator up.

I am sitting here, at anchor, watching the morning news on TV, drinking coffee while reading/posting on TF. Yep the A/C's are on. I am anchored in Lake Charles surrounded by oil refineries. Now anchor me offshore in the Bahamas with a nice breeze blowing and I probably would not have the generator on. However, after spending all this money for a boat with all the modern conveniences, I think it's nice to be able to choose. These are pleasure boats after all. For those that want to go the simplistic route....my hat is off to you. That is why we have camp sites and hotels, it's a matter of choice.

Indeed , but simplistic route folks in the anchorage or downwind, have the limited choice of leave , or button up , spend $100 a day on a noisemaker and breath canned air.

While being considerate of others is a given, I am fortunate that if you can hear my generator, you are anchored far to close. I have no idea of your cruising style FF but have seen your house and boat and neither looked like you rough it

Wow! I complain to my wife if the house A/C is below 76--too cold for me! My home A/C is kept at 77 or 78 and is quite comfortable (at least to us thin blooded Floridians) and keeps the A/C from running all day. I have a 5000 BTU A/C on the boat; but without a generator, I only get to use it at dock. My 38 years living in Florida must have turned me into a lizard!

There have been times that we have been anchored during the summer and need a blanket during a windy night--we joke that the wind scoop will blow us out of the boat!

Sleeping on Sherpa is more of "camping" experience, which I enjoy; but I'm sure we'd be running the A/C at anchor if the boat had a generator! Maybe that will be the next upgrade?

I finally got in a situation where my "noisemaker" was an issue. I took a mooring in Hope Town in the Abacos, and the balls were pretty close. My gen exh is on the port side water line, and there was a couple on a sailing cat right next to me. Those balls are CLOSE. Without being asked, I moved to another ball where my port side was exposed to no one close. Later I joined the couple for a beer and they asked why I moved. Told them I would need to run the gennie later for a few hours to top up batts, and worried it would bother them. They thanked me repeatedly!!

That's the first and only time it was an issue in several years of cruising. Usually I try to keep away from others for all sorts of reasons.

Roughing it is an opinion , we have no noisemaker , and not even shore power , a single 85W solar , and a propane reefer take care of on board needs dockside or cruising.

AM-FM radio , VHF and autopilot , is about it,for toys.

Not an extravagance , but we do have 2 ranges installed.

A gymboled propane unit with fiddles for southern living and a Dickinson Pacific for winter operation.

The sailboat cruisers have discovered a product to keep their boats cool. It's a rigid hatch cover made by a North Carolina company. I am using one of their covers on my trawler siding doors, and we love them. Helps reduce the solar heat gain, works a lot better than curtains. www.outlandhatchcovers.com . I have no financial interest in this company. I do know the owners and some very nice folks.

I have to laugh at the "Southern heat" part of the title. Official record high, Fort Lauderdale 98 degrees, NYC 102 degrees, Charlotte NC 104 degrees, Houston 106 degrees, Dallas 110 degrees, Atlanta 105 degrees, Chicago 104 degrees.

I would pretty much say the entire Eastern half of the country.

The only part of the US I would consider boating in the summer without air would be the PNW. Record high, Seattle 96, Juneau 90. While every day isn't a record day, these records do indicate the heat many areas experience. And my luck has been bad it seems for I can't tell you how many times in my life I've been somewhere that the weather was extreme and the locals always told me these are record highs, record lows, record snowfall, record rain, record drought. "We never get weather like this." My response, "Well you have it now."
