Just Google 'Mattress cooler USA' They do the evaporative cooler like ours and also a compressor version. The evaporative version is actually 12v so easy to wire from a boats power supply.
Given the heatwaves many are suffering ... mini AC ?

Living in Africa I would not be without air con in the summer especially in the bedroom at night.
We have had both evaporative air coolers and heat pump type air cons at home and i my office with employs
The evaporative type are cheaper but are not really effective in hot climates or where the air humidity is high
We threw away all out evaporative cooler away and replaced wit portable heat pump air cons the only issue on a boat is the removal of the waste heat air and evaporated water.
The waste heat in my system is removed by recurlation water in the skeg of my oat and the evaporated water. is directed into my shower tray and the pumped overboard when showering
Water cooled condenser units I have three for different sections of the boat
Air everapor units wit ducting to be built to duct cooled air to the required location

I was looking into this but have found that a Meacofan 1056 really makes a world of difference. When the temperature in the boat is around 30C it's fine with the fan on the lower settings & on the lower settings it's the quietest fan I've come across. So definitely recommended for when you have 240v available...

But it doesn't have any cooling feature - it just moves air around; it's just a fan. So it may cool you down a bit, but it won't cool the space you're in.

mmmm I was going to check it out ... tks for heads up.
I have a 5 quid 12v fan that is suction cup mount to window on my SR25 .... its over 15yrs old and still works fine ... it has static and swivel function but only one speed.

The selling point is the silent motor...we don’t run our regular fan during the night because of the noise...mind you, you don’t really hear it over the generator

Right now the temperature outside the house is 36C. A little less indoors but quite uncomfortable - until I turn on our ceiling fan. It's quite big, like ones you see in pubs in UK, about a yard in diameter. Transforms our comfort sitting here

I'm not knocking fans - I have ceiling fans at home, and they help. But @Refueler was looking for air conditioning, and a fan isn't air conditioning. It makes you feel cooler, probably by carrying body heat away and aiding cooling by evaporation of sweat, but it doesn't actually make the air or the room any cooler. Further, I suspect it would be less effective in high humidity.

We have a Caframo aboard in Greece and find it helps a lot. Noted for its low electrical consumption.

Awaiting modified Tesla heat pump

After reading the details of the Tesla heat pump and Super Bottle for the model 3 and Y it follows that perhaps only by using a complete ev battery pack along with the heat pump can we have air conditioning.

With a 60 kWh Tesla battery using 10 hp the motor will drive the boat for 10 hrs without air conditioning

Today in Supermarket :
Moderate size proper refridgerant AC unit ... 240v / 800W ... suitable for medium size room ... portable on wheels. Complete with hoses / window exhaust kit ...
Size about 80cms high, 30cms square ...
Not small I agree ... but at 199.99 euros down from its RRP of 349.99 ..... maybe not such a bad idea !

I bought a more powerful one of these... and they don’t work. I don’t know if it’s because a fiberglass box is much harder to cool or not but the effect is negligible for all the the effort (the weight of getting it on and off, the ducting and finding convenient porthole and drainage)

Tks for that ... money will stay in pocket !!
My water evaporative smaller machine DOES work - so maybe I'll just revert to that idea.

The main issue with these is that the exhaust blows hot air out, but the inlet pulls cool air from the boat, creating a vacuum. This causes hot air from outside to replace it. On a boat this would be particularly bad with all the various gaps. They usually do blow very cold air on things though and will dehumidify so definitely can increase comfort despite being a total PITA to use

Have the same. Very impressive little 12v fan and uses 0.4 amps. The fancy oscillating one has bad reviews on Amazon - I bought the basic £50 job and it’s great.

We have 10 fans onboard. Essential in the Tropics. We have them over the bunks (5 fans), two in the saloon, one in the nav station, one in the galley and one over the work bench in the engine room. 6 of them are Hella fans and 4 are 10" truck fans that are supper quiet and move a lot of air.
The best bit of kit though by far for a good nights sleep is the mattress cooler. On a hot night with fans running and mattress cooler, we get a great night's sleep with no need for aircon. Mattress cooler uses 8w

I have the same fans and do work great for warm nights but when the temp realy gets hot you need cooled air as well where we are
