Re: How do you do it... (no AC)

In my 3 years in La Paz I have not got used to heat. AC was the ticket

As for a boat... I would try mist evaporative cooling. Install a mister on a good fan so it will direct water (mist) flow directly at the blades, and fan will blow a cooler air which may help. There are some cheap mist cooling systems on ebay. I am definitely going to install it on my boat (to cool a cockpit).

It is all the panoramic living room windows on catamarans that let heat inside - little to do with deck thickness at all. Of course, those windows also let light inside and allows one to see all around while eating dinner, etc.

Macgregor 26... seriously. Phone app won't allow photos but I can email them to you if you like. Insurance job right now on one that crunched the hull deck joint. Chopper gunned to boot, and no access holes can be cut in liner there without problems.

Re: How do you do it... (no AC)

Our solution is pretty simple. If it's too hot, we sail to somewhere cooler. If it's too cold we sail somewhere warmer.

Wrap in a wet cloth and sit in a place where there is some draft. This cools down quite a lot. Light cotton cloth like a huge indian scarf or something works best.

Misters work great when it isn't humid. In Palm Springs, for instance, they use misters around restaurant patios to keep them comfortable. Buttonwillow Raceway uses them too under their HUGE canopy. They're like sprinkler heads. Spaced about 4-6 feet apart. If you're in a marina you could probably just plumb a hose to a piece of PVC under the bimini or whatever you have with a couple of misters and it would keep the cockpit pretty nice in the shade.

I don't believe Greenland is ever "nice". That is why they named it "green" to get people to go there.

Now Iceland ..................

Re: How do you do it... (no AC)

someone earlier mentioned diet.

i wont get too deep into the specifics but foods that grow in hot temps will always dissipate body heat (same works in advance).

sure bets are citrus and spicy foods.

i dont mean to suggest you will be reaching for a sweater after drinking a glass of orange juice but eating carrots and potatoes and drinking dairy is going to work against your attempt to stay cool.

Re: How do you do it... (no AC)

It's your Russian jeans. Change into shorts.

No really, I have trouble with the heat and sweating also. My wife doesn't even "glow" and I am soaked.

Weight has something to do with it. - I have a gut but am skinny everywhere else.

Diet has something to do with it too. - Coffee will make me sweat more easily. Beer for sure. Most any alcohol will do it.

I kept a spray bottle at the wheel. Used a lot of it.

What I found is there is a lot to the diet and alcohol thing. If outside I wet my shorts - with water of course. I have also found that the longer you are "out in it" the more you adapt. At home I try not to go back in the house till I am done outside. Each little trip back into the air conditioned house means I have to acclimate all over again. I am used to 82 in FL - not too bad. But I know how you feel by your description. In FL now it is 89 to 94 and humid. Only 3 or 4 more months of it.

I hope my next boat will have AC for those windless marina days.

Re: How do you do it... (no AC)

It is 102F in central Texas, but the humidity is very low. Stop complaining and eat your dinner; Angus ribeye, baked potato, Cesar salad, ice cold lemonade and triple chocolate somethin'... sheesh!

Re: How do you do it... (no AC)

Take a cue from the mexicans, and eat spicy food, it makes you sweat without doing anything. And take a nap during the afternoon when its hottest.
I'd suggestion you create an enclosed sleeping area that you can insulate really well,
then you can A/C just that small space and sleep there comfortably.

Humidity really sucks, living in Florida was unbearable without A/C during the summer.
