2 Solar vents, will do wonders in cooling the cabin down.

I agree.. but they don't do much for you at night, when you really need the extra cooling, when you're trying to sleep.

BTW, I have two solar vents on my boat... and they help keep it much cooler when she's at the slip all closed up and waiting for me to arrive.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

I don't think so, not unless you confine yourself to a single stateroom or a very small cabin

Maybe ice melt rate would be a more effective measurement with the KoolerAire unit....... :-)

It would be a bit of work, but why not take advantage of the very water you are floating on? I've often thought of rigging up a form of rad / pump / fan system that will pump cool water through a rad from under the boat, and pass a fan through the rad - wouldn't this provide adaquate cooling? I'm sure there are boxed systems like this no? The power requirements would be very low (a small pump and fan combo), and you might even have enough of a temperature differential between the ambient cabin temperature versus the water temperature to condense moisture from the air?

The bigger, better, and of course more expensive solar/battery 24hr vents will run all night. I've been using them on all my boats for the last 15 years.

Stan-

I've got two of the Nicro 24-hour solar vents on my boat... while they do move a bit of air at night... a Hella Turbo or Caframo Bora moves a lot more air, and is directed where the cooling (ie my carcass) is most needed, rather than the cabin in general.

Just wanted to make sure he was aware of the different flavors of solar as there are still many 'solar only' daytime vents being sold. We also have always had a Hella 12v fan directed across the berth for cooling air movement and the 'white noise' we have become accustomed to needing. I have also set up a kind of 2 stage cooling system on our boats - the 'assisted passive' 24hr solar intake and exhaust, but when it gets Really Hot I would kick in the 12v Hellas strategically placed to move the air in and out faster in those same directions.

Passionkid-
That's classic "chilled water" cooling/refrigeration. The problems on a boat are that first, you need power to pump the water all the time. Second, raw water is going to have all sorts of crud in it, which means filtering it, and attending to cleaning out the system from time to time. And then the usual problems with water pipes, leaks, electrolysis, clogging < g > but it certainly can be done.
