Does anyone have experience (or heard any evaluations) with this cabin cooling device? It uses sea water and operates on 12 volt with minimal battery drain. Specs say it will provide 3800 to 5000 btu of cooling depending on the water temperature at your location.

Don't really believe it could work!
Mark: I really do not believe that this could really work but who knows. Why don't you buy one and give us a full blown report. I would think that it is only going to be slightly better than a fan blowing directly on you. Out here in the West we have these contraptions known as "swamp coolers". Most people in the east would not know about these but they work on the principal of evaporative cooling. They keep our office about 20-25 degrees cooler than the outside temp. (Now you'd love than wouldn't you?)

btu's
Mark, the real question is if the btu are ample for your size boat. I would not think a 3800 to 5000 btu unit would cool anything but a small cabin and they if the water is cold enough. I don't have any first hand expierence with one of they but they seam undersized and probely not worth the money, don't know for sure but most likely only for use at the dock on 110 power otherwise they would be a major power draw! Cool Luck! Let us know if you get one and what your results are!

Cool Currents
The Cool Currents device runs off DC power, they claim less than 2 amps. It is not a swamp cooler. It takes cool or cold water from around 20 feet deep and pumps it through a radiator type divice and then over the side. It probably won't freeze you out but it could take the edge off a hot day. It does seem alittle pricey though.

It Wouldn't Work Down Here
Or water temperature for a good part of the summer is around 85 and even goes to 90 for periods of time. To go down 20' would be real tough in most places. The biggest part of what the AC does for us here is to remove the humidity and I do not think that the contraption is going to help with that. I could be wrong and if the folks making the thing are out there and want to send me one I'd be happy to try it out.

Build your own?
That is definately a product that would work, if the water temperature is cool enough, but it is extremely pricey for what they are delivering. Since you are far, far away from Biloxi, ignore what Rick had to say. Your home and office air conditioners work on the same principle this thing does - blow air through a radiator or cooling coils, and the air cools down. But hoses, a good pump, a fan, and a radiator unit are cheap. Look for something just like the cooling radiator on the back or bottom of your refrigerator but with larger diameter coils. I think I just found a project for the weekend. IANAL, but my understanding of patent law is that if you make one unit for personal use you aren't breaking the law.

Brian, I beg to differ.
There is one Big difference between this type of unit and the air conditioners in your home and office -- A Compressor with liquid Freon (or that new stuff)! And it is this compressor that uses alot of power (that's why we need to be plugged into 115VAC at the dock or have a gen-set on board. Yes they both blow air through a radiator or cooling coils, and the air cools down. But the cooling coils at your home and car can be brought down to "frigid" levels with the compressor and freon......where as this unit will only bring the coils down to (at best) the temp of the water 20 feet down. This solution might "feel" best working where there is a big differential between outside temps and the water 20' feet down. Personally I think a fan with a spray bottle will give you the same "cooling relief" as this unit.

Depends on where you are, Tom
I am not familiar with the waters of Chesapeake Bay; what you said may be true for water in that part of the country. I sail in the Puget Sound and Straits of Juan de Fuca

About to test
The device arrived today and I'm looking forward to testing it over the next few weekends. It worked fine in my kitchen but now I'm in search of warm weather and cool Chesapeake Bay water. Stay tuned for results.
