You displace enough of the oxygen and drop the level down to less than 11%, you gonna die.

I think the dry ice could work. Put dry ice pellets in a cooler the has a coiled tube in which you would pump air through. The tube would not be open to the "dry ice air" at any point of its journey. You would have to keep the cooler sealed for leaks except for a vent since you don't want a co2 bomb.

Think I'll make one the weekend...

The majority of deaths when people are trapped in an avalanche are not caused by the weight of the snow, but by asphyxiation (b/c u breathe in O2 and breathe out CO2). Depending on the size of the space ur in, there will be more CO2 than O2........and then u get really sleepy!

I looked into those units also, but we went with the red-neck air option. $89 window unit from home depot, home made shroud to fit the hatch opening. Kept the cabin at 68* in the Key West sun.

Of course you need shore power or a genny to run either of these units.

Yes its pretty much the same scenario as a swamp cooler for lack of a more definitive explanation!!!!

West marine has them now but I looked on Criags list and found one for $200.

They work great for a go fast cuddy, you do need a AC source. Like the reviews say it's loud but on our old dock that was a good thing,,,,,,,,,,,,,,,,,

In order to dehumidify the air within the cabin, you will need water temp to be around 45-50 degrees. You need this cold of water in order for the coil to reach dewpoint of the air going across it.

If the water temp is above that (which most likely it will be), you will only lower the ambient temperature (sensible) and will not remove moisture (latent).

The nifty marine AC unit was the suitcase one that actually was an air conditioner that you had two hoses connected to it. It was basically a water cooled AC unit that used raw water to cool the condensor and then dumped the warm water back into the lake. 120 volt and the size of a suitcase.

I agree with the others about the ice cooler. You would need 2200 pounds of ice to accomplish 12,000 btuh of cooling.

We had to turn our stereos up to drown out your loud azz hatch A/C.


The 1st sign of those ice coolers not working......cheap price.

Look for a used permament mount A/C unit around 6000BTU (to avoid storage issues) and a Honda 1000 gen. and you are good to go, plus you have the abilty to run other AC items.
