Brian H.,
my idea is to paste the peltiers direct to the hull wall below the water line,
as the heat differential you can get between the 2 sides of the peltier
Improves efficiency. I intend to put a skin of fibreglass over them maybe
raised 1/2" above the peltiers & blow air through. The peltiers are only
1/4 as efficient as a conventional air conditioner but take up a lot less space
& only have the fan noise. 
The great thing about peltiers is you just reverse current & have a heater
Just as efficient as a bar heater.

I couldn't get the Kydex to vacuum around my mold before it cooled to much to still be flexible. I tried hitting it with a heat gun while it was under vacuum, but that just melted it.  Not yet discouraged!

Haven't tried it yet, just got my activated charcoal and micro sieve material for the filter, but I want to use a peltier water cooling module to chill the water going into the compressor's cooling jacket. The 6 chip one, with the water heat exchangers on the sides and cooling fins in the middle, has a design problem. The supplied fan can't pull enough air to really pull off the heat. Ordered a few sizes of radial fans to see if they work better.
