What is the water temperature? It might be possible to simply use a
heat exchanger to dump heat into the water. In thory, it would even be
possible to get the coolant to circulate without a pump.


When it's 112 in the shade?
Water temp was about 87.

Maybe at the surface, or in really shallow water. You've got a huge
heatsink to work with, and as long as the water from down deep is cooler
than the dewpoint, it should also remove humidity. Not sure how you
could do it under way, but lowering a hose over the side long enough to
get to cooler water would work when you are tied up.
