Some DIY A/C.

I got the vibe from the other A/C thread that some boaters only really need A/C in more extreme times, so I came across these solutions that may be able to be adapted to a boat. Thought they might be a little more economically helpful than popping for a unit that won't be used but a relatively short time of the year.

I was thinking about doing the same thing, but instead of having a bucket of cold water/ice, just circulate ocean water through it. Around here, the ocean almost never gets above 65 degrees.

That crossed my mind, but I didn't know how warm the water did or didn't get. Hook the fan and a small aquarium pump up to a solar panel and voila! Maybe.

That's actually how "whole building" air conditioning systems work. They chill water and send it around in pipes to hundreds of heat exchangers located in each office, because compressed gas would have major pressure changes running through systems on that scale.

The only trick to using raw sea water would be keeping it from clogging and rotting the plumbing and pump.

you have a windscoop, you don't need a fan. Just set up the copper tubing in the hatchway and let the wind blow through it. Slip the intake tube overboard (weighted down with a strainer over it, perhaps?) and leave the outflow tube to play over the deck to keep that cool too. Use a solar panel to power the pump and you have an eco-friendly Whole Boat Cooling System!
