Exactly. You could of course construct a ship with a closed inner cooling cycle that then dumps the heat to the outside ocean through cooling fins or the like. But that would require developing new technology and building new ships. That would take time and cost money. We can’t possibly do that because line must go up now!
Not new technology, this is how the water heater on my boat works. Closed loop cycle that dumps engine heat into the hot water tank. There’s also a secondary inline heater I can turn on for when I’m entirely on sails.
Would the water need to be desalinated if it’s only going to be cooling the equipment?
If you want the cooling system to survive, yes.
Ocean water is atrociously corrosive, prone to clogging tubes and short circuits much more easily than distilled water.
That’s a mighty big “if”.
