As others said....if you are in a Marina in the Tropics with Temps above 33°C you need AirCon!
, with no wind
and lots of bugs...you want AirCon!
For a No Gen and Drydock
solution... I came up with a "cake and eat it" idea that works great on Stargazer.
I installed a 0.5 HP dripless Window Aircon in my aft cabin
to cool the Owners area and even the engine
room when the door is open
After Start it draws only 1-2 amp 220v and runs easily on invertor.
After testing, I installed permanently with compressor
section in lazarette, insulated well so that only return air circulates and kept escape hatch
below for emergencies.
The hot air escapes out the large deck hatch
