As others said....if you are in a Marina in the Tropics with Temps above 33°C you need AirCon!
At
anchor, 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
