Thanks in advance!
It depends on what you mean by cool.
The die hards will tell you to anchor
out so the boat
will swing to the breeze (if there is any) and so provide a cooling
flow through hatches and after market wind
scoops. Some multi hulls open their escape hatches
to catch breeze off the water
Others will tie up to a dock
and run the boats air conditioning
coolers off shore power
.. One cheap
but ugly solution is to use cheap
air cooled household domestic units jammed into a window.
Those with lots of money
will buy enough lithium batteries
or muffled water cooled generator
or other charging
sources to provide enough grunt to run the on board marine
air conditioners all night without need of a generator
if the battery
bank is up to it.
Then again others will make do with a 2KV noisy air cooled generator to power their air con on minimal settings.
The problems the die hard and the minimalists have is that if you are anchoring
in summer near midges, sand flies no-see-ums, biting flies and gnats is that you will need insect screens which really degrade breeze flows. Those with under powered solutions "make do" but can usually only do one cabin
and not all night and so still sweat it out, better than nothing, just an irritant for neighboring boats.
From our own anecdotes of the matter we had an Onan generator that would run aircon, water maker, clothes washer, charge batteries
and heat water and also dehumidify the boat
to reduce mold
- without ever needing to touch a dock
except for fuel
or rely solely on additional high power solar
arrays. The costs is the capital investment,fuel and maintenance
. An alternative is to run a propulsion engine
with a large alternator
, but that is not a good long term solution for that engines life.
IF the solar route
, the high costs is Lifpo batteries and electronics
, and really high costs if installed by professional marine
electricians to do it properly and safely as opposed the the DIY
One downside to solar of course is that a week of overcast weather
with zero wind
and hot sticky humid tropical bug filled nights only needs to occur a few times for it to make you think again. Carry a lot of deet.
So basically it comes down to location and weather/insects and budget
