When we comissioned our boat
the Admiral threw a fit at the Air Conditioning
option. After 5.5 years of living aboard
she has changed her mind.
We have three Marine
Air units, one in each cabin
. While living aboard
in San Francisco
the units were mostly used for heating
, except when we sailed up to the Sacramento Delta
Now that we are in Central America
we use the units frequently. During the day when we are off the boat, we have to lock it up tight for security
. So when we return we usually run the units 1-2 hours to cool the boat down and de-humidify it. While running, the units usually draw about 3-5 gallons of water
out of the air during that time frame.
We have also used the Air Conditioners underway several times when the interior
of the boat was so hot we couldn't sleep during night crossing along the coast of Nicaragua
and Costa Rica
To give you an idea of power
Forward Unit is 8,000 BTU and draws about 1.0 kw
The Mid Unit is 12,000 BTU and draws about 1.4 kw
The Aft Unit is 6,000 BTU and draws about 0.8 kw
The mid and forward unit share one water
pump">raw water pump and the aft unit has its own.
Yes Air Conditioning it is a luxuary, but we are happy with the units and would do it again.
If you are in the tropics and can afford it... I would strongly recommend a built in marine
units over window units so you can use them under way and during rainny seasons.
