One of the differences between an Boat Air Conditioner and an
Evaporative Cooler are the methods used to produce cool air. An
Evaporative Cooler has cool air that feels like an ocean breeze.
A Boat Air Conditioner has dry cool air like you feel in an aircraft
cabin. People in dry climates generally prefer the feel of an
Evaporative Cooler and those in humid areas generally choose a
Boat Air Conditioner.
A Portable Boat Air Conditioner or Evaporative Cooler are preferred
if installing an after market Boat Air Conditioner is not economically
feasible. Also if repairing a factory installed Auto Air Conditioner
is not possible, then consideration should be made towards an
Alternative. A Portable Cooler can be moved from a boat to a vehicle
and will provide relief while providing less strain on the engine
and, of course, money. The 12-Volt MightyKool Models are the hands
down the most popular cooler with boaters because of the low energy
they consume from your batteries.
1. Will a portable system cool my boat cabin?
Seems like a logical question, however Portable Cooling
Systems are typically designed for Spot Cooling, not area cooling,
even though they may cool the cabin at some point.


One gallon (3.75 liters) of water will last around two to
three hours in the daytime and four to five hours during the night
when used for evaporative cooling in dry desert climates. The
"Ice Water" models are capable of using from 10 pounds
(4.5 kilograms) up to 20 pounds (9.0 kilograms) of ice per hour,
or more, depending on the ambient temperature and day or night
operation.
A 105 Deep Cycle battery, "not being charged", allow
the MW1, MW2 to operate for 50 to 80 hours and the "Ice Water"
models like the MK3, MK4, MAC & M400 will operate for 25 to
35 hours before the battery needs charging. The Swampy Models
will operate about 8 hours before the battery would need charging
as they draw more energy.
