A No-Frills Guide to Buying a Portable Boat Air Conditioner

Best Portable Boat Air Conditioner

Buying a boat was definitely one of your smartest decisions. But those hot, summer days spent cruising with the family made you realize that you still need one more thing for your precious investment—air conditioning.

Your boat’s ventilation and air conditioning system keeps you cool during dry, humid weather to extend your cruising season. Having a fully functional air conditioning unit also enhances the value of your boat, making it easy to sell in the future.

You’ll find several air conditioning options for your boat. Self-contained air conditioning units are mostly used by small and medium-sized boats as well as split air conditioning systems. Chilled water air conditioning is also another great option, especially for yachts and larger boats.

But if you’re working on a budget or you’re not using your boat as often and would want to cool only a small part of your cabin, a portable air conditioner is your best option because it is lightweight enough to be placed anywhere on the boat and gets the job done without breaking the bank.

Now that you know exactly what you should be looking for, we rounded up three of the top portable air conditioners that you can invest on for your boat:

The things to consider before buying a portable air conditioner

Buying a portable air conditioner for your boat is a lot different from doing it for your home. So, make sure that you consider these things before you go shopping:

Think about where you’ll place the air conditioner. Pick a spot on the boat where you spend the most time in and place the air conditioner where the cool air blows directly into that area.

It’s also important to consider the stability of the air conditioner once it’s in that spot so you’re sure it doesn’t tip over when you’re on the water.

Think about where you’ll place the vent hose. Find a vertical window or hatch to run the vent hose outside. Most portable air conditioners come with a 1.5-meter hose, so think about the best spot on your boat where you can fit a hose adaptor to guide the hose outside the boat. Remember that the vent hose will easily get hot, so make sure that you’re not running it on a flammable surface.

The most important design features of a portable air conditioner

When narrowing down your options for a portable air conditioner, try to look for these crucial design features:

Auto shut off. Most portable air conditioners will come with a reservoir or pan where the condensate goes to avoid pooling into the AC itself. To know that the pan is almost full, you will be notified by a light on the AC and the unit automatically shuts off.

Hot air exhaust. Since your AC will be placed inside the boat, which could get really hot when you’re on the water, a hot air exhaust is essential to keeping the unit from overheating.

A vent hose kit. Aside from a 1.5-meter hose, you should also be looking for a hose adaptor, pipe connector and venting kit to be included in your AC unit so you won’t have to buy them yourself.

LCDI. Go with a portable air conditioner that has a Leakage Current Detection and Interrupt feature located after the connection socket to ensure safety.

The takeaway

One last tip before you start shopping for your portable air conditioner is to calculate the number of British Thermal Units (BTU) required to cool your space. Measure the square footage of your cabin by multiplying the length by width to get the area.

If you’re cooling a cabin below deck, you’ll need a load factor of 80, 120 for mid-deck and 150 for above deck. Multiply the area of the cabin by the lead factor to determine the BTU needed to cool your cabin.

Finally, make sure to do your research first before finalizing any purchase.

Ask for recommendations from other boat owners who have their own air conditioning units and always keep the crucial design features in mind when you’re narrowing down your options.
