Benefits of Using a Refrigerator for your Boat

It provides more flexibility and mobility for your maritime travel. Bringing a soft-sided cooler with you  can become tedious. You can only pack enough food for one day, and it is not enough to entertain other guests.

You must constantly stop to restock, or only bring enough food for a short trip. Soft-sided coolers are difficult to clean, leaving room for unsafe food storage conditions. A boat refrigerator is a more sanitary option.

As the day wears on, the ice in a soft-sided cooler will melt, leaving your food susceptible to dangerous bacteria. The United States Department of Agriculture (USDA) reports there are two different families of bacteria that cause problems with our food.

Pathogenic bacteria grows if food is kept over the safety zone temperature of 40 degrees Fahrenheit. Pathogenic bacteria are odorless and tasteless, but can cause serious gastrointestinal effects.

Spoilage bacteria turns food rotten over time. Refrigeration keeps pathogenic bacteria away and slows the growth of spoilage bacteria, keeping your food safer for longer periods of time. If traveling on a boat at sea, it is important to avoid pathogenic bacteria and to keep food fresh until reaching a point to restock.

We’ve taken a close look at the choices and narrowed them down to our top three favorites. We chose a few different types to give you options that met or exceeded our expectations for best refrigerators for a boat in 2021.

What to Look for When Making a Purchase

How Much Time Do You Spend On Your Boat or RV?

The amount of time you plan to spend on your boat or RV is a factor when deciding the onboard refrigerator capacity you need. If you only take short day trips, a unit with a smaller capacity will serve the purpose of keeping small amounts of food.

You can get away with a unit with little or no freezer capacity. Longer trips for overnight travel or spending weeks at a time at sea will require more food storage space.

A unit with both refrigerator and freezer space would be best in this case for the most food storage options. Take a look at your travel plans paired with any size restrictions of your boat and you should be able to get a clear picture of a good marine fridge freezer for your needs.

What Will You Use for a Power Source?

Another important consideration is the power source for your unit.

What kind of power options are available? Some units come with multiple power adapters, allowing you the flexibility to utilize everything from your car’s power outlets to solar options. 

The more options a unit gives you, the more chances the until will work with your needs.

What’s the difference between a refrigerator, an icebox and an ice maker?
