Best Marine Coolers Guide

To not make a mistake, we recommend you to consider a few important factors. They are as follows:


The size is one of the most important factors that matter when buying a marine cooler. Every person needs a product like this for a different reason. Depending on the reason, the user will also choose the right size for his needs. Plus, note that not all boats are equal. So, this means that the size of the marine cooler you choose depends on the size of the boat.

Take a look at the measurements and see if the item you like fits where you want to put it. If the boat is big, then this is not an issue. Yet, it is essential to decide on the size of the unit.


A unit like this will go through several circumstances that require it to last. Most of the marine coolers available on the market are being built to last. Some models come with a lifetime warranty. The idea is the more durable the unit is, the longer the user will be able to enjoy.

Ice retention

In general, manufacturers let you know how long the marine cooler is going to keep the ice intact. Most users are being tempted to buy the model that has the most extended ice retention. The truth is that there is no point in buying a product that keeps then ice for 10 days if your trips only last 2 days. Note that the longer the ice retention, the higher the price.

Non-slip options

Some marine coolers can be mounted, whereas others come with non-slip feet. A feature like this is super important. Otherwise, the cooler will move every time the boat is rocking. The non-slip feet are a bit easier to handle because mounting requires a mounting kit. This kit is usually being sold separately. Yet, the mounted unit will be a lot better secured in place.

Extra features

When looking for extra features, it is a must to look for something that will actually be useful. For example, we recommend those models that allow the placement of a cushion on the lid. On a small boat, this feature comes in handy because there is some extra space where people can sit. Moreover, some models come with a measurement market on the lid. This is super useful as it lets you measure your catch.

Are marine coolers better?

We are not saying that regular coolers are bad, but marine coolers definitely offer a lot more advantages. So, depending on how you are going to use a marine cooler, you can choose one type or another. This is a matter of personal choice.

Are expensive coolers worth it?

These units have a better insulation quality. Plus, the walls are thicker, which means that the ice will be preserved about two times longer than most low-cost coolers. Yet, it is essential that the user pre-chills the cooler with ice a day before he needs the cooler. Note that investing in a high-quality cooler will allows you to benefit from some great advantages. Plus, it won’t be necessary to replace the unit too soon.

How do ice coolers work?

In most cases, the insulation is made of plastic or foam. This insulation lines the cooler’s inside, slowing down the circulation of warm air. The ice maintains the cooler’s inside nice and chilly. The insulation has the role to slow down the warm air through a process that is being called convection. Ice coolers are very appreciated today and popular in every corner of the world.

Do coolers work without ice?

There are many coolers that are being rated for a minimum of two days. The most high-quality ones are being rated for seven days. If the cooler is packed tightly and there is enough frozen food, then ice or ice packs might not be necessary at all. The frozen food will be enough if it is already in block form. Yet, it is recommended to invest in a premium cooler, so that the results can be excellent.
