How To Keep Your Electronics Safe at Sea

Using electronics while at sea isn’t a new phenomenon at all. Boaters use a wide variety of electronics ranging from laptops to sonar equipment. Let us look at the various scenarios that can happen when you are on a boat in the middle of the sea.


Here, the electronics can become fully covered with water from a few minutes to hours. When this happens, most of the electronic parts of the equipment get destroyed. This would mean you replace the parts that have been short by electricity. This renders the equipment useless, and replacement can be expensive.

The water, if left for long can lead to corrosion of the internal parts of the equipment, leading to poor performance or total failure of the equipment.

Water conducts electricity, therefore, it can lead to changes in circuit behaviour. If you power on the device before the condensation evaporates, you experience short circuits between the components which can cause device failure.

Direct Hit

This occurs when water gets poured on the electronic momentarily, for instance during rain. Many times the equipment can be rescued and reused since a lot of water may not have got to the components. The equipment might look worse on the outside as compared to the inside.

The solution here would be cleaning off the water and drying the equipment. A direct hit rarely causes corrosion.

High Humidity

This occurs when you have electronics sitting in a room that has water. The electronics are usually off the floor on a desk, shelf or a table. The equipment doesn’t come in contact with the water, but the high humidity can affect the electronics.

The electronics that are exposed to high humidity can easily get spoilt and need to be cleaned to continue working.

You will be surprised to find that in such a scenario the humidity is not the major culprit – dust is. Dust encases the circuit boards, which don’t “breathe” properly causing overheating. Well, you can blow out the dust and get your circuit boards working properly.

When humidity collects on the dust, it cakes into a mud-like substance that clings onto the board. This means the board can easily overheat, leading to poor performance.

Low Humidity

Low humidity areas can cause static electricity discharge that can lead to irreversible damage to electrical components.

Tips to Weatherproof Electronic Equipment

A basic method that most users employ is to cover the equipment using plastic bags that are meant for this purpose. Others use normal plastic bags from grocery stores, which is not such a good idea because they can be easily punctured.

Some users go to the extent of wrapping electrical tape around the delicate areas to protect them, but this can only work for a limited amount of time.

Some brands boast of making sprays that can waterproof electronics. However, such sprays can leave a coat of residue on your electronics, something that you don’t want to happen. You also need to redo the spray after a certain time.

One of the best ways to protect the electronics is to use the bags that are designed for the purpose. A big advantage of such bags is that they are made of durable, weatherproof material to keep your equipment safe.

Laptops are vulnerable to moisture and humidity; you can use to protect them using waterproof bags from

In Closing

You need to be able to communicate and work even when you are on your boat. To achieve this, you need to protect the electronic equipment from water and humidity. Failure to do this leads to corrosion and failure of the equipment.
