A boat anode is the essential equipment to protect the metal parts of the boat against corrosion. With its ability to limit the effects of corrosion, this accessory can extend the life of a boat. What does it really consist of? What roles does it play? What are the different types? Here is everything you need to know about a boat anode.
The purpose of a boat anode
The metal parts of a boat that are in contact with sea water are subject to corrosive effects. Corrosion is quite natural if the metal is in direct contact with sea water. It can attack important parts of the boat such as the propeller, shaft, rudder and metal hull. In this way, it can affect the proper functioning of your equipment. This is why a boat anode is so important. It is a piece of equipment that will limit the formation of corrosion on metal parts.
This part owes its ability to prevent corrosion to its electropositive metal structure. This will help the metal parts to resist corrosion perfectly.
The different types of boat anodes
A boat anode exists in many types which differ according to the design material. Firstly, there are anodes made of magnesium which are used when sailing in fresh water. You can also find zinc, which is the ideal material when sailing at sea. A boat anode can be made of aluminium which is designed for brackish water.
There are some people who go in for designing their own boat anode. If you want to do this, it is necessary to ensure that the equipment has an aluminium content of 99.996%. The iron content should be minimal. For optimal efficiency, the boat anode must meet the applicable standards.
How do I choose a boat anode?
In order for a boat anode to perform its function properly, it is necessary to choose it well. To do this, you must take into account the type of navigation and the model of boat.
Also, an anode can be differentiated according to the way it is fixed. While some are screwed in, others are bolted in. There are those that are welded and suspended. In addition, there are many different shapes available. From the plate to the carp tail, without forgetting the oval one, the shape is chosen according to your needs.
If you have difficulty in choosing, it is advisable to seek advice from an expert in the field.
Replace the anode at the right time
Over time, a boat anode will wear out. It is therefore necessary to replace it. It is necessary to check its condition from time to time so that it can be replaced in time. In principle, an anode should be replaced every 5 years for inland navigation. It is also recommended to change this part every time the boat is refitted.
