Anodes protect your boat hull from corrosion where salt water attacks metal and causes it to deteriorate, and therefore needs to be replaced periodically. An aluminium anode is suitable for all water types whilst zinc anodes are suited to salt water. A sacrificial anode will always be the least noble and will not attract any of the electrical current, therefore ensuring that your boat is fully protected. Check out our wide range of anodes from leading brands such as MG Duff, Plastimo and more. If you are planning on heading out on the water soon then make sure that you are fully prepared and take a look at our boat maintenance section.
