Trim Tab Anodes & Rudder Trim Tabs

Protect Your Boat from Galvanic Corrosion with Trim Tab and Rudder Anodes

Galvanic corrosion can wreak havoc on your boat's underwater metal components, including trim tabs and rudders. To safeguard these crucial parts, it's essential to install high-quality anodes, also known as zincs or sacrificial anodes. Fisheries Supply, a premier marine supplier, offers a comprehensive range of trim tab zincs, rudder anodes, and replacement anodes to protect your yacht from galvanic corrosion.

What are Trim Tab and Rudder Anodes?

Trim tab anodes, or trim tab zincs, are sacrificial anodes designed specifically for trim tabs. These trim tab zinc anodes are typically made of zinc or aluminum for saltwater applications or magnesium for freshwater environments. They are attached to the top side of the trim tabs to prevent galvanic corrosion.

Similarly, rudder anodes, also known as rudder zincs or rudder/trim tab anodes, are sacrificial anodes designed to protect the rudder from corrosion. Due to their shape, these anodes are often referred to as "button anodes" and are available in zinc, aluminum, and magnesium variants.

Why are Trim Tab and Rudder Anodes Important?

Anodes play a crucial role in preventing galvanic corrosion, a process that occurs when dissimilar metals are immersed in an electrolyte solution, such as saltwater. Without proper protection, the less noble metal (anode) will corrode, sacrificing itself to protect the more noble metal (cathode).

By installing anodes on trim tabs and rudders, you create a sacrificial component that will corrode instead of the more expensive parts of your boat. This helps extend the lifespan of your trim tabs/rudders and other underwater metal components.
