Protect Your Boat’s Hull with Zinc Plates
Fisheries Supply is a leading supplier of high-quality zinc plates, also known as hull anodes or hull zincs, designed to safeguard your boat's hull from galvanic corrosion. These anode plates are essential for boats with bonded electrical systems, as they act as sacrificial components that corrode before the aluminum and stainless steel parts of your boat.
Why Zinc Plates are Essential
Zinc plates, also called hull anodes or hull zincs, play a crucial role in galvanic corrosion protection. When a boat is immersed in saltwater, dissimilar metals create an electrical circuit. Because zinc is less stable than stainless steel or aluminum, it corrodes first—sacrificing itself to safeguard more valuable components.
Key Takeaways
- Zinc plates are sacrificial anodes essential for galvanic corrosion protection.
- Available in multiple forms—slotted, bolt-on, and freshwater magnesium solutions.
- Regular inspection ensures ongoing hull and equipment protection.
- Nationwide shipping and expert support are available from Fisheries Supply.
Types of Hull Anodes Available
- Commercial slotted zinc plates – customizable mounting options
- Pre-drilled rectangular, oval, or custom-shaped transom anodes

- Magnesium anodes engineered for freshwater environments
Our knowledgeable representatives can guide you in selecting the correct hull anode based on your boat, water type, and installation needs.
Key Considerations When Choosing Zinc Hull Plates
- Metal stability – Zinc corrodes before more valuable metals, offering critical protection.
- Surface area – Protection levels vary based on surface area, water chemistry, and boat size.
- Monitoring – Inspect zinc plates frequently and replace when significant wear is visible.
