Camp Zinc Anodes/Zincs
Camp Zinc Sacrificial Anodes: American-Made Corrosion Protection
When it comes to defending your vessel against the relentless threat of galvanic corrosion, few names carry more weight than Camp Zinc (Camp Company). Marine anodes and zincs are the unsung heroes of any boat's maintenance routine — small, replaceable components that sacrifice themselves so that your propeller shafts, rudders, hull plates, and drive components don't have to.
Camp Company is one of the leading American manufacturers of marine sacrificial anodes. Their zinc and aluminum anodes are produced domestically and formulated to comply with US Military Specifications (MIL-SPEC), ensuring consistent alloy composition and reliable electrochemical performance in salt, brackish, and fresh water environments.
A Comprehensive Lineup for Every Application
What sets Camp Zinc apart in the anodes and zincs category is the sheer breadth of their product range. Whether you're protecting a weekend runabout or a commercial working vessel, Camp has a purpose-built anode for the job. Their lineup covers:
- Hull Plate Anodes – Oval and rectangular hull plates (such as the A-24, A-25, A-90, and Pacemaker-style B-12) designed to mount flush on hulls and provide broad cathodic protection to the entire underwater body.
- Shaft Anodes – Barrel collar and donut collar zincs in both standard and metric sizes, engineered to clamp securely around propeller shafts of varying diameters.
- Rudder Zincs – A full series (R-1 through R-7) purpose-shaped to mount on rudders and protect these critical steering surfaces from pitting and galvanic attack.
- Engine Pencil Anodes – Compact threaded zincs (E-series with NPT brass plug fittings) sized to fit the cooling passages of most inboard and sterndrive engines, protecting internal metal components from corrosion.
- Outboard & Sterndrive Anodes – Direct-fit trim tab and bar zincs for Mercury, Mariner, Yamaha, Honda, Suzuki, Evinrude/Johnson, and Volvo Penta outboards and sterndrives.
- Line Cutter & Specialty Zincs – Including spur zincs for line cutters, bow thruster zincs (compatible with Vetus thrusters), and the Grouper Zinc, which ships ready to deploy with galvanized wire rope and an electrical connector.
- Keel Cooler Anodes – Specialized shapes like the X-45-3 Walter Keel Cooler zinc, designed to protect tube-style keel coolers on inboard engines.
MIL-SPEC Alloys, Made in the USA
Every Camp Zinc anode is manufactured using the latest US MIL-SPEC alloys, a standard that governs the precise chemical composition of the zinc material to guarantee optimal sacrificial activity. Anodes made to lesser alloy standards can passivate — forming a surface layer that inhibits corrosion and leaves your boat's metal components unprotected. Camp's adherence to military-grade specifications means their zincs remain electrochemically active throughout their service life.
Camp anodes are engineered for use on recreational, commercial, and military vessels alike, reflecting a level of quality that goes well beyond the average boater's weekend needs. With over 28 products available in this category, the Camp Zinc lineup offers one of the most complete selections of sacrificial anodes for sailors, powerboaters, and commercial mariners.
How to Choose the Right Camp Zinc Anode
Selecting the correct anode comes down to three factors: the type of water (salt, fresh, or brackish), the specific component being protected, and the correct sizing for a secure fit. Zinc anodes are the traditional choice for saltwater applications, where their strongly negative electrochemical potential provides maximum protection against galvanic attack. Camp's broad size range — from pencil-thin engine anodes to multi-pound hull plates — ensures there's a properly-sized anode for every position on the boat. As a general rule, anodes should be inspected regularly and replaced once approximately half of the material has corroded away.
