Martyr Anodes Small Streamlined Hull Anode

The Martyr Anodes Small Streamlined Hull Anode is a bolt-on sacrificial hull anode (also called a hull zinc or plate anode). It gives cathodic protection to the underwater metal parts of boats and marine vessels. The anode corrodes in place of more valuable submerged hardware, which helps prevent galvanic corrosion. Its compact, low-profile streamlined shape helps limit drag and turbulence.

Key Features:

• Streamlined, low-profile design for hydrodynamic efficiency
• Made from premium marine-grade alloy that meets military specification standards, so it wears predictably
• Pre-drilled mounting holes for bolt-on installation on the hull
• Helps protect submerged metals such as propellers, shafts, rudders, and other underwater hardware
• Available in different anode alloys for saltwater, brackish water, or freshwater use

Inspect sacrificial anodes regularly. Replace them when they are about 70% eroded so your vessel's underwater metals stay protected. Martyr is a trusted name in marine anodes, and this hull anode is a dependable choice for routine corrosion-protection maintenance.
