Martyr CMN1Z Zinc Hull Plate Anode

A solid zinc hull plate anode designed for bolt-on installation directly to the hull, keel, or underwater running gear. The CMN1Z delivers reliable sacrificial protection against galvanic corrosion in saltwater environments, with a profile sized to provide meaningful protection mass on mid-size vessels between haulouts.

Compatible Applications

Steel, aluminum, and fiberglass hulls in saltwater
Keel, hull plate, and flat underwater surface mounting
Mid-size inboard and inboard/outboard vessels
Any application requiring a 3.16" × 8.5" bolt-on zinc plate anode
Suitable where standard teardrop or diver-style anodes are undersized for the vessel’s protection requirements

Specifications

Part Number: CMN1Z
SKU: 194-CMN1Z
Material: Military-grade zinc alloy (sacrificial)
Dimensions: 3.16" × 8.5" (approx. 80mm × 216mm)
Mounting: Bolt-on; hole dimension refers to the center-to-center distance between mounting holes
Best For: Saltwater
Weight: ~1.18 kg

Mounting Notes

The hole dimension listed refers to the center-to-center distance between mounting holes, not the overall anode length. Verify your hull’s existing bolt pattern against this measurement before ordering. Mount to a clean, bare metal or bonded surface for best electrical contact. Use stainless steel fasteners and ensure solid metal-to-metal contact with the hull or bonding system.

Parts Desk Insights

The CMN1Z is a purpose-sized hull plate anode for vessels that need more sacrificial mass than a teardrop or diver-style anode provides, but don’t require the full coverage of a large-format plate. The most common ordering mistake with hull plate anodes is selecting by overall dimensions without confirming the bolt hole spacing — always verify the center-to-center hole measurement matches your hull’s existing pattern before ordering.

For vessels operating in brackish or mixed-salinity water, an aluminum hull anode is a better choice than zinc — zinc can passivate in lower-salinity conditions and lose effectiveness. See the CMDIVERA aluminum hull anode for a brackish-water alternative.
