Martyr CMDIVERZ – Zinc Diver's Dream Hull Anode
Part Number: CMDIVERZ | SKU: 194-CMDIVERZ
The Martyr CMDIVERZ is the full-size zinc Diver's Dream hull anode, designed for saltwater and ocean-going vessels. Its flat-plate, low-profile design sits flush against the hull — minimizing drag and making it easy to inspect or replace during routine bottom work. Zinc is the standard material choice for saltwater environments, offering reliable galvanic protection for steel, aluminum, and fiberglass hulls.
Specifications
- Dimensions: 12" (L) × 6" (W) × ½" (H)
- Material: Zinc alloy — recommended for saltwater and ocean environments
- Mounting: Two-bolt flat-plate design; hardware not included
- System: Hull cathodic (corrosion) protection
Compatible Applications
- Saltwater powerboats and sportfishers
- Ocean-going sailboats and cruisers
- Steel and aluminum commercial hulls in saltwater
- Any vessel requiring a full-size flat-plate hull anode in salt or ocean water
Note: Zinc anodes are not recommended for freshwater use — they passivate and lose effectiveness in low-conductivity water. For freshwater hulls, see the Magnesium CMDIVERMINI. For mixed fresh/salt use, consider the Aluminum CMT-DIVERA.

Parts Desk Insights
Best use case: The CMDIVERZ is the go-to full-size hull anode for saltwater boats. It covers a larger hull surface area than the mini version and is the correct choice for vessels over 25 feet or those with higher metal mass in the water (twin engines, large props, metal rudders).
Common customer questions: Customers sometimes ask whether one large anode is better than two smaller ones — for most production boats, one CMDIVERZ placed amidships provides adequate coverage, but twin-engine or metal-hull vessels may benefit from two. If a customer's existing anode is depleting faster than one season, it's usually a sign of a stray current issue rather than an undersized anode.
