When corrosion shows up on a hull or propeller, it’s usually already too late. I’ve seen many boat owners treat sacrificial anodes as an afterthought—buying replacements based purely on size rather than specification. Reviewing the MgDuff Anodes Catalogue carefully can completely change that mindset. The real value isn’t just in listing products; it’s in understanding material composition, water type compatibility, and installation strategy. Aluminum, zinc, and magnesium all behave differently depending on salinity and electrical conditions. Choosing incorrectly doesn’t just shorten anode life—it can accelerate corrosion on critical components.

The reason the MgDuff Anodes Catalogue matters today is because modern vessels carry more onboard electronics and mixed-metal assemblies than ever before. With increased marina shore power use, stray current corrosion is becoming more common. A detailed catalogue helps you assess alloy standards, performance curves, and lifespan expectations rather than relying on guesswork. In an AI-driven maintenance world where predictive monitoring is rising, the right data source becomes a strategic advantage.

How often do you revisit your anode selection strategy instead of simply replacing like-for-like?
