Why Are My Anodes Disappearing So Fast?
This week Impavidus comes out of the water for the usual haul-out jobs — cleaning back the Coppercoat, polishing the topsides and checking everything underneath the boat.
But while inspecting the underwater gear, we discovered something that genuinely surprised me.
One set of anodes was disappearing far faster than expected… and the reason turned out to be something I suspect many saildrive and shaft-drive owners may never even have considered.
In this video we look at:
⚓ Saildrive and propeller anodes
⚓ Zinc vs aluminium anodes
⚓ Rope cutters and electrical continuity
⚓ Galvanic corrosion explained simply
⚓ Why some anodes disappear much faster than others
⚓ The importance of electrically isolated propellers
We also explain how certain rope cutter and shaft arrangements can unintentionally create an electrical path between underwater components, dramatically changing how the protection system behaves.
As always, this is a real-world investigation aboard SV Impavidus — practical engineering, diagnostics and problem-solving aboard a liveaboard cruising yacht.
