Photo 1: a brand-new rudder anode. If it later “disappears,” that’s usually proof the protection is working.
Photo 2: the same rudder anode after real use. Consumption is expected. The pattern of wear is what matters.

Ever had a customer message: “Your anode is disappearing”?
That’s usually the best sign you can get.
That “missing metal” is the job.
It means the anode is sacrificing itself so the hardware doesn’t.

Photo 2: the same type after real use (visibly ~30-40% consumed).
Where distributors get burned isn’t the concept.
It’s the diagnosis. Misdiagnose it and you get refunds, credit notes, and hours of back-and-forth.
A simple wear check when a yard calls:
- Even wear = normal. It’s working.
- Still shiny after time in the water = often poor contact, paint where it shouldn’t be, wrong fit, or incorrect alloy for conditions.
- Fast and uneven loss = possible stray current or harsh conditions.
When a customer sends a “used anode” photo, ask these questions:
- Where was it installed? (rudder/shaft/hull)
- How long was it in the water?
- Was the contact surface clean metal-to-metal?
- Which anode material (zinc/aluminum/magnesium)?
- Which water (salt/fresh/brackish)?
Based on these answers you can address most cases in polite, constructive conversations, instead of hours of tedious back-and-forth.
If you want the 1-page wear guide we send to distributors, send SEND IT to gvapo@nauticalarmor.com and I’ll share it.
