Zinc anode & replacement in Clearwater

Short answer: In Clearwater, we check your sacrificial anodes on every dive and replace them in the water once they’re about half consumed — before a spent zinc stops protecting your shafts, props, and trim tabs from galvanic corrosion. No haul-out required.

Why anodes matter in a busy marina

Marinas and canals around Clearwater are full of boats, shore power, and stray current. Sacrificial anodes (zincs) corrode on purpose so your expensive underwater metal doesn’t. Once a zinc is roughly half gone, its protection drops off fast — which is why we flag it then rather than waiting for it to disappear.

How we handle it

Anode condition is part of every recurring hull cleaning at no drama: we note what’s left, and when one hits the replacement point we swap it underwater on a following visit. You approve the parts; we install them without the boat ever leaving the water.

What it costs

In-water hull cleaning is priced per foot of boat length — the fairest measure, because length predicts how much hull, waterline, and running gear a diver has to cover. The recurring rate starts at $3.50/ft for powerboats and $3.00/ft for sailboats & outboards, with monthly minimums of $150 and $120. Length and boat type give you the number; the calculator returns a real estimate in seconds.

Questions boat owners ask

How do I know my anodes need replacing in Clearwater?

When a zinc is about 50% consumed it’s time. We check on every dive and tell you before it becomes a problem.

Can you replace anodes without hauling the boat?

Yes — anode replacement is done in the water at your slip or dock.

Is the anode check included in cleaning?

The check is part of every recurring visit. Replacement parts are a separate, approved cost.
