Start with an inventory
Identify the anodes specified for your boat and its installed equipment. Use the relevant manuals or ask a competent technician to help establish the list. Do not assume that one visible hull anode represents every anode on the boat.
For each location, record the equipment it relates to, the specified part and the last known replacement date. Mark unknown information as unknown. A guessed installation date creates false confidence in the next inspection.
Record the observation consistently
Ask for a clear image of the anode and its location. Keep the viewpoint similar at later visits where possible. Note visible consumption, damage or an uncertain attachment, without turning a photograph into a definitive electrical diagnosis.
Anode choice and replacement requirements depend on the equipment and installation. Confirm the correct specification and replacement criteria with the manufacturer or technician. Do not select a material or part solely because another boat uses it.
Investigate a change in pattern
If the condition differs markedly from previous visits, show the history to the technician. Include changes in berth, equipment or work on the boat when relevant. The record helps frame a question; it does not establish the cause.
Avoid treating replacement as the complete answer to unexplained rapid deterioration. Ask whether further assessment is needed and record the recommendation. Equally, do not assume that an anode that appears little changed proves the system is functioning correctly.
Close the work record
After replacement, save the part specification, date and a photograph. Link that entry to the equipment record and note any further investigation. Keep inspection findings separate from completed work so there is no ambiguity about what was actually replaced.
For an owner away from the boat, ask the report to identify the next action plainly: no further action within the agreed check, replacement proposed, or investigation required. That is more useful than an unexplained photograph captioned ‘anode checked’.
The record should help a competent person compare condition and make the next decision. It is not an electrical diagnosis.
