Begin with the reason for the visit
Describe the observation rather than selecting a procedure immediately. Has performance changed? Is an anode due for inspection? Is there visible growth, or did an incident prompt concern? Give dates, recent work and any relevant photographs.
A change in speed or vibration does not establish a single cause. Avoid asking someone simply to confirm your diagnosis. Ask what they can inspect and what would require another type of assessment.
Ask what the inspection will cover
Request a clear list of areas: hull, propeller, visible fittings and identified anodes, for example. Ask how visibility and access will be recorded. A useful report names areas that could not be inspected rather than leaving silence to imply they were satisfactory.
Photographs should be labelled by location and date. If an image is unclear, the report should explain the limitation. An underwater photograph is evidence of what was visible at that moment, not a complete assessment of every component or the structure behind it.
Treat cleaning as a separate decision
Inspection and cleaning are different scopes. Before cleaning, identify the coating and confirm that the proposed method is compatible with its instructions and permitted at the location. International’s antifouling guidance distinguishes coating types and their treatment; there is no universal scrubbing method for every finish.
Do not undertake work in the water merely because it appears convenient. Access, operating conditions and local requirements can make an alternative necessary. Have the provider explain what is feasible before agreeing the work.
Define the decision after the report
Ask for findings, uncertainties and recommended next steps. Some observations may justify monitoring; others may need access ashore or a specialist. Agree who will decide and obtain approval for additional work.
If a fault affects safe operation, a reassuring appearance alone is not enough to clear the boat for use. Keep the observation open until it has been assessed appropriately. The value of the inspection is a better decision, including a decision that more investigation is needed.
A good inspection explains both its findings and its limits.
