Before travelling
Ask for the boat identity, build year, ownership evidence, CE documents and known damage before visiting. This reveals inconsistencies early and helps focus the inspection.
Create a candidate record for the listing, seller statements, appointment and your own observations. Listings change; preserve the state on which your decision is based.
Stay systematic on board
Work in a fixed sequence across hull, keel, rudder, deck, rig, engine, electrical, plumbing, gas and safety equipment. Photographs should retain location and context.
A clean interior is not proof of technical condition. Note smells, moisture, corrosion, local fresh paint and inaccessible systems.
Sea trial and survey
A sea trial reveals handling, engine behaviour, vibration, steering and system interaction, but it does not replace inspection ashore.
For a serious candidate, commission an independent survey with an agreed scope. Survey cost is part of purchase due diligence.
Turn findings into a decision
Classify findings as immediately safety-critical, short-term, planned or cosmetic. Add realistic cost ranges including access, labour and consequential damage.
Decide on the actual boat rather than model reputation. Condition, history and traceable documents determine the individual purchase.
An example of an evidence-based finding
Suppose an elevated moisture reading appears in the foredeck. A defensible note does not say “deck leak”; it records the location, instrument, comparison reading, visible traces and weather. Cause, remedy and price remain separate open questions so a surveyor can assess the evidence without inheriting a premature diagnosis.
Give each finding four decision fields: possible safety impact, next inspection step, cost range and whether purchase depends on resolution. A missing extinguisher and an uncertain keel repair remain visible without being treated as equivalent risks.
When to stop or involve a professional
Stop your own inspection where access is unsafe or work on gas, shore power, rig, steering, structure or fuel would be required. A viewing is neither a repair nor permission to dismantle another person’s systems.
Unclear identity, conflicting ownership evidence, unexplained major damage or pressure for immediate payment justify pausing the decision. Independent survey cost is part of risk assessment in that situation, not merely an add-on.
General information, not a survey or legal, tax or financial advice.
