A marine surveyor inspects a vessel and its equipment to assess condition, seaworthiness, value and compliance with the intended use. Sailors call a surveyor when they’re buying or selling a boat, making or settling an insurance claim, assessing storm or grounding damage, or wanting an independent condition check before a long trip or refit.
A professional survey covers the hull and structure, deck and superstructure, through‑hull fittings, engines and propulsion, rigging and spars, onboard systems (electrical, plumbing, fuel), safety equipment and fittings specific to the vessel’s type. In Australia a surveyor will also be alert to issues common here: corrosion and galvanic attack in saltwater, osmosis in older fibreglass hulls, timber rot in mid‑coast and northern vessels, and wear on rigs and running gear caused by strong tidal flows and frequent reef contact.
A good survey does three things: it clearly records what was inspected and how, it separates objective facts from opinion, and it gives practical, prioritised recommendations for defects or necessary maintenance. Typical deliverables are a written report with photographs, a condition statement, and any urgent safety advice. The scope, access (in‑water versus hauled out) and cost vary depending on vessel type, size, age and whether the job is a valuation, pre‑purchase inspection, insurance requirement or damage assessment.
Before you engage a marine surveyor, be ready to describe your vessel, what you need from the survey, where the boat will be inspected, and any time constraints. Expect the surveyor to ask for logbooks, service records and previous survey reports if available. Avoid hiring someone who offers to both survey and carry out repairs on the same vessel — that is a conflict of interest and weakens the independence of the report.
