Surveyor
A yacht surveyor is an independent qualified professional who inspects a yacht to assess its condition, value and class compliance. Surveys are typically commissioned at pre-purchase, insurance renewal, post-refit and damage events, and are carried out by accredited members of bodies such as IIMS (International Institute of Marine Surveying) or YDSA.
What is a surveyor?
A surveyor is an independent, qualified professional who inspects a yacht to report on her condition, value, or compliance with class society and flag-state requirements. The surveyor acts for the party commissioning the work, typically the buyer, the insurer, or the owner, and is independent of the broker and the yard. The surveyor's report is the principal technical document on which a purchase decision, an insurance renewal, or a refit acceptance is made.
Several survey types are in regular use. A pre-purchase survey covers condition, machinery, structure, systems, and compliance, and is commissioned by the buyer before contract completion. An insurance survey is required at renewal on older tonnage and focuses on the items material to underwriting risk. A post-refit survey verifies that contracted work has been carried out to specification. A damage survey assesses the cause and scope of a casualty, typically for the insurer. A valuation survey provides a defensible market value for finance, divorce, or estate purposes.
Accreditation runs through several professional bodies. The International Institute of Marine Surveying (IIMS), the Yacht Designers and Surveyors Association (YDSA), and the Society of Accredited Marine Surveyors (SAMS) are the most widely recognised in the superyacht market. Buyers typically retain surveyors who hold membership of at least one of these bodies and who have a documented record on yachts of similar size and complexity.
Why it matters for yacht owners
The surveyor's report is the technical anchor of the transaction. A well-scoped pre-purchase survey typically reveals issues that can be addressed in price negotiation or in seller-funded remedial work before completion. A poorly scoped or rushed survey leaves the buyer exposed to defects that emerge after closing, when remediation costs sit with the new owner. Owners typically treat survey fees as one of the highest-return spends in the acquisition process.

How do I choose a surveyor?
Select on accreditation, experience on yachts of similar size and propulsion type, and independence from the broker. Membership of IIMS, YDSA, or SAMS is a baseline credential. Ask for the surveyor's recent report list (redacted) and references from buyers who have completed transactions in the past two years. Avoid surveyors recommended by the seller's broker without independent verification; the surveyor must be free to flag adverse findings without commercial conflict.
What does a pre-purchase survey cost?
pre-purchase survey fees typically range from the low tens of thousands of euros on a 30-metre yacht to over a hundred thousand euros on a complex 70-metre platform. The fee scales with the yacht's size, complexity, and the scope of inspection (machinery opens, ultrasonic thickness measurement, sea trial). Buyers should treat the fee as small relative to the purchase price and avoid scope reductions that compromise the report's defensibility if issues emerge after closing.
How long does a survey take?
A standard pre-purchase survey on a mid-size yacht typically runs five to ten working days, split between dockside inspection, a haul-out for hull examination, and a sea trial. Larger or more complex yachts can run to three weeks or longer where machinery opens, propulsion shaft inspection, and detailed compliance review are required. The buyer's broker and the surveyor agree the scope and timetable in advance and reflect it in the memorandum of agreement governing the transaction.
Is the surveyor liable if defects are missed?
Surveyors carry professional indemnity insurance, and the engagement letter typically defines the scope of work and the limits of liability. Where a defect is missed within the agreed scope and the surveyor's standard of care, recovery against the surveyor's insurance is possible. However, surveys are not warranties of future condition; latent defects that could not reasonably have been detected at the time of inspection generally fall to the buyer. Engagement terms should be reviewed with maritime counsel before instruction.
