Boat survey cost: what actually drives a marine surveyor's fee

Why nobody publishes a price list

There is no statutory or professional fee scale for marine surveying in the UK, and the profession itself does not pretend otherwise. The International Institute of Marine Surveying tells boat owners plainly that "survey prices can vary hugely so you may want to get a couple of quotes before choosing a marine surveyor", and adds that "sometimes the cheapest may not always be the best" (IIMS, choosing a marine surveyor). Getting two or three quotes for the same defined scope is the correct move, and the phrase "for the same defined scope" is doing most of the work in that sentence.

The variables that move the number

Length and size

The most obvious driver. A larger vessel has more hull to sound, more systems to test and more accommodation to inspect. Many surveyors quote by length overall; some quote by tonnage, particularly for commercial and larger craft. Ask which basis a quote uses before comparing two.

Construction material

GRP, steel, aluminium, timber and ferrocement are inspected differently and carry different failure modes. A timber hull and a steel hull of the same length are not the same day's work.

Complexity of systems

Twin diesels, generators, bow thrusters, hydraulics, complex electrics and integrated electronics all add inspection time. A simple day-sailer and a heavily equipped motor yacht of similar length differ substantially.

Travel

Travel time is part of a surveyor's chargeable day. A boat two hours from the nearest suitable surveyor costs more to survey than the same boat on their doorstep, and overseas inspections add flights and accommodation.

Access and condition

Lockers full of gear, an unstepped mast, or a boat that cannot be got to are all time. Emptying the vessel before the surveyor arrives is the cheapest thing an owner or vendor can do.

The report itself

The YDSA describes a full condition report as identifying the craft, outlining the extent and limitations of the inspection, then giving a full description of the inspection and any defects found, "together with graded recommendations identifying when action is needed" (YDSA, types of survey). Writing that up properly is a substantial part of the job and is not visible on the day.

The bills that are not the surveyor's

• The yard lift and pressure wash. A hull inspection normally requires the vessel ashore. The boatyard charges lifting, washing and any time in the slings or on the hard, and that is usually the buyer's cost rather than the vendor's. This is standard market practice rather than a statutory rule, so agree in advance who is paying and confirm the yard's charges directly with the yard.
• Engine survey. Where a separate marine engineer inspects machinery, that is a second fee. Some surveyors include a functional check of machinery; a full engine survey is a different piece of work.
• Sea trial. If you want the vessel run under load, arranging and attending a trial is additional time for everyone involved.
• Further investigation. The YDSA notes that a limited scope survey may follow a pre-purchase survey "where the surveyor had identified a problem with a particular system or area such as the engines or the electrics, and a closer investigation is required by a specialist".

The credentials question, since the work is unregulated

The IIMS is direct about the state of the profession: "Choosing a yacht and small craft marine surveyor can be a difficult job as the industry, bizarrely, remains largely unregulated despite attempts to persuade the authorities otherwise." It also places a specific duty on you: "It is your responsibility to ensure and satisfy yourself when engaging an IIMS UK member surveyor that you ask them to confirm their PI insurance cover is current and adequate." Ask for that confirmation in writing, along with the surveyor's qualifications and their experience of your type and size of vessel.

The RYA's guidance for buyers is to get the boat surveyed after viewing and having an offer accepted, noting the report "may identify problems that justify renegotiation of the price" (RYA, boat buying made easy).

Compare quotes on scope, not on headline fee. A cheaper quote that omits an out-of-water inspection, or that excludes the written report you actually need for insurance or finance, is not cheaper.
