What does a pre-purchase survey cost in the Solent?

A pre-purchase survey is not the same as an insurance survey. The two are often confused, but they serve different purposes. An insurance survey is produced to satisfy an underwriter that a boat meets a minimum standard for cover. A pre-purchase survey is written for the buyer and gives an honest assessment of condition, value, and anything that needs attention.

A thorough survey will cover the hull and deck (the surveyor taps the hull systematically to identify delamination or osmotic blistering), the keel and keel bolts, deck hardware and fittings, through-hull fittings and seacocks, the bilge and bilge pump, electrical systems, and the interior structure. The rig and engine are typically noted rather than inspected in depth. For either, a specialist may need to be brought in separately if there is any concern.

The survey is usually carried out with the boat hauled out on hard standing. This matters because the condition of the hull below the waterline is one of the most important things to assess on a fibreglass boat, and it cannot be done properly afloat. If a vendor is reluctant to arrange a haulout, treat that as useful information in itself.

The most significant factor is the length of the boat. Surveyors price by size, because a larger boat takes more time. As a rough guide for the Solent area:

• Up to 30 ft: £350 to £550
• 30 to 40 ft: £550 to £900
• Over 40 ft: £900 and upwards

Hull material is also a factor. Fibreglass is the most common and straightforward to assess; steel, aluminium, and timber each require specialist knowledge and generally take longer. An older GRP hull with a history of osmotic treatment may also warrant extra time.

Haulout costs are separate and paid directly to the boatyard. Depending on the yard and the size of the boat, that can add anywhere from £150 to £400 or more. When you are budgeting, it is worth factoring in a day or two on the hard in case the surveyor wants the hull to dry out before making a final assessment on osmosis.

Look for a surveyor who holds membership with the Yacht Designers and Surveyors Association (YDSA) or the International Institute of Marine Surveying (IIMS). Membership does not by itself guarantee quality, but it means the surveyor has met professional standards and carries the indemnity insurance you would want if something gets missed.

In the Solent there are surveyors based across Hamble, Lymington, Southampton, Portsmouth, and the Isle of Wight. Word of mouth is genuinely useful here. If you know other boat owners in the area, asking who they have used and whether they were satisfied is often the quickest route to a reliable recommendation. Sailing clubs and marina forums are worth checking as well.

Check that the surveyor has relevant experience with the type of boat you are looking at. Someone whose work is mainly modern fibreglass cruisers may not be the right choice for a timber pilot cutter or a Dutch steel motor yacht, and it is perfectly reasonable to ask.

Getting two or three quotes is sensible, but be specific about scope when you ask. Some surveyors include an engine check as standard; others treat it as an add-on. If you want the engine included, say so from the start and ask what that covers in practice, since the term can mean anything from a visual check to a running inspection under load.

Avoid choosing purely on price. If a survey misses a serious defect, for example significant osmotic damage, failed keel bolts, or corroded chainplates, the cost of repairs will vastly outweigh whatever you saved on the survey fee.
