Pre-purchase survey
An independent technical inspection commissioned by the buyer before contract. Distinct from the seller's most recent survey and almost always worth the cost.
A pre-purchase survey covers structural, mechanical, electrical, and operational systems, typically over four to seven days afloat plus a haul-out. Cost on a 40 to 50 metre yacht runs USD 25,000 to 60,000 inclusive of paint specialist and class-society inspector. The buyer engages the surveyor directly, and the surveyor's fee is paid by the buyer regardless of whether the deal closes.
