Purchasing a pre-owned yacht represents a significant investment that requires a thorough technical assessment to avoid unpleasant surprises. Here are the 5 checks an independent marine surveyor should always carry out before closing the deal.
1. Structural hull inspection
The hull condition is the most critical parameter. Through visual inspection and ultrasound testing, it is possible to identify delaminations, osmosis, blistering or localized thinning that compromise the safety and value of the vessel.
2. Paint cycle assessment
The anti-corrosion protection system (antifouling, primer, undercoat, topcoat) must be analyzed with professional instruments. Insufficient thickness, inadequate adhesion or incompatible products can generate very high restoration costs.
3. Onboard systems verification
Electrical systems, hydraulics, engines, generators and safety systems: each component must be verified under operating conditions. Particular attention should be paid to shaft alignment, abnormal vibrations and overall energy balance.
4. Document review
Class certificates, insurance, flag, CE compliance, navigation booklet: documentation must be complete, up-to-date and consistent with the actual condition of the vessel.
5. Sea trial
A sea trial allows you to verify the dynamic behavior of the vessel, fuel consumption, noise and vibration levels, and the response of steering and safety systems under real conditions.
