1. The Complexity of the Superyates: It is not a Yacht, it is a Fleet Villa
When we cross the threshold of 40 meters of ridge, we stop talking about “yachts” to enter the world of the superyachts. On this scale, the boat becomes a complex industrial installation: twin or triple propulsion systems, high capacity generating plants, state-of-the-art navigation systems, exotic materials interiors and a crew of up to 15 people.
An error in pre-purchase inspection of an asset of 15 to 50 million euros is not a mere expense of repair; it is a devastating loss of property and a legal risk to the owner. Therefore, in Prop Trust Verified, we apply a military-grade inspection protocol, adapted to the standards of the main classified companies (Lloyd’s Register, DNV, ABS).
2. The 4 Critical Phases of Our Inspection
Our process of technical due diligence for superyachts is divided into four inescapable phases. To omit any of them is to take an unacceptable risk.
Phase 1: Documentary and Classification Audit
Before putting a foot on board, our team analyzes the full asset history:
- Clasifier reports: Review of status notes, outstanding recommendations and status of statutory certificates (SOLAS, MARPOL, MLC).
- Maintenance History (PMS): Has the Planned Maintenance System been followed by the manufacturer? A PMS a day is the best indicator of a responsible owner.
- Sinestrality record: Search in international databases (Equasis, IHS Sea-web) to detect preheating, collision or fires.
Phase 2: Structural and Cascos Inspection (Hull & Superstructure)
In steel and aluminum superyachts, corrosion is the silent enemy. Our team uses:
- Measurement of ultrasound thicknesses (UT): Complete mapping of critical areas (floor line, welding areas, ballast tanks).
- Welding inspection: Use of penetrating dyes and magnetic particles to detect microfissures in structural unions.
- Analysis of painting and antifouling: Evaluation of the state of the cathodic protection system (sacrifice anodes or ICCP systems).
Phase 3: Mechanical, Electrical and Navigation Systems (M ChildhoodE)
The heart and brain of the superyate. We inspected:
- Propulsion: Oil analysis of main engines and generators (certified laboratory). Endoscopic inspection of cylinders if necessary.
- Electrical systems: Infrared termography of electrical panels to detect hot spots and fire hazards. Cable insulation tests.
- Electronics and Navigation: Verification of the calibration and operation of radars, echo sound, AIS and satellite communication systems (VSAT, FleetBroadband).
Phase 4: Mar Tests (Sea Trials) and Tripling Interviews
The role holds everything, the sea doesn’t. Sea tests are mandatory and should include:
- Speed and consumption tests to different RPM regimens.
- Maneuverability tests ( 360 degrees, emergency stop).
- Verification of stability and behaviour at sea.
- Confidential interviews with the Captain and Chief of Machines: Often, the crew knows the “skeletons in the closet” that the broker hides. Our experience allows us to extract this information with tact and professionalism.
◾ The Human Factor: The Importance of Tripling
In our experience of more than 30 years, 40% of the serious flaws in second-hand superyachts are not detected in physical inspection, but through interviews with the crew. An honest captain, under a confidentiality agreement (NDA), can save you from a disastrous purchase.

4. Conclusion: The Quietness of Technical Excellence
The purchase of a superyate is one of the most complex financial decisions a Family Office can make. Do not let the emotion of the moment cloud the technical rigor that your heritage demands.
In Prop Trust Verified, we combine the technical experience of senior naval engineers with the legal knowledge of international maritime arbitration. Our report not only tells you the status of the boat; it gives you the necessary ammunition to negotiate the price, require repairs or, if necessary, withdraw from the operation on time.
