Our Core Survey Services

1. Pre-Purchase Condition & Valuation Survey

The ultimate risk mitigation for yacht buyers.

A rigorous, bow-to-stern inspection designed to uncover hidden defects before a transaction. This helps you fulfill your legal "duty of inspection" while providing a complete overview of the vessel's true state.

Includes: Moisture mapping, osmosis screening, rig inspection (deck level), electrical system overview, and sea trial.
Deliverable: A legally robust, detailed condition report and current market valuation.

2. Forensic Damage & Insurance Surveys

When catastrophic failures, groundings, or complex material fatigue occur, visual inspections are not enough. We conduct deep-dive forensic analyses to determine the exact cause and extent of the damage, providing irrefutable documentation for insurance claims, repair yards, and legal disputes.For lawyers and clients requiring indisputable evidence in court proceedings, please visit our dedicated portal for Marine Expert Witness Testimony

3. Advanced NDT (Non-Destructive Testing) & Ultrasound

Seeing beyond the surface.

Pioneering the use of systematic hull diagnostics, we utilize advanced ultrasonic thickness measurement (UTM) and NDT techniques. This ensures absolute certainty regarding plate thickness, hidden corrosion, and internal structural voids in steel, aluminum, and GRP hulls without compromising the vessel.

4. Digital ECU & Engine Diagnostics

Uncovering the true history of your powertrain.

Modern marine engines require digital solutions. Using state-of-the-art diagnostic software, we extract live data, fault codes, and historical operational profiles directly from the Engine Control Unit (ECU). We identify over-revving, thermal events, and hidden sensor failures that a standard mechanical visual inspection will miss.

Investment & Booking

A premium survey is performed as a rigorous consulting assignment under absolute professional liability. Our baseline pricing serves as a comprehensive guide, inclusive of VAT, land/sea inspection, and the final written report.
