Pre-Purchase Marine Survey

What Is a Pre-Purchase Marine Survey?

Before purchasing a vessel, it is essential to conduct a thorough, independent evaluation. A pre-purchase marine survey is the most detailed and comprehensive type of marine inspection available, helping you make a well-informed buying decision.

As experienced marine surveyors, Atlantic Marine Group inspects every major system on board, both above and below the waterline. From hull condition and engine performance to electrical safety and hidden signs of wear, we examine every aspect that could impact safety, value, or reliability. Whether you are buying your first boat or your fifth, this survey helps ensure the vessel is safe, seaworthy, and worth the asking price.

Our pre-purchase survey includes, but is not limited to, the following:

  • Hull and Deck Inspection
    We check for structural issues, past repairs, water intrusion, and overall condition above and below the waterline.

  • Moisture Testing
    Finds trapped moisture in decks, stringers, and core materials that can lead to long-term damage.

  • In-Water and Out-of-Water Review
    Includes hull inspection during haul-out, with percussion testing to identify hidden damage or delamination.

  • Engine Diagnostics and Blow-by Testing
    Computer scans (when available), oil condition, and performance testing to evaluate engine health.

  • Oil and Coolant Sampling
    Lab testing detects internal engine wear, contamination, and signs of overheating.

  • Transmission and Generator Checks
    Visual and operational checks to catch early-stage mechanical issues.

  • Electrical System Evaluation
    Review of wiring, breakers, battery systems, grounding, and signs of corrosion or overload.

  • Corrosion and Stray Current Testing
    Protects against hidden electrical issues that can damage underwater metals.

  • Rigging and Sail Inspection (for sailboats)
    Drone or bosun chair inspection of rigging, spars, and sails for signs of wear or stress.

  • Thermal Imaging and Remote Camera Review
    Identifies overheating components or water damage behind walls and panels.

  • Safety System Checks
    CO and gas leak detection, proper placement of extinguishers, alarms, and engine room ventilation.

  • Sea Trial (Optional)
    Includes full-throttle testing, system response under load, and helm performance.

  • Deficiency Report with Recommendations
    Clear, organized report outlining any issues found, from minor concerns to safety-related findings.

  • Valuation
    Includes fair market value, replacement cost, and an overall condition summary.

Buying a boat is a significant decision, and having a full understanding of the vessel’s condition helps you make that decision with confidence. Whether it’s a local South Florida purchase or a boat located overseas, we provide the clarity and assurance you need to make a confident and informed decision.
