Survey Procedures and Policies






Scope of survey includes:

  • Survey vessels to ABYC and federal standards where possible. Some of these standards are not found on boats built outside the US;
  • Inspect all areas and equipment including sails, rig, machinery and electronics, report condition;
  • Sea trial vessel when possible;
  • If significant problems exist, I will suggest involving an appropriate specialist;
  • The survey document reports on the structural condition of the vessel and all equipment and lists recommendations to correct any problems.
Vessel Valuation

  • Determine value based on survey results and comparisons with other boats. I also consult experienced yacht brokers and trade publications.
Survey methods and equipment

  • All testing is non-destructive. Destructive testing must be approved by all parties;
  • Visual inspection of hull, decks and all equipment and surface finishes;
  • Testing of composite hulls by the following:
  • Barcol hardness measurement;
  • Hammer tapping or 'sounding' of all fiberglass or carbon surfaces to check for softness, repairs, delamination, blistering, cracking or crazing;
  • Moisture content measurement using a moisture meter for hull and deck laminates;
  • System testing;
  • Audio gauge thickness testing for steel and aluminum vessels;
  • All information and findings are contained in the survey report.

Seller or sellers broker should:

  • Disclose all history of the boat;
