The Truth About Surveys

A marine survey is a comprehensive condition assessment of a vessel — structural, mechanical, electrical, and safety-related.

It is not a pass/fail. It is not a guarantee of perfection. It is not a substitute for sound judgment.

What a proper survey does is give you real, documented information about a vessel's actual condition — so you can negotiate from facts, not hope.

Most buyers overpay, overlook critical deficiencies, or walk into costly problems because they skipped independent inspection or relied on the word of someone motivated to close the deal.

A good survey changes the dynamic entirely.

Scope of Inspection
  • Hull, deck, and structural components
  • Keel, rudder, and underwater gear
  • Standing and running rigging (sailboats)
  • Engine, propulsion, and mechanical systems
  • Electrical systems (AC and DC)
  • Fuel systems and tanks
  • Plumbing, sanitation, and bilge systems
  • Through-hulls, seacocks, and fittings
  • Safety equipment and gear
  • Interior condition and moisture evaluation
  • Sea trial observation (when applicable)
  • Haul-out and bottom inspection

Scope varies by vessel type, size, and purpose of survey. Contact for details.

Frequently Asked Questions
How is a formal marine survey different from a Vessel Inspection (Pre-Purchase)?

A formal survey is an in-person, credentialed condition assessment — often required by lenders and insurers, and typically documented for financing or insurance purposes. The Vessel Inspection (Pre-Purchase) is a lower-cost virtual walkthrough used earlier in a search, before committing to travel or a formal survey.

Does a survey mean a boat passes or fails?

No. A survey isn't a pass/fail grade — it's documented, factual information about the vessel's actual condition, so you can negotiate or decide with real data instead of hope.

Where are in-person surveys available?

Currently in the San Francisco Bay Area. Inquire directly for scheduling and availability outside that region.

Do I need a survey for insurance or financing?

Most lenders and insurers require a documented condition and value survey before approving financing or coverage. A Condition & Value Survey or Insurance Survey covers that requirement.
