Learn why most banks and insurance companies require boat surveys from SAMS- or NAMS-accredited marine surveyors. Discover how this protects your investment and ensures financing and insurance approval.
A marine survey is a professional inspection of a boat to assess its structural integrity, safety systems, value, and overall condition. It's required for:
Financing (pre-purchase survey)
Insurance (insurance survey)
Resale (appraisal survey)
Marine surveyors evaluate everything from the hull and engine to navigation electronics and safety equipment.
You need a marine survey to:
Secure financing from a bank or credit union
Get boat insurance coverage
Uncover hidden defects or safety issues
Validate the vessel’s fair market value
Even if you’re paying in cash, a survey protects you from buying a boat with costly hidden problems.
Most lenders and insurers only accept surveys from accredited marine surveyors, such as:
SAMS (Society of Accredited Marine Surveyors)
NAMS (National Association of Marine Surveyors)
These surveyors follow strict professional guidelines, ethics, and continuing education. Their reports are more reliable, standardized, and legally defensible.
If you're financing your boat, expect your lender to require a survey by a SAMS AMS or NAMS CMS. Without one, they may:
Reject your loan application
Delay the closing
Request another survey at your expense
Most insurance providers will:
Decline to underwrite the vessel without a certified survey
Limit or exclude coverage
Charge higher premiums
Deny future claims if undisclosed issues surface
Hiring a non-certified or underqualified surveyor can lead to serious problems:
| Risk | Consequence |
|---|---|
| Lender rejection | No financing or closing delays |
| Insurance denial | No coverage or higher premiums |
| Inaccurate valuation | You may overpay |
| Missed safety issues | You risk breakdowns or accidents |
| Resale problems | Poor documentation can hurt resale |
