An Insurance Marine Survey is a professional inspection of a boat or yacht conducted primarily to help an insurance company evaluate the vessel’s condition, seaworthiness, and risk level before issuing or renewing coverage.

Unlike a pre-purchase survey, which is designed to help a buyer make an informed purchasing decision, an insurance survey focuses on whether the vessel presents an acceptable risk to the insurer.

Purpose of an Insurance Marine Survey
Insurance companies may require a survey to:

• Determine the vessel’s overall condition
• Identify safety hazards or deficiencies
• Verify that the boat is seaworthy
• Establish an insurable value
• Assess the likelihood of future claims
• Decide whether to issue, renew, or modify coverage

When an Insurance Survey Is Required
Insurers commonly request one when:

• A vessel is older (often 10–20 years or more)
• Coverage is being obtained for the first time
• The vessel has changed ownership
• The boat is particularly valuable
• Coverage limits are being increased
• A previous survey is outdated

Benefits of an Insurance Marine Survey
Even though it is conducted for insurance purposes, the survey can help owners:

• Identify safety concerns before they become serious
• Reduce the likelihood of breakdowns or accidents
• Document the vessel’s condition
• Support accurate insurance valuation
• Improve insurability and potentially avoid coverage issues

In short, an insurance marine survey is a condition-and-risk assessment that helps insurers determine whether a boat is an acceptable risk to insure and what coverage terms should apply.
