Frequently asked questions
What if a vessel sinks after I gave it a clean survey?
A vessel loss after a survey can result in a significant professional liability claim. E&O insurance covers your defense when buyers or insurers claim your survey missed critical defects.
Do marine surveyors need special certifications?
NAMS (National Association of Marine Surveyors) and SAMS (Society of Accredited Marine Surveyors) certifications are widely recognized. Some insurers require professional association membership.
Am I covered for surveys on large commercial vessels?
Coverage limits should match the value of vessels you survey. If you survey high-value commercial vessels, ensure your E&O limits are adequate — vessel values can be in the millions.
How to get the best rate
The fastest way to find the lowest rate is to compare multiple carriers side by side. Most marine surveyors can get quotes from 3–5 insurers in under 10 minutes and receive their certificate of insurance the same day.
