Find a marine surveyor

Search by city or state, or zoom the map to your coast, lake or harbor. This is the most complete directory of marine surveyors we know of, built from the SAMS and NAMS rosters and public listings. Where a listing says "Verified", the accreditation was checked against the SAMS or NAMS roster on the date shown. Where it says "Listed, not verified", we found the surveyor in a public directory but have not confirmed an accreditation. Ask any surveyor for their credentials before you hire.

Accreditations shown as Verified were checked against the SAMS and NAMS public rosters on 17 September 2026. Listings marked "Listed, not verified" come from public directories and the surveyor's own website; they are not endorsements. Surveyors can correct or remove a listing at any time from the claim-your-listing page.

Map locations are approximate; confirm a surveyor's area, credentials, and availability with them directly before hiring.
