Source: U.S. Coast Guard 'Merchant Vessels of the United States' (MISLE/VDS), a US federal public-domain file (17 U.S.C. § 105) covering vessels holding a US Certificate of Documentation — commercial and documented recreational vessels; foreign-flag and state-registered-only vessels are NOT covered. Owner names and addresses were removed from the public file by the USCG in 2017, so this API cannot identify a vessel's owner; for ownership or title, request an Abstract of Title from the National Vessel Documentation Center.
