Look up vessels in the US Coast Guard PSIX registry by name (partial match), call sign, official number, hull number (HIN), flag country, service type, or build year. Returns matching vessels with the USCG vessel id, name, call sign, service type, build year, status, official number, HIN, and flag. Keyless, public-domain. Covers US-flagged vessels (and foreign vessels with US port-state-control activity). Pair the returned vesselId with maritime.cases for the inspection record. (Cross-references trade.locode for ports.)
