Every US Coast Guard–documented vessel (~394,495) — recreational, commercial fishing, freight barge, passenger, towing and more — with name, official number, IMO, call sign, service, flag, gross/net tonnage, dimensions, hailing port, builder & build year, propulsion, hull material, and certificate-of-documentation status plus trade endorsements. Vessel/asset attributes only — owner names and addresses are deliberately dropped (the source's redaction is partial, so the entire owner block is excluded) — ZERO PII. Searchable by vessel name or official number, with a canonical /vessel/{vessel_id} page each. From USCG 'Merchant Vessels of the United States' bulk (Akamai-gated; institution/asset level).
