Equasis

Equasis Ship and Company Search

Free registered-user web lookup for safety-related information on named ships and companies. Registration explicitly accepts Insurer as a sector; this source is web lookup only and offers no documented API, batch enrichment, or full-file delivery.

United States Coast Guard

Port State Information Exchange (PSIX)

Weekly public FOIA snapshot derived from MISLE for U.S.-flag vessels, foreign vessels in U.S. waters and Coast Guard contacts. PSIX—not MISLE—is the admitted public product; it provides vessel search, XML web services and XLSX exports of inspection, operational-control and deficiency data.

Sea-web

Commercial online maritime reference platform integrating ship particulars, current and historical ownership, companies, ports, movements, casualties, performance and security modules.
