Boat Watch: The International Boat Watch Network (IBWN) was originally founded in 2001 as a public service and tool for the maritime community to share information regarding overdue and missing vessels throughout the world. In mid-2019, the organization was rebranded as "Boat Watch".

Over the years, Boat Watch has become recognized as the authority and repository for information on Overdue, Missing, and Stolen Vessels throughout the world. Boat Watch works closely with the USCG Rescue Coordination Centers around the country and the world.
