What is a ship rider?

Ship riders are personnel from one country who are authorized to embark on the vessels of another country, typically as part of cooperative maritime law enforcement or security operations. Their main role is to observe, advise, and sometimes assist in enforcing laws in areas like fisheries, customs, and counter-narcotics. Ship rider agreements help strengthen international partnerships and improve maritime domain awareness. These individuals are usually granted authority to act under the host vessel’s jurisdiction, enhancing legal cooperation and operational effectiveness.
