Coast Guard Marine Safety Manual, Volume V, Investigations and Enforcement, COMDTINST M16000.10A, which is the most current version. The Marine Safety Manual (MSM) is the primary policy and procedural statement for the marine safety programs of the Coast Guard. Published for the use of all Coast Guard marine safety and industry personnel, it prescribes the essential functions which must be performed to attain the overall objectives of the Commercial Vessel Safety CVS and Port and Environmental Safety, Marine Environmental Response, and Waterways Management PES/MER/WWM Programs and certain investigative functions of the Recreational Boating Safety RBS Program. The MSM should be used as a guide for consistent and uniform administration of marine safety activities, without undue hampering of independent action and judgment by marine safety personnel. Volume 5 of this manual established policies and procedures for the activities associated with the investigation of marine casualties, investigation into recreational boating deaths, detecting violations of criminal and other statutes for law enforcement purposes, taking remedial law enforcement action such as civil penalties and suspension and revocation, investigating pollution, and enforcing international treaties.
