BM – Boatswain's Mate
A boatswain's mate (BM) is the most versatile member of the Coast Guard's operational team, and a master of seamanship. BMs are capable of performing almost any task in connection with deck maintenance, small boat operations, navigation, and supervising all personnel assigned to a ship's deck force or shore unit. BMs are in charge of the newest Coast Guard small boats while conducting search and rescue, aids to navigation, law enforcement and security operations. BMs operate hoists, cranes, and winches to load cargo or set gangplanks, stand watch for security, navigation, or communications, and have a general knowledge of ropes and cables, including different uses, stresses, strains, and proper stowing.
