Q: WHAT DO BOATSWAIN'S MATES DO IN THE NAVY?

A: Boatswain's Mates train, direct and supervise others in marlinspike, boat and deck seamanship: ensure proper upkeep of the ship's external structure, rigging, deck equipment and boats; lead working parties; perform seamanship tasks; are in charge of picketboats, self propelled barges, tugs and other yard and district craft; serve in or in charge of gun crews and damage control parties; use and maintain equipment for loading and unloading cargo, ammunition, food and general stores.

 

Q: WHAT IS THE HISTORY OF THE BOATSWAIN'S MATE?

A: The early Boatswain was appointed Warrant, and was among the most important men on board ship. He was usually a grizzled old salt who wasn't timid about giving orders and it never occurred to him that they wouldn't be obeyed. He was assisted by his mates, or Boatswain's Mates, and though it was unlikely that he was unrecognizable, he nevertheless carried a silver Bosn’s pipe and rattan cane that identified his position. His pipe was the sailing ship's PA system. It could be heard 120 feet up in the rigging and in the deepest and darkest hold. His cane was an instrument of persuasion which it was said, cured more scurvy than the doctor, made cripples take up their beds and walk, and made the lame skip and run up the shrouds like monkeys...

As you may know, the Boatswain's Mate play an extremely important role in replenishment at sea in today's Navy. However, transfer-at-sea methods were actually used as early as 1804. During the war with Tripoli, for example, the ketch Intrepid transferred a cargo of fresh provisions to USS Constitution, which was engaged in enforcing a continental blockade of the port of Tripoli. This cargo included four bullocks, one calf, 13 pigs, 300 pounds of hay, two baskets of peas, and three casks of old Hock. This maneuver was the springboard for the modern, mobile logistical support now provided through underway replenishment that enables the fleet to remain at sea almost indefinitely.

Not all ratings of this early era have retained their identity, because the majority of our ratings today resulted from later technical developments. While jobs and duties have changed, the rating titles of Boatswain's Mates, Quartermasters and Gunner's Mates have remained the same since the American Revolution.
