Navy Enlisted Job: Boatswain's Mate
Enlistees Who Haven't Decided on Their Navy Career Path May Choose This Rating
This rating, which has Navy Occupational Specialty code number B400 allows new recruits to enlist without a specific career path identified. It's often used by some enlisted personnel who haven't decided which career to pursue (think of it as a college freshman whose major is still "undecided"), and by others who want a certain rating that may not be available at the time they enlist.
Duties Performed by Boatswain's Mates
Boatswain's mates train, direct and supervise personnel in ship's maintenance duties in all activities relating to marlinspike (a tool used to help tie large knots), deck, boat seamanship painting, upkeep of ship's external structure, rigging, deck equipment and, of course, boats.
Boatswain's mates also operate and maintain equipment which may be used in a variety of areas aboard a ship, including loading and unloading cargo, ammunition, fuel and general stores.
Since this rating is kind of an all-purpose position, the duties are varied and tend to cover work not assigned to other ratings. Boatswain's mates may serve as helmsmen and lookouts, or stand as security watches (both in port and at sea), or serve as part of a damage control, emergency or security alert team.
Their duties may also include repairing, maintaining and stowing equipment in preparation for underway operations; doing temporary duty for 90-120 days with food services divisions or compartment cleaning; working in non-engineering divisions of the ship or station or participating in naval ceremonies.
Working Environment for Boatswain's Mates
After successful completion of recruit training, boatswain's mates are usually assigned to shipboard duties where the Navy needs them the most.
Boatswain's mates can request and may receive on-the-job training for a rating that they are interested in, qualified for and which is available at their first command by completing correspondence courses and personal advancement requirements. They must also be recommended by their commanding officer for the Navy rating they desire.
Although this rating may seem like a jack-of-all-trades job with wildly varied duties, the Navy describes boatswain's mates as the "backbone of every ship's crew."
