The British Merchant Navy is the collective name given to British civilian ships and their associated crews, including officers and ratings. In the UK, it is simply referred to as the Merchant Navy or MN. Merchant Navy vessels fly the Red Ensign and the ships and crew are regulated by the Maritime and Coastguard Agency (MCA), a specialist agency of the UK Department of Transport. British merchant ships are registered under the UK or Red Ensign group ship registries. British Merchant Navy deck officers and ratings are certificated and trained according to STCW Convention and the syllabus of the Merchant Navy Training Board in maritime colleges and other training institutes around the UK.

A boatswain, bo's'n, bos'n, or bosun, also known as a deck boss, or a qualified member of the deck department, is the most senior rate of the deck department and is responsible for the components of a ship's hull. The boatswain supervises the other members of the ship's deck department, and typically is not a watchstander, except on vessels with small crews. Additional duties vary depending upon ship, crew, and circumstances.
