The Honourable Company of Master Mariners is one of the livery companies of the City of London.[1] While the other livery companies are entitled to the style Worshipful,[1] the Master Mariners are styled Honourable, King George V having granted them that honour in 1928.
The Company aids nautical schools and promotes nautical research. Members meet regularly to socialise, discuss technical issues and assist with the mentoring and training of young officers, who will train at sea to reach master mariner status.[2]
The Honourable Company ranks seventy-eighth in the order of precedence for livery companies. Its motto is Loyalty and Service. The organisation nominally has the right to allow two of its Masters to serve as nautical assessors in the Admiralty Court.[3][4]
The company works with other industry organisations such as the International Federation of Shipmasters' Associations.[5] This includes the organisations of lectures and command seminars.[5]
