Master Mariner
Traditionally, a person holding an unrestricted master's license is called a Master Mariner and may use the postnominal title MM. The term unrestricted indicates that there is no restriction of size, power or geographic location on the license. It is the highest level of professional qualification amongst mariners. In England the term Master Mariner has been in use at least since the 13th century—reflecting the fact that in guild terms, such a person was a master craftsman in this specific profession. In the United States, it was introduced in the mid-19th century. Currently, a U.S. Master Mariner License is reserved for issue to those few who have attained the level of Unlimited Master, as well as Unlimited Chief Engineer, unlike the UK.
An unrestricted master's license is colloquially called a "Master's Ticket", "Master's Unlimited" or just a "Master's." In the UK the official name of a Master Mariner’s qualification has varied over the years. The conventions or acts governing the license have evolved alongside the shipping industry. The master's license is sometimes still referred to as a Class 1 or Master Foreign-Going certificate as it was named during the latter part of the 20th century. The UK Maritime & Coastguard Agency, inline with the amended STCW convention, currently title the license as Master Unlimited.
