Seamen
Seaman is a naval rank and is either the lowest or one of the lowest ranks in most navies around the world. In the Commonwealth it is the lowest rank in the navy. The next rank up is able seaman, followed by leading seaman, which is followed by the petty officer ranks.
In the United States, it means the lowest three enlisted rates of the U.S. Navy and U.S. Coast Guard, followed by the higher petty officer ranks. The equivalent of the seaman is the matelot in French-speaking countries, and Matrose in German-speaking countries.
The term "seaman" is also a general-purpose for a man or a woman who works anywhere on board a modern ship, including in the engine spaces, which is the very opposite of sailing. This is untrue in the US Navy where a sailor might be a seaman but not all US Navy sailors are a 'Seaman' as they might be an Airman, Fireman, Contructionman, or Hospital Corpsman. Furthermore, "seaman" is a short form for the status of an "able-bodied seaman," either in the navies or in the merchant marines. An able-bodied seaman is one who is fully trained and qualified to work on the decks and superstructure of modern ships, even during foul weather, whereas less-qualified sailors are restricted to remaining within the ship during times of foul weather — lest they be swept overboard by the stormy seas or by the high winds.
There are 4 grades of seaman/matelot in the Royal Canadian Navy:
Ordinary seaman or matelot de troisième classe
Able seaman or matelot de deuxième classe
Leading seaman or matelot de première classe
Master seaman or matelot-chef
The rank of master seaman is unique because it was created only for the Canadian Navy. It does not follow the British tradition of other Canadian ranks. It corresponds to the rank of master corporal/caporal-chef.
Matelot 2e classe (seaman 2nd class), or apprentice seaman, and matelot breveté (able seaman) are designations of the French Navy. Matelots are colloquially known as "mousses".
