There seems to be a bit of confused information about the term “Master Mariner” and I’d like to see what the forum members think about it.
Most dictionaries define a master mariner as a ship’s master. Wikipedia says that in the British tradition, it means someone with a master unlimited oceans ticket. In the US, Wiki continues, says that “Master Mariner” is a person with the Master Unlimited ocean as well as unlimited Chief Engineer.
From my experience at sea, is that when you say “master mariner” you mean the Master and CE tickets, which means that there are very few indeed (I have met two so far). When I go back to my academy, I see that anyone who has a Master Unlimited is called “master mariner.”
In my opinion, you use the term “captain” for the person in command of a vessel no matter the size, “master” for those with have a master unlimited license, and “master mariner” for those with both top licenses.
So what says the board?
