I have been wondering about the term ‘master mariner’. An official definition is: “A Master Mariner is the professional qualification required for someone to serve as the Captain of a commercial vessel of any size, of any type, operating anywhere in the world.”
I’m not thinking of the official qualification, designed to satisfy a regulating authority, I’m thinking of what it takes to be a master mariner in sailing vessels like ‘Ceres’ and ‘Bessie Ellen’.
