Also a little note here: At work, the sailors mostly call eachother by the name of their boats. Except they have a close relationship, like being friends, siblings or parent-child. Then they can use the other's real name.
Of course there are cases the sailor has a nickname already and then it turns to be the same as it'# boat. Like Warrior, Zebedee or Hercules.
And others where the boat's name inspires the sailor's prefered nickname, like Ten Cents, Sunshine or Big Mac.
Anyway, out of work, those who aren't very close but work together in the port (not necessarily in the same fleet) tend to call eachother by their boats' names, that's the whole point.
