Are there any female sailors?

There are female sailors, but the number is very small.

When the landlord says passenger ship, it is necessary to make it clear whether the job is to recruit a waitress or a sailor. To put it simply, seafarers belong to navigation and waiters belong to service (just like pilots and stewardesses on airplanes), which are two different jobs.

Whether a waitress or a sailor needs special training, the treatment is different.
