noun
mariner
MAIR-ih-ner/ˈmærɪnər/
A person who works aboard a ship at sea.
The mariner hauls a line into a neat coil on the ship's deck.

Etymology
The base means “of the sea,” and the added ending identifies a person associated with it. That relationship became occupational: a mariner directs or helps navigate a ship.
In context
the becalmed or wind bound mariner is the skill that assures him he is exactly ninety- three leagues and a quarter from his port?
