Navigator

A navigator is the person onboard a ship responsible for the navigation of the vessel. The navigator's responsibilities include planning the journey, advising the captain (or pilot) while en route, and ensuring that hazards or obstacles are avoided.

Navigators in One Piece
In One Piece, navigators are the most crucial members of a ship, especially when traveling the Grand Line. A ship is only as good as the navigator that directs it. Otherwise, the ship will be damaged or shipwrecked by unforseen obstacles.

Unlike other members of crews, such as captains, doctors, or cooks, navigators aren't formally introduced. Characters that are classified as navigators are rare, dispite how important they are to the ship. Currently, the most well known, and arguably the best navigator in the One Piece world is Nami.
