Helmsman

A helmsman is a person who steers a ship and many types of boats. In the merchant marine, this is usually an able seaman. In the Marines, it is a seaman or a quartermaster.

In the series, the only known helmsman of any crew is Jesus Burgess of the Blackbeard Pirates. The Straw Hat Pirates do not have an official helmsman, though the most common person seen steering the ship is either Nami or Tony Tony Chopper in his human form. However, Franky and Sanji have been seen steering the Thousand Sunny many times. Jinbei also shows skills at steering a ship.
