Ship captains and mates direct and navigate all kinds of ships.
Captains or masters are in command of ships. They oversee the loading and unloading of cargo or passengers. They often collect fares from passengers, or direct others to do so.

Ship captains direct the crew who steer the ship, operate the engines, and signal to other vessels. They direct those who perform maintenance or operate towing or dredging gear.
Captains check that proper procedures and safety practices are followed. They make sure that machinery and equipment are in working order. They often run safety drills with the crew.
Captains on larger ships have deck officers or mates as assistants. Merchant marine ships have multiple mates. Captains interview, hire, and instruct mates. They assign mates to watches and living quarters.
Mates oversee operation of the vessel for part of the day when the captain is off duty.
Captains keep logs and records of the ship's movements and cargo. They may purchase supplies while ships are docked. If they operate fishing vessels, captains find buyers for the fish they caught. They may talk to agents about how to meet customs regulations.
