Ship captains, mates, and pilots 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.

Ship captains set the course and speed of the vessel and steer it to avoid hazards and other ships. They use equipment such as depth finders and radar to watch for hazards. They gather information from lighthouses, buoys, and lights.

Ship pilots direct large ships through bodies of water to reduce chances of accidents in areas that are congested or dangerous. They know how different levels of water and changes in the weather affect navigating that particular waterway. Ship pilots may use tugboats to lead ships, direct those on board, or steer ships themselves.

Ship captains direct the crew operate the engines and signal to other vessels. They direct those who perform maintenance or operate towing or dredging gear. Captains and mates also supervise crew members and deckhands who clean the deck and bridge.

Captains check that proper procedures and safety practices are followed. They make sure that machinery and equipment are in working order.

Ship captains, mates, and pilots keep logs and records of the ship's movements, cargo, and any problems. They may purchase supplies while ships are docked. They may talk to agents about how to meet customs regulations. They also report any illegal ship operations to authorities.
