The term 'SHIP HANDLER' can be broken down into two words: 'SHIP' and 'HANDLER'. A HELMSMAN is someone who is responsible for steering a SHIP, usually by using a wheel or tiller. They are also responsible for monitoring the SHIP's speed and direction. They must be able to read navigational charts and use navigational instruments to ensure the SHIP is on course. They must also be able to communicate with other crew members and the captain to ensure the SHIP is operating safely.
