What is the helm's primary role on a vessel?

• A. To control speed
• B. To navigate
• C. To steer the ship
• D. To communicate with port authorities

Answer: (C)

Steering the vessel is the helm’s primary task. The helm controls the rudder to set and maintain the ship’s direction; the helmsman follows orders to turn the rudder and adjust heading as needed to stay on course or to execute a change in direction. Speed control and propulsion are handled separately, so adjusting how fast you go isn’t the helm’s duty. Navigation involves plotting and determining positions and courses using charts, GPS, and other instruments, not steering. Communications with port authorities are managed by other bridge functions and radios. So, the main role of the helm is to steer the ship by directing the rudder to achieve the commanded course.
