Method and system for controlling rotatable device on marine vessel

A control system of a marine vessel, the system comprising:

• a vessel control unit that controls a rotational position of at least one propulsion device that propels a marine vessel toward a heading;
• a head-mounted display in data communication with the vessel control unit, the head-mounted display having:
• a sensor system that detects a facing direction based on an orientation of the head-mounted display;
• a display positioned in an operator's field of view that displays an indicator of the facing direction;
• and
• an interface element that receives input from the operator to select the facing direction;
• generates a selected facing direction based on the input;
• and
• wherein the vessel control unit adjusts the rotational position of the propulsion device based on the selected facing direction.
