"SHIP COURSE"

Syntax:
ship course <degree of change>

Used to change the direction in which your ship is traveling. Ships always
move to the right on the SHIP MAP. Positive values indicate a turn to the
starboard (right). Negative values indicate a turn to port (left).

For example, if you wanted to turn slightly left:
ship course -15
If you wanted to turn square to the right:
ship course 90
If you wanted to completely turn the ship around:
ship course 180

Moving from the helm will stop the turn. To view the current course and the
destination course, use SHIP STATUS.
