12. A propulsion control system on a marine vessel, the propulsion control system comprising:
at least one propulsion device configured to propel the marine vessel;
a control system configured to:
based on a lock control instruction designating two locked axes and one unlocked axis out of a surge axis, a sway axis, and a yaw axis, define a movement track for the unlocked axis based on a current GPS position and a current heading, wherein the movement track is defined such that the marine vessel position with respect to each of the two locked axes is unchanged; and
control at least one propulsion device to move the marine vessel on the movement track based on a thrust command input while automatically maintaining vessel position with respect to each of the two locked axes.
