SHIP_AGROUND

Running aground on a ship causes damage to the ship as well as causing it to
be stuck in position. To get your vessel back into the water, you must first
turn the ship to point towards the water. Do this using the SHIP COURSE
command. The ship will turn very slowly while aground.

Once the ship has fully turned, type SHIP FLOAT and eventually the ship will
become unstuck. Moving or doing anything disruptive will cause you to stop
trying to free the ship.
