Ghost Ship6

At the beginning of each of your turns, you may decide if this ship is 'ghostly' or not. A ghostly ship ignores islands, terrain, and other ships when moving, but cannot end a move action with any part physically overlapping an island or another ship. A ghostly ship cannot ram or be rammed, pin or be pinned, board or be boarded, and cannot dock, but it may shoot and be shot at normally. A ghostly ship does not block lines of fire for other ships.

If you choose to measure from the stern, pick up the ship and rotate it (exactly) 180° so that its bow is located where its stern previously was. You may then measure movement normally from the bow’s new location.
