Dock Q: If my ship has more than one movement segment in its base move, can it move away from an island and re-dock using a single move action? Is that considered leaving? A: Yes, a ship may move away and re-dock at the same island using a single move action. If at least one segment ended with the ship in an undocked position it is considered to have left, even if it returns to the island with another segment. Q: Is docking an action? A: Docking (or being docked) is not an action, but a condition or state of being of a ship that can result from an action or the use of certain abilities. If a ships bow touches or is touching an island, it is docked. Q: If my ship docks at a wild island while carrying an explorer can I use the crew transfer rule (a free action while docked) to unload my other crew before exploring the island? A: No, the remainder of the ships move action (including use of the Explorer) must be completed before you may transfer crew to or from the island as a free action.
