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.

Switchblade7

A ship with this keyword printed on its deckplate card has two moveable blades that extend from the sides of the ship to slash enemies. You may extend and retract the blades freely at any time during a move or shoot action. After this ship completes a move or shoot action, if any part of either blade has touched an enemy ship (or ships) during that action all of those ships are considered to have been rammed and may be boarded. If there are two or more enemy ships affected, the controller of this ship may choose the order in which each ship is rammed and then boarded. If the ramming occurs by the blade(s) only, this ship is not pinned.
