Scorpion4

A ship with this keyword printed on its deckplate has a moveable blade that can slash its enemies. After a scorpion ship has completed a move action or a shoot action, if it has not rammed an opposing ship this turn it may attack any (one) opposing ship that it can touch with its blade, as a free action. The attack automatically succeeds and eliminates one mast from the target (no die roll is required, and no ability can prevent it). The target is now pinned and can be boarded (sea creatures can be pinned but not boarded); the scorpion ship is not pinned. The blade functions even if this ship is derelict.
