Sea Monster2

A ship with this keyword printed on its deckplate card is a sea creature. At the beginning of your turn, decide if the sea monster is submerged or on the surface. If submerged, a sea monster can only move; it cannot shoot or be shot at, and it cannot dock or touch other ships. If a sea monster is on the surface, it may move or shoot like a normal ship. It may ram opposing ships (the rammed ship becomes pinned instead of the sea monster) and it may board. After winning a boarding action the sea monster may eliminate a crew or steal a treasure (if cargo space permits), but it cannot capture crew and if it takes a unique treasure that treasure is eliminated.

S-Board4

As part of a move action, this ship may initiate a boarding party against a ship up to S away from her, without having to ram. The boarded ship may not use any boarding bonuses.
