Fear6

For each enemy ship within S of this ship at the beginning of this ship's turn, roll a d6. On a result of 5, none of the target's ship or crew abilities can be used that turn. On a 6, the target's base move is reduced to S on her next turn.

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.
