Bombardier3

A ship with this keyword printed on its deckplate card has a special bombardier cannon that has a printed rank but is not associated with a mast. The special cannon cannot be eliminated, cannot be targeted by enemy effects, and cannot be assigned equipment. If the cannon roll for the special cannon is a 1 it jams and cannot be used again until the ship is given a repair action specifically to fix it. After placing ships at your home island but before the game begins, choose whether the special cannon will be an artillery cannon (use the artillery piece) or a flamestrike cannon (use the flame piece). This choice cannot be changed after the game has begun. The artillery cannon has the Extended Range keyword. The flamestrike cannon has a range of S (you may measure using the S-length flame piece); when it hits, replace one of the target's masts with a fire mast.

Submarine2

A ship with this keyword printed on its deckplate card has removable hull pieces that are treated exactly the same as masts on a normal ship. At the beginning of your turn, decide if the submarine is submerged or on the surface. If submerged, lift the submarine's hull from its base so only the 'spine' is showing (the hull is set aside, and is still used to track damage to the submarine). When the submarine is on the surface replace the hull (minus any previously eliminated hull pieces). If submerged, a submarine can only move; it cannot shoot or be shot at, it cannot repair, it cannot dock, and it cannot be rammed. A submerged submarine may ram another ship, but regardless of success it must immediately be moved S away from the target instead of boarding. If a submarine is on the surface it functions exactly like a normal ship, except that it cannot pin or be pinned, cannot tow or be towed, and is not damaged when rammed (it can still board and be boarded normally).

Iron Hull7

Two hits from the same shoot action are required to eliminate one of this ship's masts.
