Eternal2

When this ship sinks, do not remove it from the game. Instead, place it docked with no masts at your home island; its crew remain onboard but any treasure or other cargo (including equipment) that it carried is treated as if the ship sunk normally. You may repair the ship as normal at your home island. When a sea creature with this keyword is eliminated, do not remove it from the game. Instead, place it docked with no segments at your home island; it may then be given repair actions (like a normal ship) until it leaves your home island.

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.
