The Pirates of Davy Jones Curse game includes three terrain types: Fog Banks, Reefs, and Sargasso Sea. Each terrain type brings with it a set of attributes.
When any part of a ship touches the fog bank the whole ship must be placed on the fog bank and ships turn ends. Once in the fog bank the ship is considered lost, it cannot fire cannon, be shot at, ram, pin, be boarded or board other ships. A fog bank has the numbers 1 through 6 printed around its edges. On the ships next turn the player must roll a die and exit from the number on the side of the card that matches the roll die.
Using situation cards, I have other ideas for this terrain piece, like being able to enter a fog bank if being pursued by or being fired at by an enemy ship.
This is another terrain piece that will need to be worked into the game, with a situation card. Depending on the roll of the die the player could become entangled in the Sargasso Sea and lose her ability to move or become detangled allowing the ship to continue to make her move action.
When any part of a ship touches any part of a reef, the player must roll a die. The result is the reefs rating until the end of your turn. Compare the result of the die against the amount of masts the ship had when it was constructed. If the reef rating is lower than the number of masts, the ship loses that many masts.
If the ship sustains more damage than she has masts she is wrecked and stays on the reef as a wreck. I am not really sure I will work this terrain piece into the game, yet. Perhaps I could create a situation card for this piece.
