For all of these scenarios, unless specifically stated, I use my victory conditions listed under 'Winning the Game' on the rules page.

GODZILLA - Godzilla protects the island with all of the treasure. Each side of the island is numbered and any ship wishing to dock at the island will need to roll the die. If they roll the number that they are docked at then Godzilla eats the ship and it sinks. Any other roll and Godzilla has accepted them and they may dock freely. Godzilla has a short memory though so ships must roll to see if they get eaten each time they dock. Forts may not be built on this island.

BERMUDA TRIANGLE - Ships in the Bermuda Triangle must roll a die. A roll of 5 or 6 means they are caught in the triangle until their next turn. Any other roll and they continue as normal. Upon next turn they roll again. A roll of 1 means they are still trapped. Any other roll means they exit the triangle in a specific direction and travel 4 L in a straight line. One point is labeled 2 or 3, another is labeled 4 or 5 and the third is labeled 6. The ship exits at the point that they rolled and travels in that direction the 4 L. Running into an island docks the ship at that island.

VOLCANO - Each player after their turn rolls the die, on a roll of a 6 the volcano erupts. Each ship within S of the island loses 2 masts. Each ship within L of the island loses 1 mast. Ships docked at the island are destroyed. Forts on the island (should someone be foolish enough to put on there) are destroyed. I give credit to Cke1st for this scenario as he has a very similar volcano scenario that I based it on.

COLONISTS - Both home islands are located within L of each other and are filled with colonists. Infantry from the board game RISK work well for this. Ships load colonists as they would cargo and take the colonists to the new world, which is another island much farther away. The 'new world' island contains all of the treasure. Once docked at this island ships unload their colonists and take random treasure pieces in equal quantity to the number of colonists that were dropped off. Ships that are sunk while carrying colonists results in the deaths of the colonists. The game is over when all treasure is collected from the island. The amount of treasure at the start of the game should be less than the total number of colonists. The winning player is the one with the most treasure.

SHIPYARDS - Game is played with an agreed upon number of Total Fleet  points (example 80 pts) and a smaller Starting Fleet point total (example 40 points). Players can use treasure gathered from wild islands to buy more ships at their home island. In this scenario the value of treasure pieces has no bearing on winning the game. The game is played for an agreed upon period of time and the point value of remaining ships in play is totaled to determine the victor. Alternatively can be played as a deathmatch game.
