Captain Treasure Boots (2005)

Game description from the publisher:

Captain Treasure Boots is a fast-playing pirate-themed board game. Players gather treasure from islands around the board, and bring the treasure home to port. Treasures are worth points, but they also give you special abilities, so you'll have to decide how much to keep, and how much to cash in.

Of course, treasure is never safe aboard your vessel! Players can attack each other and steal treasure – and the board is home to a few "Privateers", extra pirate ships that can be controlled by anyone.
