Plunder - The Great Cayman Treasure Quest

Players race across the Islands to be the first to reach a dive site. The first to do so selects a 'buddy' from among the other players and they then dive on the coral reef, in the hope of recovering treasure. But...their time underwater is limited and the other players have become sharks, in hot pursuit! The winner is the first player to return to the airport with 12 doubloons. - BoardGameGeek
