After one hundred years in service, the Panama Canal is still one of the most important and impressive engineering achievements in modern times. Built in 1914, the Canal's opening hull designs were influenced accordingly; ships fell into three categories, those that could travel through easily and in groups (Feeder class), massive ocean going ships too big to enter the Canal (ULCV or Ultra Large Container Vessels), and the new standard - designed to the maximum limits of the Panama Canal. These ships are called PANAMAX. In Panamax, each player manages a shipping company established in the Colon Free Trade Zone. Companies accept contracts from both US coasts, China and Europe and deliver cargo in order to make money, attract investment and pay dividends. At the same time the players accumulate their own stock investments and try to make as much money as possible in an effort to have the largest personal fortune and win the game.
