from RULES TRANSLATION:
You travel up and down the Loire with your wheel steamer. By transporting passengers and wine barrels, you fill your cash register with Louis d'Or, the currency of the time. The more stokers you hire, the further your ship travels. The more boatswains you have, the better you can assert yourself against your rivals if you head for a mooring at the shore.
The goal of the game is, by transporting passengers and wine barrels, to acquire the most Louis d'Or.
