Ports and trade expeditions

Maritime presence tied to a network of ports, and expeditions for the trade voyages of the era, from the Venetian mudas to the Portuguese runs to India.

The Port Range map mode over the eastern Mediterranean
The Port Range map mode: the waters Venice can patrol from its bases, from the Adriatic to Crete.

Venice, Genoa and Portugal never controlled whole seas. They held scattered ports, islands and forts along their routes, and those footholds were what made their trade work. In the base game, a fleet projects maritime presence wherever it sails, so a port network adds little.

The design ties maritime presence to coastal locations. A fleet’s impact is much smaller beyond 3 sea tiles of your own coast, and a new fleet stance multiplies it where it matters.

On top of that, a new expedition mechanic models the organised trade voyages of the period: the Venetian galleys to Alexandria, the Portuguese runs to India, the Castilian convoys, and later the Dutch and British.
