Seas, straits and passages

Coastal provinces open onto sea zones; armies embark, sail from zone to zone and land on another coast. Short straits (Gibraltar, Messina, the Bosporus…) link land directly.

Passages

Some sea links run through a canal or a narrow strait – Suez, Panama, the Turkish Straits, Øresund. Whoever controls the province on the passage can close it to enemies.

Across the Pacific

On the world map the ocean wraps across the map's edge: a fleet sailing west from Japan comes out off California.
