There are a few tricky areas on the map. How to move into and out of them is explained below :
Bulgaria, Spain and St Petersburg : These are the only coastal provinces that have two separately identified coasts. A fleet entering one of these provinces enters along one coast and can then move to a province adjacent to that coast only. The fleet, nevertheless, is considered to be occupying the entire province. For example, a fleet at Spain’s North coast (spanc) can only go to Gascony (gas), Portugal (por) (or Mid-Atlantic (MID)).
Kiel and Constantinople : Because of the waterways that run through these two provinces, they are considered as having one coast.. Fleets can enter them along one coast and be considered anywhere along the coastline. For example, a fleet could move from Black Sea (BLA) to Constantinople (con) on one turn and then from Constantinople to Aegean Sea (AEG). Armies can also pass into and out of these provinces, freely bridging these waterways. This does not mean that units can jump over these provinces.
Sweden and Denmark : An army or fleet can move from Sweden (swe) to Denmark (den) (or vice versa) in one turn. A fleet moving from the Baltic Sea (BAT) cannot move directly to the Skagerrak (SKA) province (or vice versa), but must first move to Sweden or Denmark. The common border with Denmark does not separate the coast of Sweden into two coastlines. Denmark does not border on Berlin (ber).
