According to Wikipedia, the term territorial waters is sometimes used informally to refer to any area of water over which a state has jurisdiction. In a narrower sense, the term is used as a synonym for the territorial sea and that is the definition used in the MSP Challenge.
Territorial sea, as defined by the 1982 United Nations Convention on the Law of the Sea,[2] are the coastal waters extending at most 12 nautical miles (22 km; 14 mi) from the baseline (usually the mean low-water mark) of a coastal state. The territorial sea is regarded as the sovereign territory of the state, although foreign ships (military and civilian) are allowed innocent passage through it, or transit passage for straits; this sovereignty also extends to the airspace over and seabed below. Adjustment of these boundaries is called, in international law, maritime delimitation.

Within the MSP Challenge Game the territorial waters do not have a special role and are not editable.

The layer was clipped to the extend of the North Sea, (as defined by IHO, retrieved on 2017-05-22). The geometry errors and duplicates were fixed; and the geometry was simplified to implement the layer in the MSP Challenge. The data layer was also reprojected to Lambert's Azimuthal Equal Area (EPSG:3035) projection.

The layer from Flanders Marine Institute (2016) was clipped to the extend of the Baltic Sea and Kattegat, (as defined by IHO, retrieved on 2017-05-22). Geometry errors and duplicates were fixed, and the geometry was simplified to implement the layer in the MSP Challenge. The data layer was also reprojected to Lambert's Azimuthal Equal Area (EPSG:3035) projection.
The layer was updated later on 2020-11-30 using the new version of HELCOM from November 2019.
Not Applicable.
There are no territorial waters defined in the Clyde Marine Region.
