Key ideas in Maritime Law on the Open Seas
- Maritime borders are layered zones extending out from shore rather than a single hard land fence
- A nation's power over ships gradually weakens the further out into the ocean you travel
- Control transitions smoothly from total national sovereignty near shore to shared global access in the open sea
- Territorial waters reach up to 12 nautical miles from the coastal baseline
- A coastal nation has full sovereign police and legal power in territorial waters, almost identically to its land territory
- Foreign ships in this 12-mile belt must obey the coastal state's domestic laws and regulations
- Innocent passage allows foreign vessels to traverse territorial waters without prior permission as long as it is continuous and expeditious
- Conducting military weapon exercises, launching aircraft, or gathering intelligence breaks innocent passage
- Commercial fishing or intentional ocean dumping while transiting strips away innocent passage rights
- The EEZ gives the coastal state exclusive rights to natural resources like fish, oil, and seabed minerals up to 200 nautical miles out
- The EEZ preserves freedom of navigation, meaning foreign ships can sail through freely without coastal state authorization
- The High Seas lie beyond all national Exclusive Economic Zones and belong to no single country
- All nations share open freedom of navigation on the High Seas, and no state can claim sovereignty or restrict international transit there
- Vessels on the High Seas are primarily governed by the laws of their own flag nation, not a neighboring coastal state
- A nation controls what is taken out of the water in an EEZ, not who sails across the surface
- A ship on international waters operates as a floating piece of territory under its registered flag state
