Where territorial waters comprise straits used for international navigation (e.g., the straits of Gibraltar, Mandeb, Hormuz, and Malacca), the navigational rights of foreign shipping are strengthened by the replacement of the regime of innocent passage by one of transit passage, which places fewer restrictions on foreign ships.
The main reason Mercator's projection became so popular was because of its navigational usefulness; in his map, straight lines represent lines of constant compass bearing.
"We're making decisions based on this direction: it's one of our navigational beacons," says Libin.

They will move slowly, at 70cm a minute, with the position of one bed determining that of the other, controlled by a range of navigational systems including radio beacons in the gallery ceiling, and a laser which sweeps the gallery floor to detect obstacles.
In addition, the navigational channel would be deepened and widened.
In the six months since the euro was launched, they have had to master navigational skills of a different kind, steering a new central bank into uncharted waters, with an unknown destination.
That co-operation extends even into space: last September India got a spacecraft to orbit around Mars, with some navigational help from NASA.
In the event of an engine failure, for instance, it could use its navigational map to locate a suitable area to put down.
Microsoft's latest operating system, its first since XP in 2001, has better security and new navigational designs.
The study lends support to the idea that male and female navigational skills were honed differently by evolution for different tasks.
