This book analyzes the regime of navigation in historical relation to the United Nations Convention of the Law of Sea (UNCLOS) of 10 December 1982, and then analyzes in detail the concept of international straits to arrive at a complete definition. This work examines the eight categories of straits laid out in the UNCLOS. It analyzes the right of innocent passage and the regime of transit passage, both systems of navigation in international straits, and then presents the domestic legislation and the traffic separation schemes which apply to international straits. Finally, the work includes a complete catalogue of straits with the reference to their respective UNCLOS articles.

Zusammenfassung
The four 1958 Geneva Conventions on the Law of the Sea, which codi?ed and progressively developed this sector of our legislation, were rather ephemeral despite the fact that they were constituent Conventions. In fact, the 1982 United Nations Convention on the Law of the Sea (UNCLOS) again undertook the same task with the same spirit 20 years later after a long drawn out global negotiation process in which all the marine areas and problems pending were analysed and discussed by the countries attending, and an apparently strengthened majority was attained, including the essential agreement between the principal naval powers and the third world countries, symbolised most grossly in the recognition of exclusive economic areas which were 200 miles wide in exchange for a signi?cant alteration to the legal rules applicable to the international straits. From 1973 to 1982, the negotiations showed that there were a number of particular factors affecting the seas: strait countries, user countries, long range ?shing countries, embedded countries, archipelagic countries, broad platform countries, etc. In 1982 when the UNCLOS was adopted, it seemed to be a text with justi?ed pretensions to be in force for a long period of time as the nine years of negotiations required for its adoption had taken into account the main problems pending agreement although not absolutely all.
