Maritime Mobile Operation in International Waters

Good amateur practice and strict rule compliance have always characterized the operations of the vast majority of US amateurs operating within the US and in international waters. The FCC has even commended the amateur community for its self-policing abilities and for adherence not only to the rules, but also to unwritten ethics dictating high standards of conduct.

From time to time, problems do crop up, and these usually stem from misinterpretations of the rules or from myths surrounding the so-called "gray areas" in the rules. Nowhere is this more true than in the case of amateur maritime mobile operation in and around foreign ports. Even hams with good intentions often have trouble in determining just what they are supposed to do when in international waters, e.g., the high seas.

On the darker side, while certainly not characteristic of most amateur maritime operators, unscrupulous yachters have been known to operate on the ham frequencies without a license. They often are of the mistaken opinion that, because they are on the high seas, the rules somehow don't apply to them. These unlicensed operators often do not install maritime mobile emergency communications gear, relying instead on a ham transceiver for all communication. This disregard of the rules and of domestic law can, among other things, complicate US and foreign efforts to reach third party traffic and other such agreements.

  • What is the definition of international waters or the "high seas?"-

    Article 1 of the Geneva Convention of 1958 on the "high seas" states: "The term 'high seas' means all parts of the sea that are not included in the territorial sea or in the internal waters of a state." Article 2 states: "The high seas being open to all nations, no state may validly purport to subject any part of them to its sovereignty." The sovereignty of a state extends to the airspace above the territorial sea as well as to the sea floor and the subsoil beneath it.
