Title 46 › Subtitle Subtitle VII— Security and Drug Enforcement › Chapter 705— MARITIME DRUG LAW ENFORCEMENT › § 70502
Defines key words and explains which boats count for the rules in this chapter. The definitions from section 102 of the Comprehensive Drug Abuse Prevention and Control Act of 1970 (21 U.S.C. 802) also apply. A "vessel of the United States" means three things: a boat documented under U.S. law or given a U.S. number; a boat at least partly owned by a U.S. citizen, the U.S. government, a state government, or a U.S. corporation unless the boat has been given foreign nationality and the master claims that foreign nationality when a U.S. officer acts; and a boat that used to be U.S.-documented but was illegally sold to a non‑U.S. person or put under foreign registry. A "vessel subject to the jurisdiction of the United States" covers stateless boats, boats treated like stateless under the 1958 High Seas Convention, foreign-registered boats when that foreign country agrees to U.S. enforcement, boats in U.S. customs waters, boats in a foreign nation’s territorial waters if that nation agrees, and boats in the U.S. contiguous zone (per Presidential Proclamation 7219 of September 2, 1999) if they are entering, leaving, or are "hovering" as defined in the Tariff Act. Foreign consent may be given by radio, phone, or electronic means and is proven by a certification from the Secretary of State. A "vessel without nationality" covers cases where a claimed registry is denied, not claimed when asked, not affirmed by the claimed nation, or no one claims to be master. A claim of nationality can be shown by having documents on board, flying the flag, or a verbal claim by the master. A "semi-submersible vessel" is mostly under water but not fully; a "submersible vessel" can operate completely below the surface.
