Vessel Routing Measures

These data show the boundaries for select vessel routing measures in U.S. waters. These measures are part of an international ships’ routing system established by the International Maritime Organization (IMO). Routing systems are systems of predetermined routes and related measures that are “recommended for use by, and may be made mandatory for, all ships, certain categories of ships or ships carrying certain cargoes when adopted and implemented in accordance with the guidelines and criteria developed by the [IMO]” and are designed to “contribute to the safety of life at sea, safety and efficiency of navigation, or protection of the marine environment.” (Safety of Life at Sea, Chapter V, reg. 10, para. 1) Direct data download | Metadata This item is curated by the Marine Cadastre team.
