Definition
In law, navigating refers to the act of operating, propelling, or directing a vessel through water. The term appears most often in admiralty and maritime contexts, where its precise meaning determines the scope of maritime jurisdiction, the applicability of collision rules, and the extent of liability under maritime law.
The word functions both as a gerund (navigating as an activity) and as a present participle modifying a vessel's status at a given moment. In the admiralty context, this distinction matters: whether a vessel was navigating at the time of an incident can determine whether maritime law applies at all.
Bouvier's preserves a useful illustration: a vessel that, though touching bottom, forces her way by her own screw through soft mud is navigating. The vessel's active use of its own propulsion, even under impaired conditions, is sufficient. Mere physical contact with the waterway floor does not suspend the vessel's navigating status.
Navigating is closely coupled to the concept of navigable waters — the class of waters on which navigation is legally recognized — but the two are distinct. Waters may be navigable in law without anything actually navigating them at a given moment; and questions about what it means to be navigating arise only once the navigability of the waterway is established.

Common Language
Modern common usage (Wiktionary): Present participle and gerund of navigate — to find one's way, to steer or pilot a vessel or vehicle, or figuratively to manage a complex situation.
Historical common usage (Webster's 1913): Not independently listed; navigate is defined as sailing, passing over water in ships, or directing the course of a ship.
The common and legal senses are largely continuous for the core maritime meaning. The legal specificity lies in navigating as a term of art with jurisdictional and liability consequences — not merely a description of physical motion, but a legal status triggering admiralty rules. A vessel drifting without power, moored indefinitely, or beached may raise genuine questions about whether it is navigating in the legal sense; ordinary usage would not draw this line.

Why It Matters in Research
Researchers encounter navigating most often in two distinct contexts that require separate analytical tracks.
First, in admiralty collision law, whether a vessel was navigating at the time of an incident determines the applicability of COLREGS (the International Regulations for Preventing Collisions at Sea) and analogous inland navigation rules. The Bouvier's illustration — a vessel pushing through mud under its own power — reflects judicial willingness to construe navigating broadly for liability purposes. Researchers examining fault allocation in collision cases should treat navigating status as a threshold question before reaching the navigation rules themselves.
Second, in water law and environmental regulation, navigating (as the activity that makes waters legally navigable) connects to jurisdictional questions about federal authority over waterways. Bouvier's traces competing definitions of navigability — tidal, capable of supporting sea-going vessels, or any water usable for navigation — and the standard applied varies by jurisdiction and era. A stream's navigability has historically been determined by whether it could be navigated in fact, which means historical cases often turn on testimony about actual navigating activity on the water in question.
Trap for researchers: In older sources, navigating and navigable are often used interchangeably or in close proximity in ways that blur the act (navigating) with the legal status of the water (navigable). Careful reading of context is required to determine which sense governs.
Historical sources, including Bouvier's, do not systematically address navigating in the context of vessels other than traditional watercraft. Modern admiralty practice has extended the analysis to unusual craft; historical dictionary entries will not be reliable guides for those questions.

Historical Dictionary Support
Bouvier's Law Dictionary addresses navigating only incidentally, embedded within extended discussions of navigable waters and the tests for navigability. The entry provides the mud-bottom illustration as a practical limit case — courts were asked whether a vessel struggling through soft mud under its own screw retained navigating status, and the answer was yes. This reflects the functional, activity-based approach of admiralty law: legal status follows actual operation, not ideal conditions.
Bouvier's also synthesizes the competing tests for navigability across American jurisdictions — tidal reach, capacity for sea-going vessels, and general usability for navigation — noting North Carolina's adoption of the sea-going vessel standard rather than the tidal test. These variations matter because the legal significance of navigating activity depends entirely on whether the underlying water qualifies as navigable under the applicable standard.
What Bouvier's does not address: the regulatory dimension of navigating under federal environmental statutes, the treatment of recreational or non-commercial vessels, and the full development of the federal navigational servitude. Researchers working in those areas will need to move beyond historical dictionary sources.

Jurisdictional Note
The standard for what waters support legally cognizable navigation varies by jurisdiction and era. Federal law applies a commerce-based navigability test; state law tests have historically diverged, with some states (including North Carolina as noted in Bouvier's) applying a vessel-capacity standard rather than a tidal one. Whether an act of navigating on a given body of water triggers federal or state jurisdiction depends on which test applies.
