Definition
In maritime and insurance law, "sailing" refers to the legal commencement of a vessel's voyage for the purposes of a charter party or marine insurance policy. It does not require that the vessel actually move through open water under favorable conditions. A vessel is considered to have sailed — and the voyage to have commenced — when three conditions converge: the vessel has quit her moorings, she is in complete readiness for sea, and the master holds an actual and genuine intention to proceed on the voyage. Subsequent interruption by adverse winds or weather, including a return to anchor, does not defeat the sailing if the intent to proceed remains. The legal moment of sailing is thus a matter of readiness and intent, not uninterrupted physical progress.
Common Language
Modern common usage (Wiktionary): Motion across a body of water in a craft powered by wind, as a sport or leisure activity; also, the time of departure from a port or a scheduled voyage by a ferry or ship.
Historical common usage (Webster's 1913): The act of a vessel moving on water impelled by wind or steam; the act of starting on a voyage; also the art of managing a vessel, including seamanship and navigation.
The common meaning treats sailing as either a physical activity (moving under wind power) or a scheduled departure time. The legal meaning is narrower and more technical: it fixes a precise moment in time for contractual and insurance purposes, and that moment can occur even when no physical movement through the water has yet taken place. The gap matters because a vessel can be legally "sailing" on a voyage while still at anchor.
Common Confusion
"Sailing" in the insurance and charter party context is sometimes conflated with departure or with the inception of risk under a voyage policy. These are related but distinct. Risk under a voyage policy may attach at different points depending on policy language, while "sailing" as defined here is a doctrinal standard for determining when a voyage has commenced. A vessel may be covered under a policy before she has legally "sailed," and the sailing determination governs specific contractual obligations (such as warranty compliance) independently of when the insurer's risk begins.
Why It Matters in Research
This term appears almost exclusively in the context of 19th- and early 20th-century maritime insurance disputes and charter party construction, where the precise moment of voyage commencement had direct consequences for warranty compliance, risk attachment, and policy coverage. Researchers working in these areas should note:
The standard drawn from Bowen v. Hope Insurance Co. — complete readiness plus genuine intent — was the dominant common law benchmark and appears consistently across historical sources. When reading historical policies or charter party forms, "the sailing" or "from the sailing" should be interpreted against this standard, not against modern colloquial usage.
The Bouvier formulation is slightly softer than Black's, emphasizing "intention of proceeding at once" rather than the master's actual and real intention, which can matter when reconstructing argumentation in older cases. The distinction is subtle but worth flagging when analyzing historical pleadings or judicial opinions that cite competing authorities.
Jurisdictional note: Federal admiralty courts dominated this doctrine, so state variations are less significant here than in most areas, but state insurance law occasionally applied its own commencement rules when admiralty jurisdiction was not invoked.
Researchers should also be alert to the fact that modern shipping law has largely displaced this common law standard through statutory regimes (such as the Carriage of Goods by Sea Act) and standard form contract provisions that define voyage commencement explicitly. The historical "sailing" doctrine is rarely litigated today but remains essential for reading 19th-century case law and policy language.
Historical Dictionary Support
All three source dictionaries converge on the same doctrinal core: legal sailing requires readiness for sea plus intent to proceed, and physical obstruction by weather does not negate a sailing already commenced. The agreement across Black's first and second editions and Bouvier is unusually tight, reflecting the settled nature of this point in the period when these dictionaries were compiled.
Black's 1st and 2nd editions both trace the principle to Bowen v. Hope Insurance Co., 20 Pick. (Mass.) 278, making this one of the few instances where a Massachusetts state court decision anchored a doctrine that was otherwise predominantly federal in application. Bouvier cites the same case (at page 275 of the same volume, likely a pinpoint variation) and frames the issue as one of "construction" — emphasizing the interpretive purpose the term serves in both charter party and insurance contexts.
What the historical dictionaries do not address: they say nothing about the vessel's papers, cargo loading, crew complement, or clearance formalities as elements of "readiness," leaving those factual questions to case-by-case analysis. They also do not address the commencement of a return voyage, a port-to-port leg within a larger voyage, or time charters — contexts where a different analysis may apply.
Jurisdictional Note
The doctrine is primarily a product of federal admiralty jurisdiction and Massachusetts common law (via Bowen v. Hope). English admiralty decisions were also influential in shaping the standard during the 19th century, and researchers working with pre-1900 American materials should expect to encounter English precedent cited alongside American cases without clear distinction.
