Definition
A chartered ship is a vessel that has been hired out under a charter-party — a formal contract by which a shipowner (or disponent owner) grants use of the vessel, or space within it, to another party (the charterer) in exchange for payment (freight). The term functions as a status label: a ship becomes a chartered ship the moment it is the subject of a valid charter-party, and it retains that status for the duration of the charter's operation.
The definition embraces several distinct commercial arrangements. A voyage charter makes the ship available for a specific voyage or series of voyages, with the owner retaining operational control. A time charter hires the vessel for a fixed period, again with the owner supplying crew and managing the ship. A bareboat or demise charter transfers possession and full operational control to the charterer, who effectively steps into the shoes of the owner for the charter period. In all cases, the vessel qualifies as a "chartered ship." The legal consequences — who bears risk of loss, who is liable to cargo interests, who can create maritime liens against the vessel — vary dramatically depending on which type of charter governs.

Common Confusion
CHARTERED SHIP vs. CHARTER-PARTY: The charter-party is the contract; the chartered ship is the vessel that contract covers. Researchers encountering one term in a historical source should immediately look for the other. A charter-party without an identified ship is an executory agreement; a ship without a charter-party is simply a vessel available for hire.
CHARTERED SHIP vs. SHIP ON DEMISE: In loose historical usage, "chartered ship" sometimes appears where "demise charter" or "bareboat charter" is technically meant. The distinction matters enormously: under a demise charter, the charterer is treated as owner pro hac vice and assumes full liability; under a voyage or time charter, the shipowner retains that liability. Do not assume "chartered ship" signals a demise arrangement unless the underlying charter-party confirms it.
CHARTERED SHIP vs. LICENSED/FRANCHISED ENTITY: No connection. The word "chartered" in maritime law means hired under a charter-party. It has nothing to do with corporate charters, bank charters, or chartered professional designations.

Why It Matters in Research
The term itself is simple; the research complexity lives in the charter-party behind it. When a historical source references a "chartered ship," the operative legal questions — lien priority, cargo liability, who can sue in rem, whether the shipowner or charterer is the "owner" for admiralty purposes — cannot be answered without knowing the charter type. Researchers should treat "chartered ship" as a pointer term that compels examination of the underlying contract.
In older admiralty cases and treatises, the distinction between voyage, time, and demise charters was not always drawn as crisply as modern practice demands. Pre-20th century sources sometimes use "chartered ship" to describe what we would now classify specifically as a demise or bareboat arrangement. Read historical sources with that ambiguity in mind.
The chartered ship is also the natural intersection point between charter-party law and maritime lien law. Materialmen, stevedores, and cargo claimants who deal with a chartered ship face a threshold question: did they contract with the owner, a time charterer, or a demise charterer? The answer determines whether a maritime lien attaches to the vessel and whether an in rem action is available. Researchers working ship arrest problems should move immediately from this entry to the Ship Arrest and Attachment encyclopedia entry.
Jurisdictional variation in how courts classify charter arrangements — particularly whether a time charter creates sufficient owner-like authority to bind the vessel in rem — has produced divergent results in U.S. and English admiralty decisions. Sources from each jurisdiction should not be read interchangeably on this point.

Historical Dictionary Support
Both the first and second editions of Black's Law Dictionary offer identical, minimal entries: "A ship hired or freighted; a ship which is the subject-matter of a charter-party." The definition is accurate but deliberately spare, functioning as a cross-reference node rather than a substantive entry. Black's treats the real doctrine as belonging to CHARTER-PARTY, not here.
What the historical dictionaries do not supply: any distinction among charter types, any guidance on liability allocation, or any signal that the legal consequences of a chartered ship depend entirely on the species of charter involved. Researchers relying solely on these entries would miss the most practically significant dimensions of the term. The historical entries are reliable as a threshold definition but should be supplemented with treatise sources on charter-party law for any substantive research purpose.

Jurisdictional Note
U.S. admiralty law (governed by federal maritime jurisdiction) and English law have developed differently on questions of charterer liability and maritime lien attachment. American courts applying the Federal Maritime Lien Act have addressed when a charterer's authority is sufficient to bind the vessel; English courts apply different rules under the Senior Courts Act 1981. Researchers should confirm the governing jurisdiction before drawing conclusions from cases decided under either system.
