Definition
A passenger ship is a vessel whose primary or significant function is the carriage of passengers for hire or reward. In maritime and regulatory law, the term carries a specific technical meaning that determines which statutory regimes, safety requirements, and liability frameworks apply to a vessel and its operator.
In general admiralty and commercial law, a passenger ship is any seagoing vessel engaged in transporting fare-paying or otherwise carried passengers as a regular or substantial part of its operation, as distinguished from cargo vessels, fishing vessels, or private pleasure craft. The classification triggers obligations to passengers under maritime tort law, including a heightened duty of care owed by common carriers by sea.
In the context of English merchant shipping legislation — from which much of the foundational Anglo-American framework derives — the term was defined by statute to mean every description of seagoing vessel carrying one or more passengers on any voyage from any place in Her Majesty's Dominions to any place whatever, and later refined to mean every mechanically propelled ship carrying passengers to, from, or between places in the United Kingdom, with specific carve-outs such as steam ferries operating within defined local limits.

Common Language
Modern common usage (Wiktionary): A ship whose primary function is to carry passengers.
Historical common usage (Webster's 1913): Not separately defined as a compound term; the concept was understood through its components — a "passenger" being one who passes or travels, and a "ship" being a large seagoing vessel.
The common and legal meanings are largely aligned in substance, but the legal definition introduces threshold requirements and statutory exclusions that the ordinary meaning does not. Whether a vessel qualifies as a "passenger ship" for regulatory purposes can turn on the number of passengers carried, the nature of the voyage, propulsion type, or whether the operator receives compensation — distinctions invisible in everyday usage.

Recognized Forms
/SUBTYPES
The regulatory category has historically been subdivided based on voyage type and passenger load:
Emigrant ship: A passenger ship carrying a defined number of steerage or emigrant passengers on ocean voyages; historically subject to stricter conditions of carriage under separate statutory schemes.
Ferry/steam ferry: Mechanically propelled vessels operating short, fixed routes between domestic points; frequently exempted from the full passenger ship regulatory regime despite technically carrying passengers.
Cruise or excursion vessel: Engaged in pleasure voyages rather than point-to-point transport; treated as passenger ships for safety and liability purposes but subject to distinct commercial regulatory treatment in modern law.

Why It Matters in Research
The threshold question in researching any maritime passenger claim is whether the vessel at issue qualifies as a "passenger ship" under the applicable statute or treaty — because that classification determines everything downstream: the duty of care owed, the liability caps available, the applicable convention (e.g., Athens Convention relating to carriage of passengers), and which safety inspection and certification requirements attach.
Researchers working in the Law Mind corpus should be alert to two recurring traps. First, the statutory definition of passenger ship has shifted repeatedly across both English and American law. Early merchant shipping acts defined the category primarily by reference to emigrant or steerage carriage; later frameworks extended coverage to all fare-paying passengers; modern IMO conventions and the U.S. Coast Guard regulatory scheme use numeric thresholds (commonly more than twelve passengers) to distinguish passenger vessels from cargo vessels carrying incidental passengers. A source that correctly states the law as of one era may be wrong for another.
Second, American admiralty law does not simply transplant English merchant shipping definitions. The U.S. approach under the Shipping Act and Coast Guard regulations uses its own taxonomy, and cases arising under 46 U.S.C. (the general maritime and shipping title) may use "passenger vessel" rather than "passenger ship" as the operative term. Bouvier's definition, drawn from Victorian-era English statute, is a starting point for understanding the regulatory tradition but should not be read as current U.S. law.
For vessel arrest and attachment research, the classification matters because a passenger ship in active service may be entitled to immunity from arrest under admiralty rules that would not protect a cargo vessel; the interplay between vessel operation, creditor rights, and the special status of passenger-carrying vessels is addressed in the encyclopedia entry cross-referenced below.

Historical Dictionary Support
Bouvier's entry on passenger ship is drawn directly from the English Merchant Shipping Act of 1889 (52 & 53 Vict. c. 29), which defined the term for purposes of that consolidated legislation as covering every seagoing vessel carrying one or more passengers on voyages from any place in Her Majesty's Dominions. The entry then refines this to mechanically propelled ships on voyages to, from, or between UK places, with the steam ferry exemption noted.
Bouvier's treatment is useful as a baseline for understanding the English-origin framework that influenced early American admiralty and maritime scholarship, but it is limited in two respects: it reflects a single statutory moment in English law and does not capture the parallel or divergent American regulatory development. Researchers should not rely on Bouvier's definition for any post-1889 English statutory changes or for American regulatory law, which developed independently through the Bureau of Navigation, the U.S. Steamboat Inspection Service, and ultimately the modern Coast Guard framework.

Jurisdictional Note
The definition of "passenger ship" varies meaningfully between the English/international regulatory tradition and U.S. law. Under the SOLAS Convention and IMO instruments, a passenger ship carries more than twelve passengers. U.S. Coast Guard regulations follow a similar numeric threshold but use the term "passenger vessel." Researchers should confirm which definitional regime governs the transaction, incident, or statute under review.
