Differences between Boat and Ship
Boat vs. Ship[edit]
While the terms "boat" and "ship" are often used interchangeably in common language, there are distinct technical and traditional differences between the two.[1][2] Generally, a primary distinguishing factor is size, but operational area, construction, and purpose also play significant roles in classification.[3][4] A common maritime saying illustrates the basic size difference: "A ship can carry a boat, but a boat cannot carry a ship."[3][5]
Although no single legal or universally accepted definition exists, a ship is typically a large vessel designed for transporting cargo or passengers over long distances, particularly across open oceans.[1] Boats are generally smaller craft intended for use in more restricted waters like rivers, lakes, and coastal areas. Historically, the term "ship" often referred to a sailing vessel with at least three square-rigged masts, a definition that evolved with the advent of steam power.[3]
Comparison Table[edit]
| Category | Boat | Ship |
|---|---|---|
| Size | Generally smaller; can often be carried on a ship.[3] Some consider vessels under 100 feet in length to be boats. | Large vessel, typically weighing over 500 tons. A ship is large enough to carry smaller vessels like lifeboats. |
| Operational Area | Primarily operates in coastal or inland waters such as lakes and rivers.[1] | Designed for deep-water and open-ocean voyages, often between countries. |
| Propulsion | Can be propelled by sails, motors, or manual power (e.g., oars).[4] | Propelled by dedicated, powerful engine systems.[4] |
| Crew | Can be operated by a single person or a small crew, which is not typically permanent.[3][4] | Requires a larger, professional crew with a formal command structure, often living aboard.[3] |
| Cargo Capacity | Limited to no significant cargo capacity. | Designed to carry substantial amounts of cargo or large numbers of passengers.[1] |
| Construction | Simpler in design, often with a single deck or an open cockpit.[5] | Complex construction with multiple decks and compartments to withstand harsh sea conditions.[1][5] |
| Navigation | Simpler navigation equipment suitable for near-shore travel. | Equipped with advanced navigation and technological systems for long, independent voyages. |
Legal and Other Distinctions[edit]
Legally, there is no universally agreed-upon definition that separates a boat from a ship. The United States Code defines a "vessel" as any "watercraft or other artificial contrivance used, or capable of being used, as a means of transportation on water," which includes both boats and ships.[3] Specific regulations may define a "passenger ship" based on the number of passengers it is certified to carry, often more than twelve.
Exceptions to the general rules are common. For instance, submarines are consistently referred to as "boats" by naval personnel, a tradition stemming from early submarines being small enough to be carried aboard larger ships.[3] Large vessels on the Great Lakes are also frequently called boats. Ultimately, the distinction can depend on local custom and the specific context in which the term is used.[3]
