🚢
tonnage
[ˈtʌnɪdʒ ]
Definition
shipping measurement
Tonnage refers to the volume or weight capacity of a ship and is often used as a measure of the ship's carrying capacity. It represents the total amount of cargo that a ship can safely transport and is typically expressed in tons. There are various types of tonnage, including gross tonnage, net tonnage, and deadweight tonnage, each capturing different aspects of a vessel's capacity. Understanding tonnage is crucial for shipping companies to assess shipping costs and cargo limits effectively.
Synonyms
capacity, cargo weight, freight capacity.
Examples of usage
- The ship reached a gross tonnage of 5,000 tons.
- Higher tonnage can lead to reduced shipping costs per unit.
- Shipbuilders often focus on maximizing tonnage for efficiency.

Interesting Facts
Maritime History
- Tonnage became a crucial measurement in shipping during the 19th century for trade regulations.
- Shipbuilders began classifying vessels by carrying capacity, impacting cargo laws and maritime safety.
- Large ships like the Titanic had specific tonnage limits, informing the design and safety protocols of ocean liners.
Economics
- Tonnage taxes are levied on ships based on their carrying capacity rather than income, impacting shipping companies' operations.
- Higher tonnage can lead to lower per-unit shipping costs, influencing trade practices across industries.
- Understanding tonnage helps in calculating logistics and supply chain efficiency, crucial for global commerce.
Science
- In physics, tonnage can relate to buoyancy principles, where heavier ships require careful design to remain afloat.
- Engine power and fuel consumption are often calculated based on a vessel's tonnage for efficiency in maritime travel.
- Meteorologists may consider tonnage in studies on how much cargo affects the ship's ability to navigate through storms.
Cultural References
- Many sea shanties and songs celebrate the life of sailors and the tonnage of ships they crewed, reflecting maritime culture.
- In literature, large ships with great tonnage often symbolize adventure and exploration in works by authors like Jules Verne.
- Movies depicting naval battles often highlight ships' tonnage to emphasize their power and size in confrontations.
Origin of 'tonnage'
Main points about word origin
- The word originates from the Old French term 'tonne,' meaning a large barrel for transporting wine.
- Historically, the measurement referred to the volume a barrel could hold rather than just weight.
- The suffix '-age' indicates quantity or relatedness, which highlights that tonnage relates to a collection of weights.
The term 'tonnage' has its roots in the Middle English word 'ton' which means a large cask or container used for holding liquids. It is derived from the Old French word 'tonne', which also means a cask, and can be traced back to the Latin word 'tonna', meaning a barrel or cask. Historically, this term was used to quantify the volume of liquid a cask could hold, which later evolved to refer not just to liquid capacity but also to cargo capacity in maritime contexts. In the age of exploration and trade, ships were assessed based on their tonnage to determine how much cargo they could carry, and this has remained essential in shipping regulations and economics.
