Deadweight, in the context of shipping, refers to the maximum weight a vessel can safely carry when fully loaded. This includes the weight of cargo, crew, supplies, and fuel, known as bunkers. The deadweight is determined by measuring the weight of the water displaced by the vessel when it is loaded compared to when it is empty. The vessel must remain within safe limits, indicated by the Plimsoll line, to ensure stability and safety at sea.

Legal Use & context
The term "deadweight" is primarily used in maritime law and shipping regulations. It plays a crucial role in determining vessel capacity and compliance with safety standards. Legal professionals may encounter this term when dealing with shipping contracts, insurance policies, and maritime disputes. Understanding deadweight is essential for those involved in the shipping industry, including shipowners, charterers, and maritime lawyers.

Key legal elements
Real-world examples
Here are a couple of examples of abatement:
Example 1: A cargo ship has a deadweight of 50,000 tons. This means it can carry a combination of cargo, crew, and fuel that does not exceed this weight. If the ship carries 30,000 tons of cargo, it can safely accommodate up to 20,000 tons of crew and bunkers.
Example 2: A vessel is found to be overloaded beyond its deadweight capacity, leading to legal action from maritime authorities for violating safety regulations. (hypothetical example)
