What is defined as the weight of the boat excluding fuel, water, cargo, crew, and passengers?

The term that describes the weight of the boat excluding fuel, water, cargo, crew, and passengers is known as light displacement. This measurement provides a baseline weight of the vessel, allowing for a clear understanding of its structural weight without added elements. It captures the weight of the boat itself along with its internal systems and fixtures but not any variable loads such as fuel or passengers that can change over time.

This specific definition is important in various maritime contexts, including stability calculations and assessment of performance, as it helps distinguish the vessel's inherent mass from additional weight that could influence handling and buoyancy. Understanding light displacement is essential for boat crew members when loading and unloading to ensure safe operation.
