noun
- The point through which the vertical line of buoyancy passes when a floating vessel is tilted slightly, used to determine stability.
Usage: nautical; also spelled metacenter (U.S.)
Examples
- The ship's metacentre must be positioned above its centre of gravity to ensure stability.
- Naval architects calculate the metacentre to predict how a vessel will respond to waves.
- A low metacentre indicates that the ship may be prone to capsizing in rough seas.
- The metacentre shifts as cargo is loaded or unloaded from the vessel.
- Understanding metacentre is essential for designing seaworthy ships.
