Meaning and Definition
A stability measurement in naval architecture and ship design representing the vertical distance between a vessel's centre of gravity and its metacenter.
A quantitative measure of a floating body's initial static stability; a larger value indicates greater resistance to initial rolling or capsizing. The term is also used metaphorically in project management or systems design to describe a measure of inherent stability or resilience to perturbations.

Differences
No significant lexical differences. Spelling follows national conventions for related terms (e.g., 'centre' vs. 'center' of gravity).
Connotations
Identical technical connotation in both varieties.
Frequency
Extremely rare outside naval engineering, marine architecture, and physics contexts in both regions.

FAQ
Frequently Asked Questions
No, the initial metacentric height (GM) is only valid for very small angles of heel (typically <7-10 degrees). For larger angles, the concept of the righting arm curve is used.
Yes, a negative metacentric height means the centre of gravity is above the metacenter, resulting in an unstable equilibrium. The vessel will capsize if heeled slightly.
It is a linear measurement, so metres (m) in SI units or feet (ft) in imperial units.
It is a fundamental, easy-to-calculate measure of a ship's inherent initial stability, directly influencing safety, comfort (rolling period), and compliance with international regulations.

Memory Aids
Mnemonic
Imagine a METronome on a CENTRAL pivot. Its HEIGHT above the base determines how stably it swings back to centre. METaCENTRic HEIGHT = stability from height.
Conceptual Metaphor
STABILITY IS VERTICAL DISTANCE; A SYSTEM'S RESILIENCE IS ITS MARGIN OF SAFETY (metaphorical extension).
