What does metacentre mean?
The metacentre is a critical concept in naval architecture and engineering, referring to the point where a vertical line through the centre of buoyancy intersects the line of symmetry of a floating object. This point is essential in calculating the stability of a vessel or floating structure, determining its ability to withstand external forces such as wind or waves. The metacentre is a key factor in designing and constructing stable and safe boats, ships, and other floating objects. Understanding the metacentre is crucial for ensuring the safety and performance of these vessels in various conditions.

Etymology of metacentre
The term 'metacentre' originates from the Greek words 'meta', meaning 'beyond' or 'transcending', and 'centre', referring to a central point. The concept of metacentre has its roots in the study of buoyancy and stability, dating back to the work of 18th-century scientists and engineers who sought to understand the behaviour of floating objects.
