"The Metacenter is the point of intersection of the vertical line passing through the center of gravity of a floating body in equilibrio, and a vertical line through the center of gravity of the fluid displaced, if the body be turned through a small angle, so that the axis takes a position inclined to the vertical. If the metacenter is above the center of gravity, the position of the body is stable; if below it, it is unstable."—(Charles Leonard-Stuart, 1911)
