The quality of being metacentric.

Of or pertaining to a metacenter. / (genetics) Of a chromosome: having the centromere approximately in the middle, such that the two arms are of similar length.

A metacentric chromosome.

plural of metacentric

(physics, nautical) The point where a vertical line through a tilted vessel's center of buoyancy intersects the originally-vertical (but-now-tilted) line that passed through the center of buoyancy when the vessel was upright; it must be above the vessel's center of gravity for the vessel to have positive static stability (to tend to return to an upright orientation if rolled to one side, rather than to continue rolling to an inverted orientation).

plural of metacentre

metacentric

(nautical) The tendency of a ship or other water-going vessel to remain upright due to its centre of gravity being below its centre of buoyancy, ie. basically having most of its weight down low.

plural of metacentric height

(nautical, physics) The vertical distance between the metacentre and center of mass (conventionally taken to be positive when the metacentre is above the center of mass, and negative when the center of mass is above the metacentre) of a vessel (such as a ship or a boat) when the vessel is upright with zero bank angle; measures the vessel's tendency to resist being rolled from the upright orientation; must be positive in order for the vessel to have positive static stability.
