The advanced metacenter can be varied to produce stable and unstable equilibrium. The equipment consists of a plastic rectangular floating pontoon, the center of gravity of which can be varied by an adjustable weight, which slides and can be clamped in any position on a vertical mast.
A single plumb bob is suspended from the mast, which indicates the angle of heel on a calibrated scale. A weight with lateral adjustment enables the degree of heel to be varied and hence the stability of the pontoon determined.
The equipment does not require a separate water tank as it may be used on the hydraulics bench by filling the volumetric tank.
