The variety of floating bodies within this module allows the determination of the metacentre (A midway point between a ship's centre of buoyancy when upright and its centre of buoyancy when tilted). This standalone module contains 3 separate water tanks into which the 3 models supplied can be floated and tested individually but also simultaneously. The tanks and hulls are transparent to aid observation.
The model boat hulls are supplied with a flat bottom, curved and triangular form. A central mast is supplied which supports a movable sliding weight. The central mast has a scale engraved on its surface to allow quick and accurate measurement of the weights position and adjustment of the centre of gravity.
The angle of heel of each hull is read from an integral digital inclinometer. The horizontal jockey weight is mounted on a threaded shaft which equates one turn of the weight to one millimetre of movement. The weight is marked accordingly to allow ease of measurement. All three measurement devices therefore allow very accurate results to be obtained in a short time span.
