    Study Notes

    Metacentric Height

    • Metacentric height is a measure of a vessel's initial stability, representing the distance between the center of gravity and the metacenter.
    • A larger metacentric height implies a higher stability and resistance to capsizing.
    • In passenger ships, an ideal metacentric height is considered around 1-2 meters to provide a comfortable and stable ride.

    Natural Period of Rolling

    • The metacentric height affects the natural period of rolling, with a higher metacentric height resulting in a shorter period of rolling.

    Fig. 1 Apparatus

    • The apparatus shown in Fig. 1 consists of an inclining experiment setup, used to measure the metacentric height of a vessel.
