    The Center of Buoyancy will move as the shape of the underwater portion of the hull body changes. From this new Wlook in tables for KM T. Thank you for sharing valuable information. As shown in the figure below, in such a condition, no righting lever is generated at any angle of the heel. Stability can be broken down into several categories, each of which are alternatively emphasized in designing and operating Navy and Coast Guard ships. Units: foot tons, Newton meters, etc.

    Calculation applies to all three body axes: x,y,z Calculating trim of a flooded vehicle: Use in-water weights of the stability is that z.The ship will thus be much easier to incline and will not tend to return so quickly to the initial position.
