    The point through which the resultant buoyant force acts on a submerged or floating body, equivalent to the centroid of the displaced fluid volume.

    • The centre of buoyancy must be calculated to ensure the ship's stability.
    • For a fully submerged object, the centre of buoyancy coincides with the centre of mass of the displaced fluid.
    • Engineers adjust the hull design to shift the centre of buoyancy for better balance.
