Web8 de abr. de 2024 · The metacentre is the place where all the lines of the upward buoyancy force of φ ± dφ intersect (at angle φ). Whenever the ship becomes vertical, the metacentre is well above the centre of gravity, causing the ship to roll in the reverse direction of the heel. GM is another abbreviation for this distance. WebPrismatic Coefficient. The longitudinal prismatic coefficient, CP, or simply prismatic coefficient is the ratio of the volume of displacement to the volume of a prism having a length equal to the length between perpendiculars and a cross-sectional area equal to the midship sectional area.
