  • What is Longitudinal Centre of Floatation(COF)

    What is Longitudinal Centre of Floatation(COF) This is at the geometric centre of the ship’s water plane area and is the point about which the ship will trim. Consider the ship where a weight is shifted longitudinally. It can be seen that the LCF is in the same position in the ship’s length as the point where the initial and final waterlines intersect. It may be helpful to think of the

    05/04/2019· Center of Floatation (LCF): When the ship floats at a particular draft, any trimming moment acting on the ship would act about a particular point on the water plane. This point is the centroid of the area of the water plane, and is called the center of the floatation.

    09/01/2010· Your quote is correct, the CF is the center of the flotation waterplane area. Another way to think of it is, you know that by Archimedes principle a floating body displaces a volume of the liquid whose weight is equal to that of the body itself. So you have a boat floating in the sea, and now imagine that you bring a weight on board that is enough to sink the boat 1 centimeter. The weight that

  • Flotation and stability ScienceDirect

    01/01/2008· For longitudinal inclinations, the stability depends upon the distance between the center of gravity and the longitudinal metacenter. In this case, the distance between the center of buoyancy and the longitudinal metacenter will be governed by the second moment of area of the water plane about a transverse axis passing through its centroid. As the position of the center of gravity is so
