The approximate depth of the centre of buoyancy of a ship below the waterline usually lies between 0.44 draft and 0.49 draft. A closer approximation of this depth can be obtained by using Morrish¡¯s formula, which states:
Depth of centre of buoyancy below waterline = 1/3(d/2 + V/A)
d = mean draft, V = volume of displacement, A = area of the water-plane

Last Updated on Sun, 29 Jan 2017 | Centre Flotation
In previous chapters it has been shown that a ship trims about the centre of flotation. It will now be shown that, for this reason, a ship's true mean draft is measured at the centre of flotation and may not be equal to the average of the drafts forward and aft. It only does when LCF is at average.
Consider the ship shown in Figure 25.1(a) which is floating on an even keel and whose centre of flotation is FY aft of amidships. The true mean draft is KY, which is also equal to ZF, the draft at the centre of flotation.
