The primary formula used to calculate the displacement of a ship is based on its physical dimensions and block coefficient. The block coefficient is a dimensionless number that describes how closely the shape of a ship resembles a rectangular block.
In our problem, the 80 m corresponds to the distance A, and so the average speed of 4 m/s (average speed in the direction straight across the river) should be substituted into the equation to determine the time. time = (80 m)/ (4 m/s) = 20 s. It requires 20 s for the boat to travel across the river.
So let’s review and see if we can make sense of displacement in terms of numbers and equations. You can calculate an object's displacement by subtracting its original position, d 0 , from its final position d f .

Calculation Shipboard stability computer programs can be used to calculate a vessel's displacement. The process of determining a vessel's displacement begins with measuring its draft. This is accomplished by means of its "draft marks".
To determine the displacement of an object, you only have to consider the change in position between the starting point and the ending point. The path followed from one point to the other does not matter.
RAO Phase Angle. Vessel Motions. The degree to which a floating vessel will move due to a passing wave is dependent upon its transfer functions ( RAO s), which are defined by its physical properties (shape, mass, buoyancy, etc.) but primarily by its metacentric height.
