To use the sample curve shown in figure 12-14 for
finding the displacement when the draft is given, locate
the value of the mean draft on the draft scale at the left.
Then proceed horizontally across the diagram to the
displacement curve. From this point proceed vertically
downward and read the displacement from the scale.
For example, if you have a mean draft of 26 feet, the
displacement found from the curve is approximately
16,300 tons.
