What is Coefficient of fineness of Waterplane Area?

Coefficient of fineness of  waterplane Area is  defined as the ratio of the ship’s water-plane area (WPA) to the area of a rectangle having the same length (L) and breadth (B) of the ship at the waterline in question.

79

Since the ship’s WPA is less in area than the rectangle formed around it, the value of CW must always be less than 1.00.
