Coefficients of Form – Ship’s Waterplane, Block, Midship and Prismatic Coefficient

Ship's Waterplane, Block, Midship and Prismatic Coefficient

The Coefficient of Form shows the relationship between the actual form of the ship and the dimensions of the ship.Waterplane Area Coefficient (Cw) It is the ratio of the actual area of the waterplane to the product of the length and breadth of the ship. As seen below, the area of the ship’s waterplane is shown shaded and a rectangle having the same length and breadth of the ship:Coefficient of fineness (Cw) = Area of waterplane ÷ (Length x Breadth) Example: Q. Find the area of the waterplane of a ship 200 meters long, 30 meters beam, which has a coefficient of fineness of … [Read more...]
