Web29 de jan. de 2015 · 2. COEFFICIENTSOFFORM - Coefficients of form are dimensionless numbers that describe hull fineness and overall shape characteristics. The coefficients are ratios of areas or volumes for the actual hull form compared to prisms or rectangles defined by the ship’s length, breadth, and draft. - Since length and breadth on the waterline as … Hull forms are defined as follows: Block measures that define the principal dimensions. They are: • Beam or breadth (B) is the width of the hull. (ex: BWL is the maximum beam at the waterline) • Draft (d) or (T) is the vertical distance from the bottom of the keel to the waterline.
