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.

WebThe dwt coefficient is not used for Passenger vessels. This is because dead-weight is not so important a criterion. Furthermore, Passenger vessels are usually specialist ‘one-off ships’ so selection of a basic ship is much more difficult. For Passenger vessels, floor area in square metres is used as a means for making comparisons. http://www.mar.ist.utl.pt/mventura/Projecto-Navios-I/EN/SD-1.3.1-Estimation%20Methods.pdf hdfs show full path
