Block coefficient vessel

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. WebThe "block coefficient" or "coefficient of fineness" of the average freight steamer varies from 0.7 to 0.75, while the coefficient of a combination freight and passenger steamer is about 0.65; that of a fast passenger steamer is about 0.6, while racing yachts may have a coefficient as low as 0.4.
