Block Coefficient
Fig. 3.4. Deadweight/displacement ratio versus block coefficient.
When a single Kd value for a particular ship type is known the trend of the lines
on Fig. 3.3 can be used to correct this to a different deadweight.
Although the correlation between deadweighddisplacement ratio and block
coefficient shown in Fig. 3.4 is interesting, it is unfortunately not of any practical
use to a designer as Cb is still an unknown quantity when a designer is trying to
decide on an appropriate deadweight/displacement ratio.
