Maximum ship squat against block coefficient at considered speeds The graph in figure 5 shows that for ships with block coefficient over 0.800, the greater the speed the bigger the squat is. On the other side, vessels with CB equal to 0.500 have small differences in squat dimensions for considered speeds. Fig. 6.
Webw = (V-V A )/V. The value of the wake fraction coefficient depends largely on the shape of the hull, but also on the propeller location and size, and has great influence on its efficiency. For ships with one propeller, the wake fraction coefficient “w” is normally in the range of 0.20 to 0.45. Ships with a large block coefficient have a ...

WebIn naval architecture a measure of a hull's fineness. It compares the boat's actual displaced volume with that of a rectangular block of the same length, breadth, and mean depth as the immersed hull. A boat with a high block coefficient is full bodied and one with a low number is fine bodied.
