Distribution of Hydrodynamic Forces on a Shipmodel 



Lpp/7 



and so on. Assuming that the distributions of the cross- sectional values of the 

 coefficients a', b' , etc., are continuous curves, these distributions can be de- 

 termined from the seven mean cross-section values. In the Figs. 7, 8, 9 and 10 

 the distributions of the added mass a, the damping coefficient b and the cross- 

 coupling coefficients d and e are given as a function of speed and frequency. 

 Numerical values of the section results, a*, b* , etc., are summarized in the 

 Tables 2, 3, 4 and 5.
