A summary of the expressions for the various coefficients for the whole ship 

 according to the notation in Eqs. (1) and (2) is given in Table 6.

For the cross-sectional values of the coefficients similar expressions can 

 be derived from the Eqs. (5) to (12). For the comparison with the experimental 

 results two of these expressions are given here, namely:
