Taylor's curvature value k can serve as such a third parameter. It 

 will be shown that it is a useful concept , but that even three parameters may 

 not be sufficient to fix the resistance properties of ship lines. 



The process of "mixing" or adding form polynomials can be extended 

 resulting in a polynomial with an increasing number of powers and arbitrary 

 coefficients. In addition, a parallel middle body can be inserted or a bulb
