Calculation of the response motions of the ship in the above sea state 

 can be complicated. However, by use of some simplifying assumptions 

 (primarily eliminating nonlinearities), the amplitude response of the 

 C1-M-A Vl in head-on heave can be arrived at with a minimum of difficulty. 

 The results are plotted in Figure B-14.
