With the help of these results the heaving motion of the free body generated by trans- 
verse surface waves may be determined. If the radius of the orbital circle of the surface 
wave is denoted h and the heaving motion produced by the surface wave z,, the following 
equation must be satisfied: 
z OR S/n Fh (21) 
From this the heaving motion of the free body can be computed both in magnitude and phase. 
Convergence of the Method 
To prove the convergence, first four terms in the series for the potential and then five 
terms were taken into account. The difference of the results is not significant. It, therefore, 
can be expected that both the convergence and the accuracy of the method are sufficient.
