For sinusoidal blade motion the restriction on the Ursell number was to eliminate the influence of secondary waves; the cnoidal wave data were collected by Weggel (1976b) and are discussed in Section 2. The irregular waves used in this study included a wide range of spectral types and relative depths. Spectra were simulated by taking various theoreti- cal spectra, such as Pierson-Moskowitz, Joint North Sea Wave Project (JONSWAP), Bretschneider, and the six-parameter spectra of Ochi and Hubble (1976), and slicing the spectra into 60 equal area segments with each segment represented by a sinusoidal component at the frequency of the midpoint of the segment. Each component was transformed into a piston blade motion using Biesel's equation (Biesel, 1951) at the given frequency and assuming a random-phase relation among the components. The time histories of the 60 components were 15
