the added mass of sway, and hc1z0.3 and hc2z1.0 are for the damping coefficient of
sway, while in Fig. 5, the corresponding hc1 and hc2 become smaller because of the change
of d1/h1in Fig. 5. To illustrate the effects of the draft ratio d1/h1 and the width ratio h1/a on
hc1 and hc2, some results are presented in Figs. 5 and 6.
