Comparative evaluations were conducted using a Lamboley pendulum test to determine the radius of gyration in the pitch axis and to locate the centre of gravity of the East Coast 12-metre (EC- 12M) model sail yachts. The Lamboley simultaneous equations were solved using a computer programmed for this purpose. From this data, the righting moment at 20 deg heel and the moment of inertia in the pitch axis, without the rig, were calculated and plotted. Critical pitching frequencies were calculated, assuming a nominal mast and rig; and critical wavelengths were calculated and plotted versus boat speed.
