3. (a) The intact stability characteristics of any ship carrying bulk grain should be shown to meet, throughout the voyage, at least the following criteria after taking into account in the manner described in Schedule I, the heeling moments due to grain Shift:
(i)The angle of heel due to the shift of grain should be not greater than 12 degrees;(ii)in the statical stability diagram, the net or residual area between the heeling arm curve and the righting arm curve up to the angle of heel of maximum difference between the ordinates of the two curves, or 40 degrees or the angle of flooding.* whichever is the least, should in all conditions of loading, be not less than 0.075 metreradians; and(iii)the initial metacentric height, after correction for the free surface effects of liquids in tanks, should be not less than 0.30 metres.Longitudinal divisions and saucers :
