TABLE 8 - WHERE THE ANGLE OF HEEL IS CLOSE TO OR ABOVE 12?, A MORE ACCURATE ANGLE OF HEEL MAY BE ESTABLISHED BY USING GRAPHIC METHODS IN TABLE 10.

TABLE 12 - THIS METHOD FOR TANKERS GIVES THE WORST CONDITION i.e. ALL TANKS ARE ASSUMED TO BE PARTLY FILLED. THE KG OF THE CARGO IN A TANK IS TO BE ASSUMED

TO BE AT THE VOLUMETRIC CENTRE OF THE TANK WHEN CALCULATING THE KG OF THE SHIP IN TABLE 2. WHERE A TANK IS LESS THAN 50% FULL., THE ACTUAL KG OF THE GRAIN MAY BE USED PROVIDED THE UPSETTING MOMENT FOR THAT TANK IS MULTIPLIED BY 1.12.
