TABLE 3 UPSETTING MOMENTSNote: Use of correction factor in column 5.(Alternative methods of correction should be shown in Table 5)Filled compartments:(i) If "V" centres have been used in Table 2 -- no correction is needed.
(ii) If "C" centres have been used in Table 2 -- correction factor is 1.06Partly filled compartments: Correction factor of 1.12 is to be used expect --
(i) Where "V" centres of full compartment has been used in Table 2(ii) Where table or curve of heeling moments has been adjusted for this correction.

If GZ curve in the nearest typical loaded condition shown in stability booklet is of normal form and maximum GZ occures at not less than 40 deg.,or the Angle of Flooding occures at not less than 40 deg., then the completion of Table 9 is sufficient to demonstrate compliance with requirementfor residual area. If any of these conditions are not met, Table 10 is to be completed.
