11.2.1.3 — Multi-hulls Regeling veiligheid zeeschepen

Multi-hulls

The curves of statical stability for seagoing conditions should meet the following criteria:

.1 the area under the righting lever curve (GZ curve) should not be less than 0.075 metre-radians up to an angle of 20° when the maximum righting lever (GZ) occurs at 20° and, not less than 0.055 metre-radians up to an angle of 30° when the maximum righting lever (GZ) occurs at 30° or above. When the maximum GZ occurs at angles between 20° and 30° the corresponding area under the GZ curve, Areq should be taken as follows:-

Areq = 0.055 + 0.002(30° -θmax) metre.radians;

where θmax is the angle of heel in degrees where the GZ curve reaches its maximum;

.2 the area under the GZ curve between the angles of heel of 30° and 40°, or between 30° and the angle of downflooding if this is less than 40°, should not be less than 0.03 metre-radians;

.3 the righting lever (GZ) should be at least 0.20 metres at an angle of heel where it reaches its maximum;

.4 the maximum GZ should occur at an angle of heel not less than 20°;

.5 after correction for free surface effects, the initial metacentric height (GM) should not be less than 0.15 metres; and

.6 if the maximum righting lever (GZ) occurs at an angle of less than 20° approval of the stability should be considered by the Administration as a special case.
