3.2.1 The angle of heel due to steady wind when
the heeling lever HL1, obtained as in 1.3, is applied to
the intact stability curve should not exceed 16°.
3.2.2 The angle of heel due to steady wind when
the heeling lever HL3, obtained as in 2.2, is applied to
the residual stability curve after damage, should not exceed 20°.
