1 A parallelepiped is defined as "a solid contained
by parallelograms" and a parallelogram is defined as "a four-sided
rectilinear figure whose opposite sides are parallel". Applying this
to 2.6.7.2, the inboard face at its mid-length should be tangential
to, or otherwise touching in at least two places, the surface corresponding
to the specified transverse extent of penetration, as illustrated
in figure 2.6.7 a.
2 Side damage should not transversely penetrate
a greater distance than the extent of 0.2∇⅓ at
design waterline, except where a lesser extent is provided for in
2.6.7.2. Refer to figures 2.6.7 b and c
3 In cases of damage under 2.6.8 and 2.6.9, the
assumed shape of damage to each section should be rectangular.
