7.1.1 Skegs are
to be effectively integrated into the adjacent structure and their
design is to be such as to facilitate this.
7.1.2 The scantlings
of skegs are to be sufficient to withstand any docking forces that
they may be subjected to.
7.1.3 The thickness
of the skeg plating is in no case to be taken as less than 1,5 times
the thickness of the adjacent bottom shell or the fin and tuck laminate
whichever is the greater.
7.1.4 Where metallic
sub-frames are laminated into skegs, providing transverse stiffening
to the skeg and support for the rudder pintle, such stiffening members
are to be fully integrated with hull framing to ensure continuity
of strength.
7.1.5 The scantlings
of skegs of composite construction will be specially considered on
the basis of the Rules, and in this respect are to be of equivalent
strength and load carrying capability to that required for skegs of
steel construction from Pt 3, Ch 3, 3.3 Rudder horns.
Due account is to be taken of the differing material properties.
7.1.6 Direct
calculations may be used as an alternative to the requirements of Pt 4, Ch 3, 7.1 Skegs 7.1.5 to determine the scantlings of
composite skegs. Such calculations are to be submitted for appraisal.
