This draft of Egyptian standard gives requirements on the scantlings of rudders fitted to small craft with a length of hull of up to 24 m, measured according to ISO 8666. It applies only to monohulls.
It does not give requirements on rudder characteristics required for proper steering capabilities.
It only considers pressure loads on the rudder due to craft manoeuvring. Loads on the rudder or its skeg, where fitted, induced by grounding or docking, where relevant, are out of scope and need to be considered separately.
Scantlings derived from ISO 12215-8:2009 are primarily intended to apply to recreational craft including charter craft.
Worth mentioning is that this standard adopts the technical content of ISO 12215 8:2009/Cor 1:2010
Small craft (ICS code(s): 47.080)
