This part of ISO 12215 gives requirements on the scantlings of rudders fitted to small craft with a length of hull, LH, of up to 24 m, measured according to ISO 8666. It applies only to monohulls. NOTE 1 ISO 12215-7 defines the loads for multihull rudders. This part of ISO 12215 is then used for rudder scantlings determination. This part of ISO 12215 does not give requirements on rudder characteristics required for proper steering capabilities. This part of ISO 12215 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. NOTE 2 Scantlings derived from this part of ISO 12215 are primarily intended to apply to recreational craft including charter craft.
