Scope and general instructions

This class guideline contains procedures and methods necessary for verification of all propellers of conventional design and arrangement. For propellers not recognised as conventional by the Society, e.g. surface piercing propellers, cycloidal propellers, etc. the approval will be based on special considerations.

Damage due to impact loads from objects in the water or grounding, etc. may reduce the strength of the propeller. However, this is not included in this procedure.

The risk for- and the effect from cavitation erosion are not considered. In general, cavitation that may be harmful with respect to erosion shall be avoided.
