This document defines the loads and specifies the scantlings of sailing craft appendages on monohull sailing craft with a length of hull (L_H) measured in accordance with ISO 8666 or a load line length (see ISO 12215-5:2019, Clause 1, NOTE 1) of up to 24 m. It gives:

• design stresses;
• the structural components to be assessed;
• load cases and design loads for keel, centreboard and their attachments;
• computational methods and modelling guidance;
• the means for compliance with its provisions.
