Small craft — Hull construction and scantlings — Part 9: Sailing craft appendages

ISO 12215-9:2011 defines the loads and specifies the scantlings of sailing craft appendages on monohull sailing craft with a length of hull of up to 24 m, measured according to ISO 8666. 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, and the means for compliance with its provisions.

Petits navires — Construction de coques et échantillons — Partie 9: Appendices des bateaux à voiles

L'ISO 12215-9:2011 définit les chargements et spécifie l'échantillonnage des appendices des bateaux à voiles d'une longueur de coque, LH, mesurée conformément à l'ISO 8666, inférieure ou égale à 24 m. Elle fournit: les contraintes de conception, les éléments structurels à évaluer, les cas de chargement et les charges de conception pour la quille, la dérive et leurs éléments de liaison, les méthodes de calcul et des instructions de modélisation et les moyens de se conformer à ses dispositions.

Introduction
This document recognizes the importance of adequate scantlings, construction practice and condition
assessment for sailing craft appendages, principally the ballast keel.
The loss of a ballast keel leading to craft capsize is one of the major casualty hazards on sailing craft and
therefore the structural effectiveness of all elements of the keel and its connection to the craft is paramount.
This document specifies the design loads and their associated stress factors. The user (e.g. the designer or
builder) then has a choice of one of the following two options to assess the structural arrangement:
a) Use of computational methods which allow the structure to be modelled three-dimensionally. Methods
include finite element analysis, matrix displacement or framework methods, following which Annex A is
completed for compliance. General guidance is provided on modelling assumptions in Clause 8.
b) Use of simplified two-dimensional stress formulae. These are presented in Annexes B to F and, if this
option is chosen, use of all applicable annexes will be necessary to fulfil the requirements of this
document, following which Annex A is completed for compliance.
This document has been developed in consideration of current practice and sound engineering principles. The
design loads and criteria of this document may be used with the scantling determination formulae of this
document or using equivalent engineering methods as indicated in a) above.
This document reflects current practice, provided the craft is correctly handled in accordance with good
seamanship, is well designed and built, maintained, equipped and operated at a speed appropriate to the
prevailing sea state. Inspection of all appendages after grounding is essential.
NOTE Compliance with this document will not ensure a satisfactory design in all cases nor absolve the user, such as
the designer or builder, of their design responsibilities, with whom such responsibilities are entirely vested.
Racing craft are not the principal focus of the ISO 12215 series. In particular, users are strongly cautioned
against attempting to design scantlings for racing craft such that scantlings only just comply.

Part 9:
Sailing craft appendages
1 Scope
This document defines the loads and specifies the scantlings of sailing craft appendages on monohull sailing
craft with a length of hull (LH) 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.
Table 4 lists where the structural components to be assessed are found in this document and describes
thestep-by-step procedures to establish compliance, step by step.
