This standard applies to sailing yachts of L > 24 m.

Scope of this standard is the structural integrity of one- or multiple-masted, Bermudian rigged monohull or multihull sailing yachts with spars made of carbon fibre reinforced plastics (CRP) or aluminium alloy; including the dimensioning of standing rigging, mast and boom sections as well as local construction in way of fittings structurally attached to the spars.

For other rigged sailing yachts, the principles presented in the following shall be used as a general guidance. Any detailed analysis which is leading to different reserve or reduction factors can be submitted on the basis of an equivalent safety.

Upon request, the performance on construction can be supervised by DNV. Basis for this is a relevant shop approval for the typical construction techniques. The survey will be carried out in periodical intervals where an assessment is made whether the product under supervision is built in accordance with approved documentation and the societies standards by random control.
