本文件规定了以下各项的测定方法: -钻机元件上的设计载荷和设计应力；和 -钻机附件和桅杆台阶/支柱的载荷和尺寸； 在单体和多体帆船上。 它还在附件中给出了评估桅杆台阶/支柱或链板的“既定做法” 注1:如果使用设计载荷和设计应力，可以使用其他工程方法。 本文件适用于船体长度不超过24米的船舶，但也适用于载重线长度不超过24米的船舶。 注2载重线长度在OMI《1966/2005国际载重线公约》中定义，小于LH。这一长度也为24 m，是几项IMO公约的下限。 本文件得出的尺寸主要适用于休闲船，包括租船。本文件不适用于仅为职业比赛设计的赛车。 本文件仅考虑航行时施加的载荷。本文件不考虑其他情况可能导致的任何载荷。 在整个文件中，除非另有说明，尺寸以(m)为单位，面积以(m2)为单位，质量以(kg)为单位，力以(N)为单位，力矩以(Nm)为单位，应力和弹性模量以N/mm2为单位(1N/mm2=1MPa)。除非另有说明，船舶在满载准备使用状态下进行评估。

This document specifies methods for the determination of: — the design loads and design stresses on rig elements; and — the loads and scantlings of rig attachments and mast steps/pillars; on monohull and multihulls sailing craft. It also gives, in Annexes, "established practices" for the assessment of mast steps/pillars or chainplates NOTE 1 Other engineering methods can be used provided the design loads and design stresses are used. This document is applicable to craft with a hull length L_H up to 24 m but it can also be applied to craft up to 24 m load line length. NOTE 2 The load line length is defined in the OMI "International Load Lines Convention 1966/2005", it is smaller than L_H. This length also sets up, at 24 m, the lower limit of several IMO conventions. Scantlings derived from this document are primarily intended to apply to recreational craft, including charter vessels. This document is not applicable to racing craft designed only for professional racing. This document only considers the loads exerted when sailing. Any loads that may result from other situations are not considered in this document. Throughout this document, and unless otherwise specified, dimensions are in (m), areas in (m²), masses in (kg), forces in (N), moments in (N m), stresses and elastic modulus in N/mm² (1 N / mm² = 1 Mpa). Unless otherwise stated, the craft is assessed in fully loaded ready for use condition.
