Introduction
From 1st March 1993 the current IYRU Sail Measurement Instructions were
replaced by the IYRU Sail Measurement Rules 1993 and the IYRU
Instructions of Sail Measurement 1993. These, together with appendices
giving recommendations, Guide for Standard Class Rules for Sails and
dimension limits, should give Class Associations, Measurers and Sailmakers
all the technical information needed to construct, measure and control
"one-design"sails.
The document's contents and the intention of each part will be as follows:
- Aims And Objectives
- IYRU Sail Measurement Rules 1993
- Part A - Bermudan Sails - Definitions
- Bermudan Sails - Measurements
- Bermudan Sails - Widths and other measurements
- Part B - Additions for Gaffsails, Lugsails and Spritsails
- Guide for Standard Class Rules for Sails
- The IYRU Instructions for Sail Measurement 1993
- Recommended Limits
It is hoped these rules will be used as a basis by as many classes as
possible. If sufficient classes use the standard then real benefits wil be
gained in construction, control and cost. Most of the recommended rules
may be used by individual classes purely by the addition of appropriate
dimensions. Where, however, the essence of a rule is not appropriate for a
particular class, then this can be changed relatively easily. For example,
if a class wished to permit woven or laminated sail material of polyester
or Kevlar but exclude carbon fibres in the mainsail, then the recommended
rule 6.2.1.2 could be changed to read "the body of the sail shall"
consist of the same ply, laminated ply throughout. The ply,
laminated ply shall be of polyester fibres, aramid fibres, polyester
film.
