WHAT IS THE ERS

The Equipment Rules of Sailing consists of three parts

bull Part 1 ndash Use of Equipment(Section A ndash During an Event amp Section B ndash While Racing)

bull Part 2 ndash Equipment definitions (Sections C through G) Definitions of equipment and measurements for use in class rules and other rules and regulations

bull Part 3 ndash Rules governing equipment control equipment certification and inspection (Section H)

bull Appendix 1 - Racing Rules that govern the use of equipment

8

Terminology

A term used in its defined sense is printed

bull in ldquoboldrdquo type if defined in the ERS and bull in ldquoitalicrdquo type if defined in the RRS

Other words and terms are used in the sense ordinarily understood in nautical or general use in English

APPLICABILITY

The ERS may be made applicable by

otherwise have all battens removedd) have pockets of any type flattened

oute) have just sufficient tension applied to

remove wrinkles across the line of the measurement being taken

f) have only one measurement taken at a time and

g) be weighed with all attachments

Attachments at a sail edge other than a bolt rope and tabling shall be excluded when measuring

the side relevant for the measurement

bull Fittings local curvature and local cut away shall be ignored whenmeasuring a spar or dimensions taken to a spar

bull The boat shall be dry and in compliance with the class rules

57

H5 SAIL MEASUREMENTH51 Condition of the Sail

For measurement the sail shall

a) be dryb) not be attached to spars or riggingc) unless the class rules prescribe

otherwise have all battens removedd) have pockets of any type flattened

oute) have just sufficient tension applied to

remove wrinkles across the line of the measurement being taken

f) have only one measurement taken at a time and

g) be weighed with all attachments

Attachments at a sail edge other than a bolt rope and tabling shall be excluded when measuring
