RS:X CLASS TECHNICAL ADVICE SHEET 1 SAIL NUMBERS Following on from advice given by the IWA regarding new rules regarding the location, size and positioning of sail numbers for windsurfer classes, the RS:X Class have issued the following instructions for placement of sail numbers for all RS:X Class events. Class Rule Racing Rule C.9.2(a) National Letters and Numbers RRS Appendix G.1.3 is overridden such that the National letters and Sail number shall be black in colour and shall be applied “back to back” on an opaque white background to the sail immediately above batten 4 and as close to the leech as possible. The opaque white background shall extend a minimum of 30mm beyond the National letters and Sail numbers. RRS Appendix G.1.2(b) is overridden and the National letters and Sail numbers shall conform to the following dimensions; Minimum height – 230mm Minimum spacing between letters or numbers – 45mm Note that the above rule has been amended and approved by ISAF as of XX May 2009. RRS 77 – Identification on Sails RRS Appendix B.2.4 RRS Appendix G For clarification; 1. Sail numbers MUST be a minimum of 230mm height and minimum spacing between national letters and sail numbers MUST be 45mm. 2. Sail numbers MUST be positioned immediately above batten 4. 3. The new CR C.9.2(a) overrides the requirement for a “-­‐“ between the National letters and Sail numbers. 4. RRS Appendix G1.2(a) still applies such that the type face shall be Helvetica or such giving equal or better legibility. If you are in doubt as to the term “clearly legible” then please contact the RS:X Class with an example of the panel you wish to put on your sail. 5. The phrase, “…as close to the leech as possible…” is explained and detailed below. For further details please contact Bas Edmonds, RS:X Class Chief Measurer [email protected] 023 8060 4202 (office) basedmonds (Skype) If the opaque sail number panel is narrow enough to fit between the fourth batten and the intermediate batten above the fourth batten, then the opaque sail number panel should be placed as close to the leech as possible. For reference the opaque sail number panel should remain entirely on the mono-­‐
film sail panel. For further details please contact Bas Edmonds, RS:X Class Chief Measurer [email protected] 023 8060 4202 (office) basedmonds (Skype) If the opaque sail number panel is not able to fit between the fourth batten and the intermediate batten above the fourth batten, then the opaque sail number panel should be placed as close to the inboard end of the intermediate batten as possible. For reference the opaque sail number panel should remain entirely on the mono-­‐film sail panel.
