2018 USSCA North American Championship – Sail Number Requirements
Posted June 14, 2018
If you will be competing in the upcoming 2018 USSCA North American Championship, or any other World Championship qualifying event, please be sure your sail numbers are compliant with our current class rule 3.6.5. To be fair for all competitors, provisions in the rule pertaining to size, shape, color and placement will be enforced. A hyperlink to the class diagram is attached here:
For sails purchased after January 1, 2015: sail numbers must comply with RRS Appendix G.1 as modified by our class rules. This means that minimum height of numbers is 300mm (11-13/16”), minimum space between numbers is 60mm (2-23/64”) and numbers must still be positioned as indicated in the class diagram centered beneath the Sunfish emblem.
For “older” sails purchased prior to January 1, 2015: numbers may comply with RRS G.1 as described above or as previously allowed in our rules prior to the latest change in January 1, 2015. This allows for “older” sails to use 10-inch numbers. Details are in our class rule 3.6.5 which should be referred to for placement, spacing and other details.
For all sails regardless of when they were purchased:
Numbers must be of the same color.
On white colored sails, numbers must be dark and dense, preferably black. Dark blue is acceptable.
On dark colored sails, numbers must be white.
Numbers must be of uniform size and shape.
Numbers must be placed as shown on the measurement diagram, centered beneath the Sunfish emblem (not biased out toward the leech), with numbers on the starboard side placed above the seam, numbers on the port side below the seam and numbers parallel to the seam.
Numbers provided on World Championship sails are considered compliant.
Digital numbers: as per a World Council vote in October, 2015, digital cut numbers are currently permitted.
