Measurer’s Approval for Experimentation

§III-4.0 Basic Rules Governing Deviations from the Specifications: If a Fleet wishes to experiment with or otherwise permit a deviation from the Specifications, approval for such experiment or deviation shall be obtained from the National Measurer. The National Measurer may set certain terms, conditions and reporting requirements on any such experiment or deviation.

The use of a small spinnaker for local fleet racing is permitted for use as a training sail for the 2008 season. Approval is granted for individual fleets to adopt the use of a small spinnaker for use in Shields racing according to the following conditions:

  1. The use of the small spinnaker is only approved for racing within a local fleet and not approved for regatta use.
  2. The use or acquisition of the small spinnaker shall not be required of any registered yacht and shall remain strictly optional.
  3. The acquisition or use of a small spinnaker shall not change or be counted as to sail "credits" [Section V-1.0].
  4. The requirements for qualification of a registered yacht, skipper, and sails is unchanged in that the normal spinnaker must be raced in 10 races in order for it to be qualified for the National regatta. [Section VI-1.2(d)]
  5. The specifications for the small spinnaker shall be open to experimentation. The initial target is to have the sail approximately 25% smaller. In order to easily differentiate from the normal spinnaker when flown, the small spinnaker shall not include sail numbers [Section V-7.4].
  6. In order for a small spinnaker to be used in local racing, it must be adopted by the local fleet. The use details (when allowed, scoring, etc.) of the small spinnaker is left to the local fleets and should be made part of their Sailing Instructions.
  7. Fleet captains shall report to the National Measurer as to the use and recommendations related to the small spinnaker at the end of the season.
