Class rules: "Note: SPL and ISP should be used to calculate spinnaker dimensions." TACK LINE/SPL RULE CLARIFICATION to Appendix A5.5.5c “Owners may tack an asymmetrical spinnaker 6” in front of their rated SPL on boats that use a spinnaker pole to fly an asymmetrical spinnaker so that they are able to jibe it in front of their bow pulpit. Besides fastening a block for a tack line to the existing structure, the boat may not be modified to achieve this objective without invalidating their rating certificate. Boats with bow sprits whose tack points are already in front of their bow pulpits may not move their tack lines beyond their current tack point (SPL) without invalidating their rating certificate. Boats whose poles that exceed the “J” dimension may not add structure or a bow sprit to achieve this objective without invalidating their rating certificate.” |
