This covers shortening the course for Saturday series races. Sailing Instructions (Full and Cockpit versions) on the Yachts – Racing Information page have been updated. Changes in bold type.
14. Shortened Course.
a. If a course is shortened after the start, Code Flag ‘S’ displayed at a rounding mark indicates that the course has been shortened. All yachts after rounding the mark shall proceed directly to the finishing line. If a Division Flag is also displayed with Code Flag ‘S’, the course is shortened for boats in that division only.
b. The course may also be shortened either at a mark of the course or other suitable location. The Start boat will fly a Blue Flag to signal they are on station and Code Flag ‘S’ at the finish. Yachts should pass between the club mark and the start boat from the direction of the previous mark of the course.
20. Finish Line.
a. When finishing, boats must pass between the Club mark and the Blue Flag on the Clubhouse mast or on the Blue Flag on the club launch. The Clearance mark does not apply at the finish.
b. Where the finish is from the Club launch the line will be set at an appropriate position relative to the last mark passed. The Start boat will fly a Blue Flag to signal they are on station and Code Flag ‘S’ at the finish.
c. When a finish buoy has been set a yacht must not re-cross the finish line after it has finished (pass around the buoy end of the line). Also see SI 26(b).
d. In Twilight and Saturday Races, a finish line may be set from the club launch without a pin end buoy. Code Flag ‘S’ and the Blue Flag will be flown from the club launch and the line set between the launch and either the green navigation buoy at Greenwich Point OR the green navigation buoy at Balls Head OR the ferry wharf at Longnose Point OR the flag mast at Hunters Hill Sailing Club OR the flag mast at Balmain Sailing Club depending on the last leg of the course being sailed.
e. Note: RRS. Rule 31 applies at the finish.
