The sailing instructions will consist of the instructions in RRS Appendix S, Standard Sailing Instructions, and supplementary sailing instructions that will be on the official notice board located at the club.


1. The schedule is as follows:

Competitors briefing: Friday, June 16th approximately 8:30 at Regatta Headquarters & on VHF radio.   

Warning signal for the first race: Friday, June 16th, 2017, 10:00 hours. 

The time of warning signals for subsequent races will be posted except when races are sailed back-to-back.  

Six (6) races are scheduled of which no more than three shall be sailed on any one day.  

On the last day of the regatta if three races have been completed no warning signal will be made after 12:00 hours.  If three races have not been completed this time limit is extended to 15:00 hours.


2. Notices to competitors will be posted on the Official Notice Board located at Regatta Headquarters. Channel 72 is the competitor’s channel. Signals made ashore will be displayed at a docked signal boat.  


3. Marks:

3.1 Original marks and change marks will be identified at the competitors briefing.

3.2 After the start, minor adjustments in a mark’s location will not be signaled.  This changes RRS 33.


4. Time limit: 90 minutes.  Boats still racing 30 minutes after the first boat sails the course and finishes will be scored TLE (Time Limit Expired), the position of the last boat that complies with RRS 28 to finish plus 2.  This changes RRS 35, A4.2, and A11.  


5. The starting line will be:

5.1 Between a staff displaying an orange flag on an RC boat at the starboard end and the port end starting mark, or

5.2 Between staffs displaying orange flags on two RC Boats, or

5.3 From a staff displaying an orange flag on an RC boat at the starboard end, to a staff displaying an orange flag on an RC boat in the approximate center of the start line, and thence to a staff displaying an orange flag on an RC boat at the port end. 

5.4 If a mid-line boat is in place in accordance with SI 5.3, yachts subject to the I Flag rule may return to the pre-start side of the line around the mid-line boat, leaving it to port as if it were the port end of the starting line before starting.  This changes RRS 30.1 

5.5 A boat that has not started before 5 minutes after her starting signal shall be scored DNS.


6. Recalls: Following the display of the Individual Recall signal, the RC will attempt to announce by VHF radio the sail numbers of all boats identified on the course side of the starting line at the start signal and boats that must comply with Rule 30.1.  Such announcements are a courtesy and failure by the RC to make the announcement, or of boats to hear and/or understand it, shall not constitute grounds for redress.  This changes RRS 62.1(a).


7. The finish line:

7.1 will be between a staff displaying an orange flag on a race committee boat and on the course side of a nearby mark, or between staffs displaying orange flags on two race committee boats.  

7.2 Flag A displayed, with no sound, while boats are finishing indicates “no more racing today”.  

7.3 Flag H displayed, with no sound, while boats are finishing indicates “racing will continue after a break either on shore or on the water”.

7.4 If no flag is flying it may be assumed that another race will follow immediately.

7.5 A boat that retires from a race is requested to notify a RC boat before leaving the racing area, or, if that is not possible, notify a regatta official at Regatta Headquarters immediately upon arrival on shore


8. Scoring:  RRS A2.1 is changed so that each boat's total score will be the sum of her scores for all races unless six races are completed. If six races are completed, each boat shall discard her worst score, except when prohibited under RRS 90.3(b).   Three races must be completed to constitute a regatta.  


9. Except in an emergency, a boat that is racing shall not make voice or data transmissions and shall not receive voice or data communication that is not available to all boats.


10. RRS 44.1 is changed so that the Two-Turns Penalty is replaced by the One-Turn Penalty.

11. The crew of a capsized boat or a crew member overboard shall be considered "in danger", and thus eligible to continue racing without penalty after receiving assistance. This changes RRS 41.

12. A boat intending to protest about an incident that occurs in the racing area shall notify the RC finish boat of her intention, including the sail number of the boat (s) being protested. This changes RRS 61.1 (a)
