Each boat’s series score shall, subject to rule 90.3(b), be the total of her race scores excluding her worst score. However, the notice of race or sailing instructions may make a different arrangement by providing, for example, that no score will be excluded, that two or more scores will be excluded, or that a specified number of scores will be excluded if a specified number of races are completed. A race is completed if scored; see rule 90.3(a). If a boat has two or more equal worst scores, the score(s) for the race(s) sailed earliest in the series shall be excluded. The boat with the lowest series score wins and others shall be ranked accordingly. 
 

This Low Point System will apply unless the sailing instructions specify another system; see rule 90.3(a).

Each boat starting and finishing and not thereafter retiring, being penalized or given redress shall be scored points as follows:

 Finishing place       Points
  First                           1 
  Second                      2 
  Third                          3 
  Fourth                        4 
  Fifth                           5 
  Sixth                          6 
  Seventh                     7 
  Each place thereafter Add 1 point 

 

A boat that did not start, sail the course or finish or comply with rule 30.2 , 30.3 , 30.4 or 78.2 , or that retires or takes a penalty under rule 44.3 (a), shall be scored accordingly by the race committee without a hearing. Only the protest committee may take other scoring actions that worsen a boat’s score. 

A boat that did not start, did not sail the course, did not finish, retired or was disqualified shall be scored points for the finishing place one more than the number of boats entered in the series. A boat that is penalized under rule 30.2 or that takes a penalty under rule 44.3(a) shall be scored points as provided in rule 44.3(c).

If the notice of race or sailing instructions state that rule A5.3 will apply, rule A5.2 is changed so that, a boat that came to the starting area but did not start, did not sail the course, did not finish, retired or was disqualified shall be scored points for the finishing place one more than the number of boats that came to the starting area, and a boat that did not come to the starting area shall be scored points for the finishing place one more than the number of boats entered in the series.  

If the protest committee decides to give redress by adjusting a boat’s score for a race, it is advised to consider scoring her
