44.3 Scoring Penalty
(a) A boat takes a Scoring Penalty by displaying a yellow flag at the first reasonable opportunity after the incident.
(b) When a boat has taken a Scoring Penalty, she shall keep the yellow flag displayed until finishing and call the race committee’s attention to it at the finishing line. At that time she shall also inform the race committee of the identity of the other boat involved in the incident. If this is impracticable, she shall do so at the first reasonable opportunity and within the time limit for protests.
(c) The race score for a boat that takes a Scoring Penalty shall be the score she would have received without that penalty, made worse by the number of places stated in the sailing instructions. However, she shall not be scored worse than Did Not Finish. When the sailing instructions do not state the number of places, the number shall be the whole number (rounding 0.5 upward) nearest to 20% of the number of boats entered. The scores of other boats shall not be changed; therefore, two boats may receive the same score.
