P5.2 Before the Starting signal

1. The race committee may signal that pumping, rocking and ooching are permitted, as specified in the class rules, by displaying flag O before or with the warning signal.
2. If the wind speed becomes less than the specified limit after flag O has been displayed, the race committee may postpone the race. Then, before or with a new warning signal, the committee shall display either flag R, to signal that rule 42 as changed by the class rules applies, or flag O, as provided in rule P5.2(a).
3. If flag O or flag R is displayed before or with the warning signal, it shall be displayed until the starting signal.
