Individual Recall
When at a boat’s starting signal any part of her hull is on the course side of the starting line or she must comply with rule 30.1, the race committee shall promptly display flag X with one sound. The flag shall be displayed until the hull of each such boat has been completely on the pre-start side of the starting line or one of its extensions, and until all such boats have complied with rule 30.1 if it applies, but no later than four minutes after the starting signal or one minute before any later starting signal, whichever is earlier. If rule 29.2, 30.3 or 30.4 applies this rule does not.
