The rules of Part 2 apply between boats that are sailing in or near the
racing area and intend to racing, are
race or have been racing. However, a boat not racing shall not be penalized for breaking one of
these rules, except rule 14, when the incident resulted in injury or serious damage, or rule 23.1.
When a boat sailing under these rules meets a vessel that is not, she
shall comply with the International Regulations for Preventing
Collisions at Sea (IRPCAS), or government right-of-way rules. If the
notice of race so states, the rules of Part 2 are replaced by the rightof-
way rules of the IRPCAS, or by government right-of-way rules.
