I have seen a few interactions recently between boats that are racing and boats that are not. The preamble to Part 2, the right-of-way rules, says that the rules of Part 2 apply to all boats who are racing, intend to race or have been racing, as long as the boats are in or near the racing area. The preamble also says that a boat not racing will not be penalized for breaking any of the Part 2 rules except rule 14 or 24.1.
