Rule 6. The director, if he deems it necessary for safety, may require 1 or more marine enforcement vessels to patrol the course of the regatta or marine parade for the purpose of enforcing not only the limited restrictions, but also for assistance of persons or property in peril, and the enforcement of laws generally. Issuance of the sanction may be made contingent upon meeting the requirement for patrol vessels.
