When a protest committee finds that in a port-starboard incident S did not change course and that there was not a genuine and reasonable apprehension of collision on the part of S, it should dismiss her protest. When the committee finds that S did change course and that there was reasonable doubt that P could have crossed ahead of S if S had not changed course, then P should be disqualified.
A protest committee must find that boats were exonerated at the time of the incident when, as a result of another boat’s breach of a rule, they were compelled to break a rule.
Rule 16.1, Changing Course
Rule 16.1 does not restrict the course of a keep-clear boat. Manoeuvring to drive another boat away from the starting line does not necessarily break this rule.
A boat clear ahead need not take any action to keep clear before being overlapped to leeward from clear astern.
Rule 20, Room to Tack at an Obstruction
Interpretation of rule 20’s requirements for hails and signals and their timing.
Withdrawn for Revision
Reasons for withdrawing Case 55 [RRoS.org Note: Reason as given in 2021 Case Book]: New rule 64.1(c), taken together with rule 63.1’s last sentence, required the protest committee to open a hearing of boat A’s protest. Also, the appeal by boat B should not have been heard by the national authority because it was not a valid appeal under rule 70.1(a). The case contains valuable material, but it needs to be extensively revised so that all of the interpretations of rules in the case are correct.
Deleted
When a current, properly authenticated certificate has been presented in good faith by an owner who has complied with the requirements of rule 78.1, the final results of a race or series must stand, even though the certificate is later withdrawn.
If a buoy or other object specified in the sailing instructions as a finishing-line limit mark is on the post-finish side of the finishing line, a boat may leave it on either side.
Rule 18.2(a)(2), Mark-Room: Giving Mark-Room
When a boat comes abeam of a mark but is outside the zone, and when her change of course towards the mark results in a boat that is in the zone and that was previously clear astern becoming overlapped inside her, rule 18.2(a)(2) requires her to give mark- room to that boat, whether or not her distance from the mark was caused by giving mark-room to other boats overlapped inside her.
