A group of skippers request the starter, who is a part owner of one of the requesting boats, impose the 'U' flag to prevent a pattern of dip starts by small boats in a small mixed club fleet of 7-10 boats.
Starting flags other than P-flag have not been utilized in the past in this event.
The starters agree to this request but the smaller boats are not forewarned, one of which, Boat-A, performs a dip start and sails the course unaware if a U flag was flown and is recorded by the RC as having started and also recorded a place. ie is not recorded DNS nor DSQ.
After the race a Boat-B tells Boat-A that the U flag was flown and they should retire. Another competitor, Boat-C, tells Boat-A an 'I' flag was flown and that Boat-A should retire.
No protests are lodged (and time limits have long since expired).
i. Is there any obligation on A to retire?
ii. If a group of competitors lobby a member of the RC to take certain action, such as to use a starting flag which is not customary for the event, and the RC agrees, is there any obligation by the RC to ensure all competitors are advised of the intended action?
iii What is the appropriate action if the RC awards a finish to a boat when another boat believes they didn't comply with RRS 30.3?
iv. Is owning an interest in a boat in a regatta a disqualifying conflict of interest for a race officer?
