This one has caused a fair amount of bar talk, no-one upset but unclear who is right or wrong..
Boat A on starboard gybe, marginal overlap with Boat B Boat B on port gybe Both boats approaching leeward mark on run to be rounded to port Boat A (potentially) in inside position Boat B (outside) enters 3 length circle Boat A calls starboard on Boat B while Boat A is still outside the three length circle If Boat A maintains the overlap it is obvious that she will shortly establish mark room rights, but is Boat A entitled to call starboard in the period before she has entered the 3 length circle? Any one have any thoughts?

In this situation Port/Starboard applies until the closest boat enters the zone at which point Rule 18 takes over and each boat then had different obligations which override port starboard. So as soon as boat B enters the zone rule 18 applies. The outside boat is required to give Mark-Room which is defined as below:
B does have to allow room for A to gybe (rule 18.4) but A (as I understand it) is not allowed to sail out wide and do a 'tactical rounding' they must sail directly towards the mark and is then entitled to proper course at the mark. A certainly should not have been calling starboard once B had entered the zone.

Strictly speaking the way the rules are written now they don't over ride port/starboard, they modify it.
So this is my understanding, Brass correct if necessary. Firstly the basic rules Before either boat enters the zone A is ROW boat, and stays ROW boat until she gybes: Rule 10. Once she gybes she becomes windward boat and loses ROW (Rule 11). RRS 15 never applies because B gets ROW because f A's gybe. However Section C may limit he actions of a ROW boat. Rule 18 applies So A is also entitled to mark room as soon as B reaches the zone, but at this point is still ROW boat, but cannot sail anywhere she likes because she is subject to rule 18.4, so she mustn't sail any farther from the mark than required to sail a proper course. Once A gybes she is no longer ROW boat and must sail straight to the mark. The subtlety is in A's proper course. My interpretation of this is that if A is high of the mark and without B there would sail two or three boat lengths past before gybing then she is entitled to do so, because its a valid proper course, and B has to stay clear of the starboard boat.

In general, Boat A is protected by 2 rules, 10 & 18, the double whammy, therefore Boat B needs to keep clear not just give room.
This is the ultimate overlapped leeward rounding. Cheers.
