• New Hailing Requirement in rule 20.1
  So I’m struggling with the idea that 20 doesn’t apply if they don’t use the words ‘Room to tack.’ Given that 20.2(b) says that the hailed boat shall respond even if the hail breaks 20.1 implies even if they don’t use the prescribed words they still shall respond.

• Leeward Mark Proper Course vs Seaman-like
  I've ended up confused by this discussion.
  
  The comments use the terms proper course, seamanlike turn, and tactical turn. Proper Course has a definition in the rules. Manoeuvring promptly in a seamanlike way is mentioned in the definition for Room but "seamanlike turn" is not defined. Similarly, "tactical turn" is not defined.
  
  Case 75 relates to a slightly different situation, since S gybes in the zone and there was contact. However, the discussion in Case 75 says "When S gybed just after position 2, she had not sailed farther from the mark than needed to sail her proper course. Indeed, in the absence of P (the boat "referred to" in the definition Proper Course), S's proper course might well have been to sail even farther from the mark and higher than she did, so as to make a smoother, faster rounding...". Doesn't this mean that S's proper course was what might be labelled a tactical turn?
  
  Then USA Appeal US20 says "Mark-room is not defined to allow an inside boat without right of way to sail to a mark in a tactically desirable manner", which seems to contradict Case 75. Additionally, is this appeal relevant to everyone, or just those who sail in the USA?
  
  I'd be grateful for any further clarification.

  @Dustin: Agreed, on tactics: 
  
  Red could try to go on as long as possible on starboard, keeping clear of Green, but not tacking. Gets tricky when Green fights back luffing, and both boats end up standing still head to wind side by side, Red needs to keep clear then even if they start moving backwards… 
  
  Maybe after being luffed by Green, Red has a bit of a chance to tack just before it stops moving into the wind, going down as far as needed to break the overlap to Green and trying to speed up and stay ahead on port to avoid reestablishing of an overlap. 
  
  Green would tack and not go down (i.e. follow Red), but sail close-hauled to the mark to re-establish an inner overlap asap (18.2(c)). Would be difficult for Red to argue she had not been able to give that mark-room (see 18.2(d)). 
  
  The rest has been discussed above: Green has advantage in all following constellations. 
  
  Overall, Green seems from my POV to have the better options to be first after this mark, whatever Red does from the moment they entered the zone. 
  
  Ideas?

  I wonder how ChatGPT would do reconciling last year's NOR and SI with this year's template. I will try to find out at some point this spring.

• Rule 2/69 Question
  Paul .. re: "And Angelo for pointing out where a protest may be between two boats, it might impact other members of the fleet."
  
  I've got an entire elevator-pitch.  :-)
  
  In  my old post, I have a section on "I owe you one", which touches on the same concept we are discussing, being we can (and should) assume that a boat which breaks a rule (and is not exonerated) gains an advantage against other boats in the fleet. 
  
  Doing so, puts this entire topic into a firm frame.
  
  Here is a little diagram that I use to help make the point.  Blue, Yellow, Green and Red are basically even in the same race.  Blue, Yellow and Red each have 1 duck each .. so in our perfect sailing imagination, they are even at position 10.  By Yellow & Blue's unsportsmanlike "I owe you one" compact on the course, they both gain an advantage against BOTH Red and Green on the opposite side of the course, because both Blue and Yellow should be where Green is.
  
  Of course .. Blue and Yellow wouldn't have had the 2nd close-cross at #8 if Yellow protested and Blue did her turns after #4  .. that's true so the diagram isn't perfect ... but I think it still helps makes it's point.
  
  Now .. anytime I put this drawing up, people immediately start-in with .. "How about if Yellow waived Blue through a #4?  Huh??  How about that?".  Well .. that's not the scenario I'm proposing"  For the drawing below, assume both Yellow and Red want their port-boats to either duck them or tack.
