• Rule 19 - "Pass' vs 'Avoid' Language
  I will return (with trepidation) to my original stance.  In this scenario, unlike on a beam reach for example, I contend that there is only one side that can be chosen by the ROW boat to pass the obstruction and where, therefore, RRS 19 applies.  Blue can chose head up and go behind Yellow.  In this instance, I think we all agree that the obligation is on Green (RRS 19.2b) to give Blue room to pass between her and the obstruction. Blue's obligation (RRS 19.2a) is to give Green room to keep clear as she changes course.
  If, however, Blue choses to avoid the obstruction by gybing, she is not passing the obstruction .... indeed, she is not able to pass the obstruction on her port side unless at position 1 she suddenly had a burst of speed and could cross Yellow.  Given that she is unable to pass the obstruction on her port side, she chooses, instead of heading up to pass on her starboard side, to avoid the obstruction by gybing.  Therefore in this instance, RRS 19 does not apply.  Returning to my original post, I believe this is why the language of 'pass' is not used in RRS 20.  
  
  In RRS 20 (sailing close hauled or above), there are things that have to happen for the ROW boat (leeward) to be able to safely maneuver to avoid the obstruction (again, it doesn't say pass).  Should she chose to avoid the obstruction by tacking (rather than passing it astern per RRS 19) she has to follow RRS 20.1 and things unfold from there.
  
  In our scenario, it seems to me that if the intent was that Blue had obligation to give room for Green to gybe between Blue and Yellow (obstruction), there would be another rule entitled ROOM TO GYBE AT AN OBSTRUCTION with a series of hails and responses.  This would be problematic however, for all the reasons that I stated in previous post (broken overlap; uncertain duration of right to room, etc.)  However it seems to me that this is NOT the intent since the ROW boat  going downwind already has the ability to execute the choice to avoid, rather than pass (which they don't going upwind without the protection of RRS 20), and the give-way boat already has the ability to pass the obstruction safely by heading up astern of the obstruction.

  Yes, if done correctly a roll tack can accelerate a boat substantially, but that kinetic seems to be acceptable in general practice if not linked to another immediate roll tack.
  
  I was trying (and not succeeding) in asking: Using the roll tack example, is it "ok" to do one crab? Is the foul when a competitor does multiple linked crabs?
  
  When watching ILCAs from the signal boat, there are lots (sometimes all) of the boats performing various maneuvers constantly for the last 20 seconds before the start. Bows are going up and down, sails are going in and out, and body weight is being moved inboard and out. None of that looks like crabbing to me. It's only when I see a boat backing its mainsail and skulling to get the bow down that I think it's a crab, and only when it's repeated do I think the boat is crabbing, similar to repeated and linked roll tacks. (All this said with the proviso that Rule 42 is not my strong suit as I'm more of a Race Officer vs Umpire.)

  I think the approach I've seen used is to tell them they have been finished on the previous lap. (Legally or illegally)
  
  I still think if we see the SIs it will clarify the situation with a phrase like 'The Race Officer may decide to finish boats at any time at his discretion. This may not be the lead boat, but results will be calculated on average lap time to ensure fairness, the aim being to keep the finishing window as short  as practicable' (I selected that frome Penzance Sailing Club who used it for handicap and non-handicap fleets) or from my club 'For a committee boat finish, flag S will be displayed on the committee boat accompanied by two sound signals. For a shore-based finish, two sound signals will be made. Boats will finish the race when they next pass through the start / finish line. Finishing position shall be determined on an average lap basis.'
  
  (Clearly purists will say start/finish line shouldn't be mentioned - but for an average club sailor that's clear and easier to understand than describing a gate. And for the even more purist, a Committee Boat should be called a signal vessel but I can say with certainty the club sailors know what a committee boat is and will think I've lost the plot if I say signal vessel.)

  It is simpler and more direct to add to radio sailing NOR or SI:
  "A protesting boat shall inform the other boat at the first opportunity. This adds to E6.3."
