• Mark-Room and Room to Pass an Obstruction who wins.
  Jonah, i think there is a fallacy in the logic of applying these two rules simultaneously as opposed to sequentially as written. This to me is the crux of the problem:
  The first rule in sequence to trigger all other Obstruction rights and privileges is 19.1 .
  The very first condition is : Rule 19 applies when TWO boats are AT an obstruction. SR was never AT the tree, never needed to be AT the tree, and the tree's presence did NOT interfere with SR sailing the course. This is an indesputable fact. 
  
  The next applicable rule in sequence, is 19.2a.
  The rule is : A right of way boat may chose to pass an obstruction on her port or starboard side...... If under 19.1, SR was never the boat AT any obstruction in its course, then subsequent provisions of 19.2.a aren't needed. The only boat AT the obstruction after 19.1 is applied, is PE. Since PE is not a ROW boat, is fails to qualify under 19.2a to having a choice at its obstruction. It is still obligated to keep clear of SR. Nothing has changed that pre-existing obligation.
  
  If applied sequentially, the problem between SR and SE goes away in this scenario. No boat would have broken a rule; the ROW boat would be given its ROW and Mark Room, and the Keep Clear boat had kept clear and had room to pass its obstruction. Although PE was not on the best side of the tree tactically, but sometimes a keep clear boat may not have a right to choose (19.2.a) and suffers from a tactical error.

• Measurement Basis of Hull Length or Hull Lengths and Associated Rules
  I'm not sure that the recent revisions involving hull have been an improvement. We have the situation where bowsprit doesn't count for over the line or hull length, but does count for overlap. And ERS isn't that helpful when it comes to hull length. If you take a modern 18 or other similar craft there's a nominally vertical stem, but a tube projecting from that, with bracing structure both beneath and to each side. Throroughly part of the hull. OK, count it as bow sprit. Maybe. But in other classes you have exactly the same, but a solid construction. Look at these two. Where, in ERS terms is the bow on each, and how on earth do you tell who is over if you are sighting a busy startline?

• 1.1 Helping Those in Danger and Redress Race Time Adjustment
  Very practical method Alan - and 'refreshing' (for the routine ones I have PC experience in, we just did the corection calcs within ourselves - this case a major one) - for ourselves, easy enough to submit to the PC, when national level racing, as we always log all such baseline performance & tracking data from the onset of every race (and event YB Tracker always used etc).

• Rule 55.2 One Spinnaker Pole or Two?
  Gary, the issue is not whether the spinnaker is asymmetric or not. It is about the attachment of the pole to the sheet or clew of the spinnaker (RRS 55.3).
  
  Old sailors might say 'one clew of the sail must fly free'.
  
  In your 18 footer illustration, the tack of the spinnaker is on the pole, however complicated the guying/bracing arrangement of the pole may be, but the clew and the sheet are not attached to anything exerting outward pressure.

• "Rules Governing the Duration of Flag D Display Ashore Before Start"
  Andreas, I don't agree that illustrations of flags used should not be included in SI.
  
  RRS Race Signals includes pictures of all flags referred to.  That indicates that the SI, when prescribing a new flag signal may do the same.
  
  I've frequently seen flags to be used, and actual marks, being displayed at Competitors' Briefings.
  
  Why is this a bad practice?
