• Mark-Room and Room to Pass an Obstruction who wins.
  Mark, 
  Agreed at position 2 Polar Express's course is being influenced by the obstruction so rule 19 applies but case 150 isn't required to clarify that part of interpreting 19.1
  
  Respectfully, that case 150, is predicated on a continuing obstruction influencing the course of both of boats. In the context of this tree scenario, and as i have interpreted facts from the diagram, SR did not alter course to avoid the tree. Is was bearing off before the AT was reached FOR  SR . The tree was never influencing SR's course around the mark. It never had to sail through the position of the tree. 
  
  To say the tree was an obstruction to SR is factually and in reality, incorrect. With respect to case 150 clarification of AT, the case is dissimilar to the tree scenario. Case 150's scenario is a continuing obstruction that is actually affecting the course of both boats but in different ways to the tree. In Ans 2, W as keep clear boat IS constrained by the breakwater to luff up to avoid L on its current course, and their overlap gives L no option to gybe to keep clear of L. 
  
  This  tree scenario is very different : PE is not constrained by the tree to avoid SR. As shown, they were free to luff up. In case 150, W can't luff up into the breakwater and neither is it clear they can they safely gybe to keep clear of L.
  
  150's answer to Q1 and Q2 is akin to shoe horning those conclusions in into this tree scenario and telling the skipper of SR " the tree is in your way" when the actual facts shown are that it was never in the way, and PE was not constrained by the tree obstruction to keep clear of SR. Those are facts which don't fit the facts of 150, so in my mind, 150's conclusions aren't applicable. There's no safety issue to either boat, if PE simply keeps clear of SR under RRS 11 as it is free to do, and gives mark room under 18.2.a.1. 
  
  It all hinges on 19.2.a,) as it is currently written, where PE as  the keep clear boat, is NOT eligible to choose. Therefore as it's already obligated under 11 and 18, its only choice is to luff up or slow down and follow SR.
  
  After 19.2.a limits PE's choice, by applying 19.2.b. to SR which was not AT the tree, creates instant / unseamanlike course complications and safety issue for SR in this scenario.
  
  How about this tree case spawning a new rule:
  18.1.c: if the zone of a mark contains within it, an obstruction affecting any boat's course through the position of the obstruction, then Rule 18 does not apply and Rule 19 applies from the point at which a boat enters the zone.

• 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?
