• 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?

• Mark-Room and Room to Pass an Obstruction who wins.
  Rule 19.2(b) is premised on there being an “inside” and an “outside” boat. Sleigh Ride is aiming at the Christmas Tree and needs to commit to passing on one side or the other. It is reasonable for Polar Express to assume that Sleigh Ride will pass to leeward of the Christmas Tree on the “outside.”

  
  

  We don’t know when or how the overlap began, but at position 1 it is possible for Sleigh Ride to slow and let Polar Express pass to leeward of the Christmas Tree. So rule 19.2(b) applies and Sleigh Ride is able to give the Polar Express, the “inside” boat, room between her and the obstruction.

  
  

  Sleigh Ride still has mark-room so Polar Express must make a wide rounding to comply with rule 18.2(a)(1).

• 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?
