  • Tim, your interpretation of rule 19.1 conflicts with WS Case 150 answer 1. "Boats are ‘at’ an obstruction when they are near it and the obstruction is influencing the course of one or both of them." 

    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 indisputable fact.

    At position 2 Polar Express's course is being influenced by the obstruction so rule 19 applies. WS Case 150.

    When boats are overlapped at an obstruction, including an obstruction that is a right-of-way boat, the outside boat must give the inside boat room between her and the obstruction. WS Case 11.

  • 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?

  • 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).

  • 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.

  • 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?
