Starlight vs. Bow #23

Another week and we had another arbitration hearing this time between Joe and Joseph in the 2nd race of Spring Series 2 Night 2. The arbitrator was Norm Smit.

Facts found:
1. Wind was 5-8 knots from the south.
2. On the first down wind leg of race 2 on May 24th, Starlight was on starboard tack approaching Bow #23 on a converging course.
3. At between 4 and 5 lengths from the leeward mark, which was to be rounded to starboard, Bow #15 had to alter course to avoid contact with Bow #23 amidships
4. Bow #23 did not alter course to keep clear of Starlight.

Rules that apply:
Rule 10, On Opposite Tacks; Rule 18, Mark Room.

Conclusions:
Rule 18 did not apply per rule 18.1 because the incident took place before at least one of them reached the zone.  Bow #23 did not keep clear as required by rule 10.

Decision:
By SI 11.4c Bow #23 is assessed a 30% penalty in race 2 on May 24th

This is a case where it must be determined if the boats were at the zone.  Clearly Starlight is entitled as right of way boat to sail her course as she pleases if they are both outside the zone.  If they are on opposite tacks outside the zone, there is no limitation requiring starboard to sail directly to the mark and give mark-room until one of them reaches the zone. Because of rule10, port must keep clear even if it means she is forced to sail further from the mark than she would like. Bow #23 would have been better served to gybe and keep clear.  She could have worked to maintain her inside overlap at the zone when they gybed back toward the mark.  This would have been a better play even if she felt they were at the zone. I suggest when you are burdened boat, when there is a doubt keep clear, don’t force the right of way boat to alter course.

By the way I think everyone should give their boat a name and send them to me.  I like writing these summaries with boat names rather than bow numbers. I don’t have names for Bow numbers 2, 19, 23, 24, 26, 30, 32 and 34.

  2. One thing to clarify here. #23 wanted to invoke "proper course" to the mark. And there IS a way she could have done that. IF an overlap is established "from astern" then the leeward boat MUST sail its 'proper course' - which in this case is the fastest course to the mark in the absence of other boats - IOW Starlight would NOT be able to take #23's presence into account.....

    So what #23 COULD have done is to gybe to Starboard, and very quickly turn her bow up so that her stern plane crossed ahead of Starlight. Then immediately turn back down and call for #23 to assume her "proper course".

    then when they entered the zone overlapped, #23 could call for "Room at the mark" - gybe to port, sail inside of Starlight, and gybe back onto starboard as part of the rounding.

    and also its fantastic to see the decisions being posted. Thank you Norm.

  3. Karl, but then could Starlight not jibe twice and turn off 17?

  4. Does this decision differ if the mark at the bottom is a finishing mark? What hails should be made to ensure that the port boat does not demand the right to finish. Our hail was to indeed suggest port boat gybe to starboard, there was room, and port boat ought to have seen that there would be a problem anyway long before yet chose to push for advantage in the finish.

  5. Sailsmart: There is no difference if it is a finish mark, the same rules apply. As the burdened boat port must keep clear even if it pushes her further from the finish than she would like.

    Dick: You are correct 23 did as Karl suggested, 15 could gybe twice and turn off rule 17, but in this case I believe she would be within the zone after the first gybe and need to give mark-room.
