ISAF Q&A 2009-025

In continuation from Q&A 2009-020, this one is again about a three boat situation at a mark. This time at a windward mark.

The questions are about the rights a boat has, while sailing on a proper course as inside boat, while having mark-room from a second boat, in regards to a third. Download the ISAF Q&A 2009-025 here.

In contrast to Q&A 2009-024 these answers are pretty straightforward.

In both scenarios rule 18 does not apply between the boat with mark-room from a second boat, towards a third. Therefore al normal rules apply including restrictions under 15 and 16.

I’m taking both Q&A’s (024 & 025) with me to a presentation I’m giving to a group of sailors tomorrow evening. To see how they react to these – in my opinion fairly frequently occurring – scenarios.

 

Q&A 2009-025 pictureOn a side note. Both pictures in the Q&A are drawn with boats and symbols I haven’t seen before. It isn’t TSS or Boat Scenario.

And it isn’t Angelo’s Protest Diagram Kit v2.doc.

 

Does anybody recognize the program these diagrams are made with?

  1. I perceive a big difference between Q&A 2009-024 and Q&A 2009-025.

    024 addressed a really difficult situation and provided useful clarification (although I can't say I have 'got my head around it' even yet.

    025 seems to be answering questions that need never have been asked: all that was necessary was to apply the rules as stated. These situations are handled consistently in any number of rules commentary books.

    The Q&A panel has already, in three months, produced more Q&As than were produced in the preceding five years: if they go on at this rate, we will soon have more Q&As than cases or rules.

  2. Agin the answers give rise to other questions.
    The answer to Q 1 is correct as far as it goes but it is silent on rule 19. Surely rule 19 applies between A and B (in relation to C) and if B does not give room for A to pass behind C then maybe B does cause A to break rule 10. It is not (as the answer implies) just mark-room that needs to be considered in this case. Whilst the Q and A committee may have answered the question as asked I do not find it particularly helpful if only a part answer to the scenarios is given as people start to use the answers as gospel.

  4. Uli Finckh (the German rules pope) uses these drawings on his own website: www.finckh.net

  5. Why we need rule 18.5(b) for exoneration of a boat, if no other boat breaks a rule?
