John re: "I can't believe that anyone reading Case 78 would remain in any doubt. Was there some more background?"

Nope. Just thought others might benefit from considering the questions for themselves and reading the answers/opinions of others.  

Correct.  Discards are just that - discarded. So for e.g in a 4 race series with 3 to count a boat with scores of 1, 1, 3, 25 is tied with one on 1, 1, 3, 4 - at which point A8.2 comes into play and the latter boat wins. 

Perhaps you can give us more context to explain any confusion? 

Gordon - while you might not like the term 'unbreaking', I would argue that it is appropriate.  When a ROW boat alters course and is no longer giving the KC boat room to keep clear, she has broken rule 16.1 at that moment.  That is what the words of the rule say.  However, if the ROW boat continues to change her course and later is giving the KC boat room to keep clear then we say that she has met her obligations overall.  The rule was 'broken' and then 'unbroken'.

Diego - yes, I get that in match and team racing part of the game is allowing the boats to get closer together than you would in fleet racing.  For fleet racing WS Case 103 helps us understand 'in a seamanlike way'

CASE 103
Definitions, Room
The phrase ‘seamanlike way’ in the definition Room refers to boat-handling that can reasonably be expected from a competent, but not expert, crew of the appropriate number for the boat.

But I'm not sure how this changes things other than to say that P breaks rule 10 earlier in the scenario, possibly at position 1.

Hi all,

Ric of course, thank you very much. I updated the fix. Spinning the boats fast should be now with expected result.

Next step in development will be a feature to record step by step movements, and be able to share this without login.
