Accelerating rapidly, for me that is different for each class, depending on mass. In longer wavelength waves a Dragon will accelerate with a wave as the stern lifts. Look at the picture, there is a difference in the horizontal angle of the hulls, that must change boat speed per wave. Does that permit one pump per wave to initiate surfing/surging ? Do we take into account the mass of the boat? Accelerate rapidly (for a Dragon)

We will continue to support importing competitors from other scoring applications.  And that includes getting handicap info when we can.  But we don't intend to import scoring data unless there is some compelling reason.  If you're using SailWave, you can continue to move competitor data between the applications.  But you will still publish results from SailWave.   And you can continue to import .xlxs files for importing competitor data.  

Thanks Ben ... yea .. you asked how the reasoning would go and I obliged :-)

I don't think this is quite right.  It is making a RRS 2 protest look like a RRS 69 hearing which it is not.

I agree that a breach of RRS 2 that affects the fairness of the competition on the water will usually be accompanied by a breach of Part 2, but even if it is not, a breach of sportsmanship that affects the fairness of the competition is nevertheless an incident in the racing area and requires a hail of 'protest' and if necessary display of a flag.

Agree, and in OP case, I think we have

Boat B broke RRS 2.  RRS 36(b) does not exempt a RRS 2 breach.  On valid protest B should be DNE.

A lot of chat for a rather simple case.

To me... there are 2 halves to OPs question...

1st half - was Red racing?  Yes.  Her stern was still on the finish line when she broke rule 10.

2nd half - Did Red tack and gybe in accordance with 44.2...namely 'promptly' after the incident? This question is subject to the protest system, just like any other allegation of a breach of a rule not exonerated.

So the RC registers her second crossing i.a.w. Finish (a), and if anyone (RC or another boat) is unhappy about it, they can protest her for not exonerating 'promptly'.  Otherwise her 2nd crossing finish stands.

-------------------------
As for the r23.1 discussion, Racing is a time-block from time-a to time-b.  Once you pass time-b it's over.  You can't restart.  If Red had met the interpretation of Case 127, then she was past time-b.  Not racing.

If a boat not racing breaks a rule, then apply RRS 60.5(c)

If a boat has broken a rule when not racing, her penalty shall apply to the race sailed nearest in time to the incident.

What am I missing?
