An interesting development.

The trouble with such developments is you will start to get 100's of "what about this" scenarios. For example what happens if A5.3 is activated in the RRS.

I suspect you will get requests for some form of "import" of places/elapsed time. In my experience the challenge with all these things is how you match boats.

I'm also not sure you've mastered the handicap process. What you've described will work for some scenarios but it's clear from posts on here that the UK and AUS (at least) will use average lap handicap racing which means you also need a number of laps in the time entry. 

Having scored many a handicap race, use of hh:mm:ss entry makes entirely logical sense from a developer pe spective but is a pain for data entry. For several reasons. HH is relatively rarely entered in dinghy handicap races, and even a race going over 60 minutes might have a time recorded as 65minutes etc depending on how the finish boat watch works. But, also the use of : on a keyboard requires two hands. Use of a decimal can be done from the number pad. So some scoring systems allow the entry to be[H[H]].MM.SS format and the MM can be >60

Good luck with your developments. It does seem entirely logical that a single platform handles it all. 

I do not think there would be surfing here. They may accellerate as the wave passes, but this is not the rapid acceleration on the front of the wave.
If this seems an easy answer for the dragin i frequently consider it in lighter winds in the ilca class

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?
