Hi guys - I have been folowing this thread with interest. 
I think I understand both of the arguments being put. 
I think A felt under pressure to make the rounding and tacked slightly too early (thereby taking a risk) and this was at least part of the cause of A's slow and bad tack. 
I understand Simon's argument that if sailied differently (better), R might have successfully avoided the collision, but as the jury didn't seem to comment on the reasonablness of R's actions (unless you know differently), I certainly don't think any precident has been set regarding anticipating whether a boat will be sailed reasonably or in a seamanlike manner or whether it will be sailed badly.

This case is about A making a risky decision to tack and failing to give R room to keep clear.

You say A took a risky decision; IF R had sailed the boat properly there would have been no collision.  Thus no risk by A; as I stated above; R failed to sail the boat correctly and by their ineffectual action, the collision occured. 
 
So; in the case; are you stating (and I do want to understand this) that as long as R does SOMETHING to avoid A when ROW boat; and there is a collision then R is OK, even if they do not do what is reasonably expected of them (so in this case to not dump the jib and to dump the main to aid the the bear off). 
 
When I saw this happen; as soon as they dumped the jib I knew they were in trouble; you can see the rudders stall and that's it; they are passengers to the scene of the accident....

Sorry, I can't agree with that.
 
Rule 14 (llike most of the post 1995 rules) imposes an outcome-based obligation, 'to avoid contact', with a limitation or condition 'if reasonably possible'.  It does NOT mandate 'action to avoid contact'.
 
This may be contrasted with pre-1995 rule 32.1 which required a boat 'to make a reasonable attempt to avoid collision'.
 
Under rule 14 as it stands, if it becomes impossible for a boat to avoid contact, say because of a sudden round-up under her nose, she is not obliged to take any action or attempt to avoid for to not break the rule because of the impossibility.

OK; Given R did not sail the boat as any CAT SAILOR would expect, ie they dumped the Jib (thus making the bear-off difficult) and did not dump the mainsail (thus making it even more difficult). 
 
Does the poor boat handling of R (Dump jib; don't dump main) not have bearing on this?  it's my reading / understanding that R needs to take REASONABLE action to avoid A what is now on STBD; my point is that I believe dumping the jib, and not dumping the main, is NOT REASONABE action when attemping to bear off in a catamaran.   
 
IF the main HAD been dumped and the jib NOT eased, I firmly believe that they WOULD have avoided this collission. 
 
It's a moot point; but I believe has implcations for any close call in cat racing. 
 
thus
 
If I am A, do I have to assume that R will not act in a reasonable manner when bearing off? (and thus assume they will carry on on current heading and thus allow "extra" room.
IF I am R, Can I assume that I do not have to act in a reasonable manner when avoiding a boat that has tacked onto stbd (but may have stalled), and that if I do (dump jib/don't dump main) that I will be exonerated?
 
 
Given this decision, do we now assume boats will NOT take reasonable actions?

Totally agree with Brass - I should point out that the "Jury's findings" were an attempt to write up the incident as a Jury would have done, rather than a quote from an actual hearing!

Incidentally - rule 14 states "shall avoid contact with another boat if reasonably possible". The rule imposes an obligation to take action, not an obligation that the action should succeed!

On the other hand, rule 13 places an absolute obligation on the tacking boat to keep clear. If the tacking boat has not allowed enough room to keep clear if the tack is less than perfect that is her problem and no-one else's.

In this case, however, my reading of the incident is that rule 13 was broken almost immediately after A passed beyond head to wind. As soon as R reasonably felt it necessary to bear away, A had broken the rule. A's failure to accelerate out of the tack  did not break a rule, but rendered the collision inevitable.

I still hold the opinion that IF they had blown the main and not eased the Jib they WOULD have made the bear-off easily... (or they could have tacked) 

 
Reading (or writing) between the lines of the protest decision:
When R started to bear away after A passed head to wind, R had a reasonable apprehension of collision, which under Case 50 means that A had, at that instant failed to keep clear and broken rule 13.
 
R bore away to a course that,  had A accelerated normally out of her tack, would have been sufficient for R to pass behind A.
 
A stalled and did not accelerate normally out of her tack.  It was only at this point that it became clear to R (or anybody else) that A would not keep clear of R's new course.  This was the point at which time starts to run for R to avoid contact under rule 14(a).
 
Starting from the point where it became clear that A was not accelerating normally out of her tack, it was then not reasonably possible for R to further change course or take any other action to avoid contact.
 
R did not break rule 14. 
It's not clear who Simon is referring to when he says "we HAVE TO ASSUME that crew(s) will not sail the boat properly and thus allow room".
 
The protest decision did not address 'room'.
 
With regard to A, when she reached a close hauled course, she would have had an obligation under rule 15 to give R room to keep clear, but by that time, A had already failed to keep clear of R thus breaking rule 13.  Once a boat has broken rule 13, there is little point in going into whether, in the same incident, but a few seconds later, having gained right of way, she also failed to give room to keep clear.
 
With regard to R, when she first bore away to avoid A, she had an obligation under rule 16 to give A space a she needed [to keep clear of R] in the existing conditions while manoeuvring promptly in a seamanlike way.  Arguably A's failure to accelerate normally out of her tack was not manoeuvering promptly in a seamanlike way, thus R did not fail to give A room to which she was entitled, and R did not break rule 16.
 
Simon is entitled to his opinion but, given that he was not in a good position to observe the incident directly and did not hear the evidence given to the protest committee, there is no reason for the rest of us to prefer his opinion to the opinion of the protest committee.

In the somewhat curt words of a Jury's findings:

Facts found: On a beat, with both boats on port, A was clear ahead of R. A luffed and passed beyond head to wind. Before A reached a close-hauled course, R, now on a collision course, started to bear away. There was contact, causing considerable damage to both boats, between A's port quarter and R's port bow.

Conclusion: A, whilst tacking, did not keep clear of R. A broke rule 13.
R, right of way boat, took action to avoid contact when it became obvious that A was not keeping clear but was unable to avoid contact. Rule 14(a) applies. A rule 44 penalty is not appropriate as A's breach of rule 13 caused serious damage (44.1(b)

Decision:  A is disqualified
