Thanks for your thoughts, @Christopher Walmsley.  To the question you pose regarding the situation where Yellow is 'moving slowly, or almost stationary' then I would suggest Blue has the option to 'pass' on either side but then has to satisfy 19.2 (a) and 19.2 (b).  Presumably if Blue chose to bear off and 'pass' a slow moving (or stationary) Yellow on their port side, remaining on port gybe, she is obligated to leave room for Green to do the same, 'unless she has been unable to do so from the time the overlap began.'   In our scenario, however, I would contend that they were unable to 'pass' Yellow by bearing off and only had one side they could have chosen. to 'pass'.  I do think they exercised a third option .... to 'avoid' by gybing which, as ROW boat they were free to do.  If they chose instead to 'pass' Yellow on their starboard side (the only side they could 'pass' the obstruction in this case) by heading up, then Green is burdened potentially both by RRS 11 but also by 19.2 (b).

That leads to one further question in my mind.  We don't know how the overlap between Blue and Green came about, however if Blue came from behind to establish the overlap (before the diagram starts), are they relieved of their obligation under RRS 17 with regard to Green by RRS 19.2 (b)?   She certainly sails above her proper course to take Yellow's stern if she heads up to do so.   

Thanks Satish.

Since you have reached a Case 50  conclusion so clearly, can you address these points I have.

1.  Yes, there was apprehension but what makes it so clearly 'reasonable'?

2.  Where in Case 50 (or the rest of the Casebook) does it suggest that Case 50-Reasonable apprehension  can be applied in rule 11 situations?

Niko, 

I'm still thinking about your post. Actually, I'm not sure you can presume that W was not in control simply because her move was hard and tightly timed.

I think the problem is my word 'just'. Let's just take it out.

Just before she thinks that RoW may need to act to avoid contact, W acts by luffing hard.

Meanwhile, can you think of any time RoW had no need to take avoiding action, but still have a reasonable apprehension ...? Or are the two mutually exclusive by definition? 

Beau ... here is maybe how I'd look it.

Let's say for the sake of argument that a boat doing 1/2 of a roll tack from a standstill is going to be hard to enforce.  So .. let's say 1/2 roll tack that is part of a boat's "start" is going to be not called. So what are the components of that?

So, when does one call it?  When those elements are not present. 

"If the details included remove any ambiguity about which incident the delivered protest is referring to"
Clear as mud.
Does not answer the question.

Yes we've used W finishes for many fleet events.  It works well for the back of the fleet. Not entirely sure the front of the fleet would be thrilled at having it used if they weren't 100% sure they were being recorded at the front.

I realise handicap racing is not popular on this board. For reference - W finishes are not appropriate in handicap races as you need to adjust time and 'distance' (laps).
