In this scenario Yellow and Green are sailing downwind on port tacks.  They must round a mark to port in light wind.  When Yellow enters the zone, she is clear ahead of Green. When Green (2) entering the zone Yellow is rounding the mark and tacks to starboard. Yellow (3) sail on starboard tack and Green (3) had to heads up to avoid Yellow. There was no contact put, Green (4) hit the mark and took a one penalty turn.

Is Yellow required to give mark-room to Green so she can sail  their proper course without interference from Yellow?

Olafur, the scenario looks more straight forward to me.  

  1. Yellow is entitled to MR from Green from before pos 1 (when she entered the zone) thru pos 2.5
  2. At pos2.5, Yellow passed HTW, her MR ends under 18.2(b)
  3. From pos 2.5-3.0 Yellow is KC boat under RRS13
  4. From pos 2.5-3, Green (ROW under 13) alters course to avoid Yellow. 
  5. Yellow breaks RRS 13 and is not exonerated.

Mark room does not apply to one boat leaving the mark and another approaching the mark - so mark room for yellow ends once she passes the mark (and before she tacks). So R 18 and proper course do not apply - so R 13 and R 10 are applicable and then R 15 as ROW changes - Angelo thinks Yellow broke R 13 at around P2.5. I would add that Yellow breaks R 15 even if she did not break R 13.

I won't repeat what Angelo said. Rule 18 turns off as soon yellow leaves the mark clear astern, whether she tacks or not. 
I cannot tell from the diagram whether green has to alter course before yellow has born off to close hauled. If it is established as a fact that she did, then Angelo is correct.
But, even if yellow completes the tack before green has to alter course, there is still rule 15 to deal with. 
After yellow has completed the tack, she "initially" owes green room to keep clear (which green apparently does get) AND room to comply with the other rules of part two and rule 31 (avoiding hitting the mark). 
It does not appear that sufficient room was given for green to comply with rule 31, by maneuvering promptly in a seamanlike manner. 
If the facts found are that the tack is completed in time, the PC could still DSQ yellow for breaking rule 15.

Anthony, I don't agree with your RRS 15 analysis relative to the mark.

Yellow does not owe Green any mark-room.   After position 3, Green chooses to turn back toward the mark to attempt to round it on its proper side .. she was not compelled to do that and was not owed mark-room by Yellow to do so. 

I think it's clear, based on the drawing, Green altered course before Yellow completed her tack.  There is no contact and there is no claim that Green maneuvered in an unseamanlike way. Therefore IMO 15 was not broken by Yellow.  Green had room and used that room to keep clear once Yellow completed her tack (after Yellow broke 13). 

OK .. for the sake of argument, let's say that Yellow DOES complete her tack before Green alters course ... and Green is able to keep clear in a seamanlike way .. what then?  If that tack was clean .. and Green could keep clear in a seamanlike way ... I don't see Yellow breaking a rule. 

PS: Unless u argue that is Yellow was not sailing her proper course by tacking.  Then one might apply RRS 23.2 Interfernce as they are sailing on different legs of the course.

I think it's a bit simpler than that.

@4 when G touches the mark Y is 2.5 boat lengths away.  You can't say she is not giving G room to not touch the mark.

Angelo.
Regarding your last "PS," I think rule 23.2 could only be invoked if the course to the next mark was a port fetch. We disagree on how clear the diagram is as to when green had to alter course and whether it happened during yellows tack. That certainly could be the case and your analysis is correct if it is. I just would want more information before I signed off on that.
I take your point about 15. We agree Green was given room to avoid yellow after yellow tacked and it seems green avoided in a seamanlike manner. Upon reflection, I agree with you that Yellow's rule 15 obligation does not extend to giving her room to turn and round the mark. Green was given room to avoid hitting the mark. She chose to try to round. 
In that case, since green did her 360, there would be no foul here.

I find this situation interesting as it happens a lot on Wednesday nights where I race. I guess the question here is really the timing around positions 2 and 3. If green alters course before yellow has established itself on starboard then there is a problem (rule 13) or just afterwards (rule 15). If yellow informs green that they are tacking right away after rounding does that satisfy rule 15? There seem plenty of room and opportunity to windward for green to avoid yellow. The fact that green gybed too late and stuck the mark was their decision.

Dom .. regarding hailing.  

Hailing can be one act a boat attempts to avoid contact with another boat.   However hailing doesn't buy you extra rights or satisfy a requirement when one boat may owe another boat RRS 15 room in the future. 

RRS 15's room has to be given, regardless of any announcements made.   15 doesn't apply until Yellow completes her tack.  Announcements made prior to tacking have no "power". 

A boat tacking inside the zone into oncoming traffic is executing a dangerous and rule-risky maneuver.  Case 50 will be on the side of the non-tacking, approaching boat .. as it will be not too high a hurdle to convince a jury that they had "reasonable apprehension" for a course change when a boat is tacking into their face (as illustrated in the OP diagram)

RRS 18.1(a)(3) is specific in saying that rule 18 does not apply between a boat approaching a mark and one leaving it. So in this case tacking in the Zone has no further implications past rules 10, 13 and 15. In the OP's diagram it's not clear when exactly Yellow established starboard tack... and that's the real rub here. Though at point 2 Yellow is shown tacking and Green is just over three boat-lengths away. I would think in a low wind situation that Green would have had significant opportunity to identify that Yellow was tacking and to keep clear of the starboard boat. Yellow hailing as they tack would give Green even more opportunity.

Please go back and re-read. 'When Green (2) entering the zone Yellow is rounding the mark and tacks to starboard.'  Yellow is now in stbd, in light air and 2-2.5 bls from green. IMO yellow is in the clear and green owes penalty turn to exonerate hitting the mark.  Diagram shows green hitting the mark, not yellow as the description says.

I'm with Sue, up to a point.

Here's my analysis.

At the time of the incident RRS 18 does not apply between Y, leaving the mark and G approaching it (RRS 18.1(a)(3))

Y, leaving he mark is on a different leg to B approaching the mark and is required to avoid interfering with G unless Y is sailing her proper course (RRS 23.2)

Between @1.8 and @2.2, Y touches the mark and decides to take a penalty.

Her proper course then, is to get well clear of other boats and promptly make her turn (RRS 44.2).

Y can promptly do this by, bearing away to starboard and gybing:  to continue changing course to port around the mark and past head to wind is not Y's proper course.

Assuming that @3-delta Y reached her close hauled course, and @3 is complying with her RRS 15 obligation to give G room to keep clear, G is changing course to keep clear of Y and Y is interfering with G, while Y is not sailing her proper course.

Y breaks RRS 23.3 and on valid protest should be penalised.

As noted above, 18 has turned off 18.1 b) and 18.1 a)4). Next, at 2, 11 applies. When Y tacks between 2 and 3, 13 applies. Assuming y completes her tack to S without requiring G to avoid, then 15 applies, initially. At that point 10 applies. I don’t see 23.2 applying here since the penalty turn for G happens long after Y and G are in conflict.

So, for the purposes of a hearing, if facts found that Y’s tack required G to avoid her before Y ended up on a close hauled S course, then Y breaks 13. If at the point that Y established a S close hauled course and G had to immediately avoid to keep clear, then Y breaks 15. Otherwise, no foul on Y or G, and G’s contact with the mark is unrelated and her taking a penalty turn exonerates her from breaking 31.

What’s missing in the diagram is what G had to do when Y tacked (eg between 2 and 3).

While Y was changing course from head to wind to a close hauled course G was not required to take any action to avoid Y, G was right-of-way boat (RRS 13).

was required to keep clear of Y immediately Y reached her close hauled course (RRS 10).  She was initially entitled to room to keep clear (RRS 15), Y bore away and gave her that room.

Y broke no rule.

Just a quick reply on the use of "Proper Course" within this discussion...

Any assertion regarding Yellow's "proper course" is unsupported by the evidence and irrelevant unless a rule that expressly relies on the concept of proper course has first been shown to apply.

The Racing Rules of Sailing define a boat's proper course as the course she would sail to finish as soon as possible in the absence of the other boats referred to in the rule using the term. Proper course is therefore a factual determination, not an assumption. It depends on numerous variables, including wind strength, sea state, boat characteristics, sail trim, tactical decisions, and the intended method of rounding the mark. None of this information has been established in the facts presented.

There is no evidence to demonstrate what Yellow's proper course was before or after tacking. Any statement that Yellow did or did not sail her proper course is therefore speculative and cannot be relied upon as a finding of fact.

Furthermore, the rules governing this incident do not generally require a determination of Yellow's proper course. Rights and obligations arise from the applicable right-of-way and mark-room rules, including Rules 10, 13, 15, 16, 18.1, 18.2 and, if applicable, Rule 18.3. Unless it is first established that a rule requiring consideration of proper course is applicable, Yellow's proper course is legally irrelevant to the analysis.

Even if Rule 18.3 is argued to apply, the issue is not whether Yellow sailed her proper course, but whether she complied with the specific obligations imposed by that rule. Those obligations depend on objective facts, such as where Yellow completed her tack, whether Rule 18 still applied between the boats, and whether Green was required to sail above close-hauled as a consequence of Yellow's actions. They do not require speculation about the course Yellow might have chosen in the absence of Green.

Accordingly, any argument based on Yellow's proper course lacks both factual foundation and legal relevance unless the applicable rule has first been identified and the necessary factual evidence established. In the absence of such evidence, references to Yellow's proper course should not be relied upon when determining whether Yellow complied with the Racing Rules of Sailing.

Rene,  a quick reply on the use of "Proper Course" 

You raise quite a lot of points in your post.  I'll try to reply to them.
 
Any assertion regarding [a boat's] "proper course" is ... irrelevant unless a rule that expressly relies on the concept of proper course has first been shown to apply.

Firstly, I'm not sure what you mean by 'expressly relies on'.  I'll take it that you mean no more than 'expressly refers to'.

That would be, in addition to the Definition Proper Course itself, Definition Mark-room, RRS 17, RRS 18.1(a)(2), RRS 18.4, and RRS 23.2.

To consider any specific matter in a protest committee's deliberations, it is by no means necessary to 'show' that a certain rule applies.  Protest committees need to be prepared to consider all rules that may apply.

Furthermore, the rules governing this incident do not generally require a determination of Yellow's proper course. Rights and obligations arise from the applicable right-of-way and mark-room rules, including Rules 10, 13, 15, 16, 18.1, 18.2 

And also including RRS 23.2 which contains a proper course exception.

 
within this discussion ... Any assertion regarding Yellow's "proper course" is unsupported by the evidence 

When judges are discussing a written 'rules problem', by convention, they do not rely on any fact not stated in the problem, for example if there is no mention of contact, then it is taken that contact did not occur.  It is, however useful to make some assumptions for the sake of discussion, for example, in a diagram, that the wind is coming from the top of the page, or, as in this case, that the next mark is to windward.  Some of these assumptions will be stated, some just made and then left open to challenge by others participating in the discussion

Just as in a live protest hearing, judges will consider all the evidence available including diagrams, textual descriptions, images, and some 'notorious facts' ('notorious' being used in its proper meaning of well-known, not 'infamous'), like boats will normally sail close hauled at about 45 to 40 degrees to the wind.

I think it's a pretty fair assumption in this case that this is a normal W/L course and the next mark is to windward.  Anyone that wants to challenge this is welcome to do so, as Anthony did in post 21762.

The Racing Rules of Sailing define a boat's proper course as the course she would sail to finish as soon as possible in the absence of the other boats referred to in the rule using the term. Proper course is therefore a factual determination, not an assumption. It depends on numerous variables, including wind strength, sea state, boat characteristics, sail trim, tactical decisions, and the intended method of rounding the mark. None of this information has been established in the facts presented.

I think judges are perfectly entitled to assume that the situation is 'normal', until there is evidence to the contrary.

FWIW, an assertion that a boat is sailing her proper course would be a 'conclusion' rather than a fact found:  it involves reasoning and judgement, see  Case 104.


There is no evidence to demonstrate what Yellow's proper course was before or after tacking. Any statement that Yellow did or did not sail her proper course is therefore speculative and cannot be relied upon as a finding of fact.

A boat can have more than one proper course.  Where the next mark is to windward, her proper course may be to sail close hauled on either tack.  There may be times when a boat's proper course is to tack.

Unless it is first established that a rule requiring consideration of proper course is applicable, Yellow's proper course is legally irrelevant to the analysis.

It may be that Yellow's proper course is irrelevant to the conclusions and decisions, but it may be by no means irrelevant to the analysis.

And there's nothing 'legal' about a protest hearing or a discussion among judges.


Even if Rule 18.3 is argued to apply, the issue is not whether Yellow sailed her proper course, but whether she complied with the specific obligations imposed by that rule.

RRS 18.3 is an interesting proposition.

At an enormous stretch you could say, if there was justification like a shift or a puff, that the proper course of G at the mark is to tack, so RRS 18 is not switched off in its entirety by RRS 18.1(a)(2).

I think that once Y changes course to windward so that she is no longer sailing more than ninety degrees from the true wind, she is sailing away from the mark (increasing distance between her and the mark), so she is 'leaving' the mark, and RRS 18 is switched off by RRS 18.1(a)(3).

So RRS 18.3 does not apply.

Also

Y passes head to wind from port to starboard in the zone of a mark to be left to port.

RRS 18.3 says that RRS 18.2 does not apply between her and another boat on starboard tack that is fetching the mark.

A boat is fetching a mark when she is in a position to pass to windward of it and leave it on the required side without changing tack.

G is not in a position to pass to windward of the mark and leave it on the required side (port).

G is neither on starboard tack nor fetching the mark.  RRS 18.3 does not apply

Those obligations depend on objective facts, such as where Yellow completed her tack, whether Rule 18 still applied between the boats, and whether Green was required to sail above close-hauled as a consequence of Yellow's actions. They do not require speculation about the course Yellow might have chosen in the absence of Green.

Yes, even though RRS 18.3 does not apply, when it does it does not depend on proper course.

Accordingly, any argument based on Yellow's proper course lacks both factual foundation

I disagree, we have the diagram, the textual description, which in this context we should accept as evidence of facts, and some challengeable assumptions.

That's quite sufficient for our purposes of discussion.

 and legal relevance unless the applicable rule has first been identified

Yes, a potentially applicable rule should be identified, but for the purposes of discussion or protest committee deliberation, it does not need to be proved to be applicable.

Rules that are proved to be applicable and broken will be shown in the protest commitee's Conclusions, and of course, these must be supported by Facts Found. 

 and the necessary factual evidence established. In the absence of such evidence, references to Yellow's proper course should not be relied upon when determining whether Yellow complied with the Racing Rules of Sailing.

Ang said:  A boat tacking inside the zone into oncoming traffic is executing a dangerous and rule-risky maneuver.

 I seriously disagree with this as a general statement.

Any boat anywhere is perfectly entitled to manoeuvre so as to 'tactically embarrass' another boat, provided she complies with the rules, in particular, in this case RRS 15.

And there is nothing dangerous about sailing as long as boats keep clear and give room.

There are lots of types of boats where the diagrammed manoeuvre would be completely unproblematic.

I'm trying to envisage how this would look if these were, say Sydney 38s.

G is plodding along downwind, trailing, setting up for a routine port tack rounding.  She should be set up for a windward drop, maybe with the pole off, in which case she will have no problem gybing back after luffing to keep clear of Y, or maybe she will still have the pole up: if she leaves the pole up too long after the drop, she'll be in trouble.  Dropping the pole quickly and tacking the headsail over the pole requires people to know what and how to do it.  I think that is right on the cusp of 'competent but not expert', but maybe it's a little on the 'very competent' side.

Yea .. thinking of a line of 35' J105's as that's my world .. with oversized asyms and poles out ... spins coming down obscuring views .. and a line of boats following which are not tacking at the mark .. sending Green into a starboard boats broadside or a port's broadside ... leaving only a spin-out to avoid. 

Sure .. if there is plenty of space between boats .. nothing wrong with this maneuver.  

The larger the fleet .. they tighter the racing .. the larger the boats and the faster they are moving .. the more caution I think the situation deserves.

I know this isn't relevant to the question, but I agree with this analysis but take it one step further.  If it was a dipole boat, Blue's pole would be in the process of coming off at position 2.  When Yellow starts the tack, Blue jibes onto starboard and starts dousing the spinnaker on the port side, crosses in front of Yellow, then jibes back.  This sets up a faster rounding (wide to tight) for Blue. I also agree this would need a 'very competent' crew.

G was required to keep clear of Y immediately Y reached her close hauled course (RRS 10).  She was initially entitled to room to keep clear (RRS 15), Y bore away and gave her that room.

Y broke no rule

It’s the initially that gives trouble in interpreting RRS 15. Olafur’s description notes G heads up to avoid Y, but the diagram isn’t clear when between 2 and 3 that happens. I’d agree that it appears Y satisfies 15, but obviously the facts found in a protest would dictate that. From experience with an appeal many years ago, I learned that the initially in 15 turns off “immediately” after “initially”.

Right… take a gate mark where taking the favored gate and immediately tacking can gain you boat lengths. Sure, you risk conflict with other downwind boats but tactically it’s the sound racing move.

 I think that is right on the cusp of 'competent but not expert', but maybe it's a little on the 'very competent' side.

I see maneuvers like this every week in our Melges 24 fleet; they’ll almost always opt for this exact maneuver to do a Mexican drop, and often rounding with larger slower boats at the same mark. Are they all experts? Nope, but all certainly competent.

Roon is given if there is no contact unless contact was only avoided by an unseamanlike manoeuvre, breach of a rule or a miracle.

I agree.  IMO it all hinges on whether or not the tack is complete before the avoiding course change occurred ... and whether or not Case 50's standard is met. 
Created: Today 12:17
I had this exact issue in Arbitration.  I suggest you look at it the way I explained it to the competitors.  Look at it as if there is no mark there when making your judgement.  The interaction between the boats on different legs is independent of whether a mark is near them or not.
