Rule 18 and Room at the Mark

When is a gate not a gate

This came up in the Soling Nationals--not as a protest but as a discussion following an interaction that was not protested.
The course had a leeward gate. The finish was a downwind "Dogleg" finish off the starboard bow of the signal boat (opposite side as the start line. The signal boat would be left to Starboard by boats finishing. The gate is specified as "2p" (left hand turn) or "2s," right hand turn. On the way to the downwind finish, the course chart specifies "...2p-F." So, you must leave the course-right gate to port and sail to the finish.
On the last downwind, two port tack boats are heading to pass between the gate and head to finish. A Starboard tack boat will need to gybe after leaving 2p to head to the finish. But, while on starboard, is on collision course with the Port boats. 

Rule 18.4 says:
"When an inside overlapped right-of-way boat must gybe at a mark to sail her proper course, until she gybes she shall sail not further from the mark than needed to sail that course.  Rule 18.4 does not apply at a gate mark."

Question 1: does rule 18.4 apply at this mark? It's called a gate mark in the SIs. But is it a gate in this case or just a single mark to be left to port? Bear in mind that we as judges are not supposed to do much interpretation: just apply the rule as written. So, while I might think the last sentence of 18.4 is there because Starboard could choose to sail to the 2s mark to round and is entitled to do so. But this is not the case here. So, it's not a gate on this leg. 
Or, should I say that it is defined as a gate in the SIs and therefore rule 18.4 does not apply and S can sail as far as she wants, forcing the port tack boats to gybe or take her stern.

The other level is how far could be considered proper course? The boats are not rounding to go back upwind. S could claim they wanted to sail a couple of BL farther to sail a hotter angle to the finish. That was their proper course. 

Thoughts?

Anthony,
The course 2P-F, indicates that it is not a gate. 2S is irrelevant and the SI normally indicates the course without including 2S in the description just before the Finish.

How does the same SI indicate the gate earlier?

Interesting dilemma.
Port tack running near 2p has a finite travel between the gate and the finish - mere inches, if close to the mark.
If she continues on port, she will basically be paralleling the finish line, and delaying her finish and the finishes of the starboard tackers.
18.4 does not apply.
But does Sportsmanship and Fair Play apply?
Case 78 tells us:
a boat may use tactics that clearly interfere with and hinder another boat's progress in the race, provided that, if she is protested under rule 2 for doing so, the protest committee finds that there was a reasonable chance of her tactics benefiting her final ranking
Now, what is her status the moment her bow crosses the finish line - which could be instantly.

I think the actual SI text is relevant: 8.3 The segment from the last gate to the finish line is part of the last downwind leg of the course.

I think they clearly mean that last gate is a gate and, for instance, you could not leave 2S to port.

If the course is “S-1-2s/2p-1-2p-F” then at this point in the race 2s is no longer affecting the course. 
If, on the other hand, the course was “S-1-2s/2p-1-2s/2p-F” you would be correct and a boat leaving 2s to port would be NSC.

Q1-does R18.4 apply
A1-yes, this is a mark, not a gate as clearly described in the SI as a course of “…2p-F.”
To test this, how would you score a boat that leaves both 2s (not a mark of the course on this leg) and 2p both to port then proceeds to the finish? The boat would correctly be scored her position and not “NSC” because 2s is not a mark of the course for this leg and does not affect her “string”. 
Q2-how far past 2p could be considered proper course for stbd?
A2-the proper course is the course stbd would sail in the absence of the other boats to finish as quickly as possible.

I'd like to ask about a similar, though not exactly the same, situation. Check out the attached ILCA Worlds sailing instructions. Note that the last turn, similar to the 2p to the finish, states "3s/3p". Also the course diagram shows the "string" going between both date marks. That means you must go between the two buoys. Does that make it a gate?

On one hand, you have to go between both buoys, which argues that this is a gate. On the other, sailors must turn in one direction (to port) after 3p, just like a leeward mark.

(How do I know that you have to go between both buoys? I learned the hard way. In one race, when I was in second, and it was blowing 20-30 knots with big waves, the only way I could rip off a jibe without capsizing was to round outside both 3s and 3 pm. I did so, thinking it was allowed, and my competitors behind me yelled to go back. Grateful they did; I dropped back to 6th, but better than a DNF.)

This use of the gate on the second downwind is because there is often more than one fleet using the outer leg. Eg One going to finish and one turning to go back upwind. The RC does not want boats approaching 3s from opposite directions.

This is a gate. Without the 3s in the course it is not a gate.

Below are the trapezoid courses of the most recent Princess Sofia regatta.   Unlike the ILCA trapezoids,  here mark 3s ( there is no gate) is no longer in play as the boat sail to the finish line.  I recall that during Perth 2011 we pulled the 3s mark.

None of the course diagrams above match the original question.

Here is a picture of the relevant section of the course. At the competitors meeting, the PRO was asked whether a boat had to pass between the gates on the way to the finish or could the leave both to port on the way to the finish.
With that information, the PRO is declaring that 2S is not a mark of the course on the last downwind.
This strongly favors the position that 18.4 would apply at 2P.

In looking at the SI for the event, there is an interesting, but probably minor, conflict in 8.3.

8. THE COURSE
8.1 The diagrams attached show the courses, including the approximate angle between legs, the order in which marks are to be passed and the side on which each mark is to be left. No later than the warning signal, the race committee signal boat will display the course number and the approximate compass bearing of the first leg.
8.2 Courses may only be shortened by eliminating the final lap. This changes RRS 32.
8.3 The segment from the last gate to the finish line is part of the last downwind leg of the course.
8.4 If one of the marks is missing at a leeward gate, the boats shall round the remaining mark to port. 

However, the course descriptions indicate that it is not a gate:
Course 2   Start – 1 – 1A – 2S/P – 1 – 1A – 2P – Finish
Course 3   Start – 1 – 1A – 2S/P – 1 – 1A – 2S/P – 1 – 1A – 2P - Finish

I think that if there was a protest over a boat not sailing through the gate, the conflict would be resolved in favor of it not being considered a gate.

The end result is that 18.4 would apply at 2P when boats are next headed to the finish.

Agreed… and SI 8.3 is completely superfluous and should probably just be removed.

I agree with you John. I was a bit confused by that conflict as well. The construction of the SI's was, I believe, a bit of a compromise.

The Olympics use this kind of finish on some of their downwind courses. See https://paris2024.sailing.org/racing/documents/. In their SI’s, 9.1 directs the reader to addendum C and D for the course diagram and mark rounding order/direction/etc. Reading these, it’s clear the last mark before the dog leg is just that, a mark, not a gate. If I had to write SI’s to include a dog leg, this is how I’d do it now.

I’d agree that SI 8.3 in the event in question here should be deleted.

Interesting that the ILCA Worlds wrote their SI’s that way as that course description clearly describes a gate. That said, I don’t believe the “strings” are strings per se for the purposes of RRS 28, but instead “direction arrows” (for lack of a better term) as visual aids. It’s the mark order and rounding direction that’s written that’s important.

Rule J2.1 (4) requires the sailing instructions to state the order in which marks are to be passed and the side on which each is to be left. 

Rule J2.1 (4) descriptions of marks, including starting and finishing marks, stating the order in which marks are to be passed and the side on which each is to be left and identifying all rounding marks (see the definition Sail the Course);

In the diagram below:
  1. Green touches mark 2s and passes it to port .
  2. Yellow is the inside right-of-way boat and must gybe at mark 2p to sail her proper course to finish. Yellow sails a few boat lengths past the mark, gybes, rounds the mark and leaves it astern.

The race committee has two courses A and B.
  • Course A   Start – 1 – 1A – 2p – Finish
  • Course B   Start – 1 – 1A – 2s/2p – Finish

If course A was signaled. Mark 2s is not a mark that begins, bounds or ends the leg of the course and can be touched and passed on either side. Mark 2p is not a gate mark. 
  • Green does not break a rule.
  • Yellow breaks rule 18.4. 

If course B was signaled. Mark 2s is a mark that begins, bounds or ends the leg of the course and cannot be touched and must passed to starboard. Rule 18.4 does not apply. Mark 2p is a gate mark.
  • Green breaks a rule 28.1 and rule 31.
  • Yellow does not break a rule.
