This could be disastrous for PL if she was on the lay line prior to S turning up.
By ducking and giving room for PW to duck, PL has placed herself in an impossible situation at the mark.
In this scenario PL will want to call PW to tack under R20 but PW will want PL to duck under R19.

Who gets to make the call and why?

Alex covered this. If stbd is an obstruction for pl then pl chooses whether to tack or duck. But if she elects to duck she must give room for pw to duck too. If she wants to tack she must call early enough for W to respond, and if she does hail she cannot change her mind and duck instead.

Basically L decides which side she will go but w is always allowed to make the same choice as L.

Come on Tom, this is a pretty fundamental rule. If you don't give room, and the alternative is spearing an utterly innocent starboard tack boat then you're going to get a long sharp bow where it will quite spoil your day, and then a thankfully short protest meeting in which you'll get a DSQ while being unable to sit down.


I will make sure there is enough room for me to duck the Starboard boat but I would squeeze you to windward early, you then have the nice easy option of just tacking away or slowing down and waiting. Simple. Lets just get this straight, I imagine it's like the diagram below?

If I was PL, I would not allow PW any room to pass a Starboard tack boat, that's their problem not mine. Especially if I'm making that gap between the two Stb boats. (which I am)

Then you're going to be disqualified Tom, and if there's a collision and damage you're going to be paying for it.


19.2 Giving Room at an Obstruction
(a) A right-of-way boat may choose to pass an obstruction on either side.
(b) When boats are overlapped, the outside boat shall give the inside boat room between her and the obstruction, unless she has been unable to do so from the time the overlap began.

20.1 Hailing
When approaching an obstruction, a boat may hail for room to tack and avoid a boat on the same tack. However, she shall not hail if
(a) she can avoid the obstruction safely without making a substantial course change,
(b) she is sailing below close-hauled, or
...
20.2 Responding
(a) After a boat hails, she shall give the hailed boat time to respond.
(b) The hailed boat shall respond even if the hail breaks rule 20.1.
(c) The hailed boat shall respond either by tacking as soon as possible, or by immediately replying ‘You tack’ and then giving the hailing boat room to tack and avoid her.
(d) When the hailed boat responds, the hailing boat shall tack as soon as possible.
(e) From the time a boat hails until she has tacked and avoided the hailed boat, rule 18.2 does not apply between them.


And for a good example lets have Case 11.

CASE 11
Definition, Obstruction
Rule 14, Avoiding Contact
Rule 19.2(b), Room to Pass an Obstruction: Giving Room at an Obstruction
Rule 20.1, Room to Tack at an Obstruction: Hailing
Rule 21(a), Exoneration
When boats are overlapped at an obstruction, including an obstruction that is a right-of-way boat, the outside boat must give the inside boat room to pass between her and the obstruction.

Summary of the Facts
PW and PL, close-hauled on port tack and overlapped, approached S on the windward leg. PL could pass safely astern of S. PW, on a collision course with S, hailed PL for room to pass astern of S when PW and PL were about three hull lengths from S. PL ignored the hail and maintained her course. When PW bore away to avoid S, she and PL had slight beam-to-beam contact with no damage or injury. PW protested under rule 19.2(b).
The protest committee held that rule 19.2(b) did not apply, stating that PW could easily have tacked into the open water to windward to keep clear, and should have done so. PW was disqualified under rule 11 and appealed.

Decision
S was an obstruction to PW and PL because both PW and PL would need to change course substantially if they were sailing directly towards S and were one hull length from her, and because they both were required by rule 10 to keep clear of her (see the definition Obstruction). Under rule 19.2(a), PL, as the right-of-way boat, was entitled to pass S on either side.
She chose to pass to leeward of S. Therefore, under rule 19.2(b) PW was entitled to room to pass between PL and the stern of S. PL did not give PW that room, so PL broke rule 19.2(b). PL was subject to rule 14, but since she held right of way over PW and there was no damage or injury, she is exonerated for breaking that rule (see rule 14(b)).

PW could not have known that PL was not going to give sufficient room until she was committed to pass between S and PL. PW broke rule 11, but she did so while sailing within the room to which she was entitled by rule 19.2(b). Therefore, as required by rule 21(a), PW is exonerated for breaking rule 11. Also, when it became clear that PL was not giving room, it was not reasonably possible for PW to avoid the contact that occurred, so PW did not break rule 14.

PW was not required to ‘tack into open water to windward to keep clear’ because PL did not hail under rule 20.1 for room to tack and avoid S. Had PL hailed, PW would have been required by rules 20.2(b) and 20.2(c) to respond even though rule 20.1(a) prohibited PL from hailing because she did not have to make any change of course to avoid S.

PW’s appeal is upheld. The decision of the protest committee disqualifying PW is reversed. PW is reinstated, and PL is disqualified for breaking rule 19.2(b).

What a stupid rule, why should PL have to give up room to PW when PW shouldn't sail themselves in there in the first place? If PW slows down then they can sail astern of PL and clear the starboard boat, easy. It's just common sense isn't it?

All seems pretty basic to me. As far as I can recall, the rules have been like this for as long as I've been sailing, so 40 years or so,and never have I had an issue with it. Yes, you can (and i have)ended up with layline problems,but that just shows piss poor planning, really.

Its consistent with other rules. Its normal for inside overlapped boats to be allowed room to get through. The only exception I can think of right now is at start lines.

I have to say I would take a fair bit of convincing that your suggestion is in line with common sense, especially if you consider big thin leadmines that don't slow down very well.

For the same reason you can't sail people up the beach.
