Gate Starts - Proper Course

This has been bothering me for a while and I would appreciate the thoughts of others on the subject.

At a normal line start a very commom tactic is for a boat to establish and overlap to leeward and from clear astern of a boat or group of boats and then to luff slowly. This has the effect of forcing the windward boats to respond unde rule 11 disrupting their own starting tactics and creating a space to leeward of the luffing boat that she can accelerate into when the starting signal is made. As long as the leeward boat luffs slowly she does not break rule 16.1. Rule 17 applies to the overlap that she creates (if within two hull lengths) but because there is no proper course before the starting signal (see definition) she does not break it and as long as she bears away as soon as the starting signal is made no rule is broken.

At gate starts boats frequently adopt the same tactic as the path finder and gate boat approaches for the same reasons. The leeward boat creates space she can accelerate into and pass the stern of the gate boat travelling at speed. The problem as I see it is that the starting signal for the race was made when the gate was opened and the path finder started to sail her port tack. It follows that in these circumstances not only does rule 17 apply to the leeward boat but that she has a proper course as the starting signal has been made

My question is what is the proper course of the leeward boat in those circumstances? The definition says that it is the course she would sail in the absence of the windward boats to finish as soon as possible. Does this mean that L has to sail directly to the nearest point of the opening line which is of course moving ?. Can L argue that she is simply luffing to slow down as the path finder approaches and make a timely start? Does this come down to the motivation of L, if she luffs to slow down it's ok but if she luffs to affect windward boats she breaks rule 17 notwithstanding that the effect of the two different motivations may be the same? 

I am interested in the views of others on this as I struggle to get a clear and consistant set of "rules" clear in my head to apply to that situation.

I too would be interested in hearing what others think as I do not think the answer is black and white, unless there is a case somewhere.
I think the gate start as you call it is also what others refer to as a rabbit start. If I'm wrong, sorry. Anyways, if I'm right, in a square course starting anywhere along the path would leave everyone even.
 
That being said, after the gun, it's not every leeward boat's proper course to get to the gate boat (GB) ASAP. I'd make a stab at saying the proper course is to make a course that will allow her to duck the GB close at full speed, close hauled, and with space to leeward so they do not get affected by leeward boats. In order to create that space she might have to luff more than she would in a normal start and maybe even have to jibe after luffing to be in the right position. If she were to break rule 17 I think it would only be more clear once the gate boat approaches. If the path finder has/would have a poor start because she was luffing so much then she broke the rule. If she has/would have a good start then she doesn't, unless you could clearly show that proper course would had been to start earlier along the GB's course (eg. big shift).

Rule provides that a boat shall not sail above her while the rule applies.  A boat's is the course a boat would sail to  as soon as possible in the absence of the other boats. Thus, luffing to facilitate starting would be a boat's proper course.  Luffing to affect another boat is not.  Determining a boat's motivation in changing course does not change the rule.  It is up to the jury to make a decision as to what they believe the boat was trying to accomplish should the question be brought to them in a protest.  But a competitor should understand that they can't luff another boat during a gate start when rule 17 applies unless they would take the same action if the windward boat were not there.

I believe that the SIs may name the rabbit an obtruction (see Definitions) in which case an inside overlapped boat is entitled to room under19.2(a).

I am not sure how the"rabbit" system works. Under a gate start a port tack boat (the pathfinder) sails a long tack followed by a rib acting as gate boat which is the starting mark. Boats have to start between the start mark which the pathfinder sailed past when the starting signal was made which is one end of the line and the stern of the gate boat which is the other.

The definition of Obstruction makes it clear that SIs can't designate an object as an obstruction. An object either meets the definition of obstruction and is one or doesn't and isn't. The SIs can only designate an area as an obstruction, not an object. The pathfinder can't be an obstruction as the definition says that can only be the case if she is a boat that the others have to keep clear of which as a port tacker she isn't. As the gate boat is a starting mark surrounded by navigable water no part of Section C applies so no boat can claim mark room under rule 18 or room under rule 19 on the gate boat.
