This is a continuation of a thread started by forum member Andrew Lesslie.  The original thread can be found here: Club race scenario, racing alongside a continuing obstruction

During that thread, Tim Hoffman offered a comparative scenario that we didn't really discuss.  What I have done below, is put both scenarios into one drawing so that the rule application differences can be examined more easily.

For all scenarios, assume that the proper course for all boats is to continue along the continuing obstruction.

Scenario #1: (quick summary from other thread)

1. Freeze Blue just before #3 (the point at which Green overlaps Blue), there IS NOT enough space for both Green and Yellow to progress forward in their relative positions
2. 19.3(c) applies and Green is not entitled to 19.2(b) room from Blue between Blue and the CO. 
3. Green must keep clear of Blue and rules 10 and 11 do not apply
4. Conclusion: Green, a boat which became overlapped from clear astern between Blue and a continuing obstruction while Green was not entitled to room under 19.2(b), failed to keep clear of Blue and broke rule 19.2(c).

1. Freeze Blue at #2 (the point at which Green overlaps Blue) there IS enough space for both Green and Yellow to progress forward in their relative positions
2. 19.3(c) does not apply and Green is entitled to 19.2(b) room from Blue between Blue and the CO. 
3. Green's room includes room for her to comply with Green's obligations under Part 2, which includes: 
   1. Green keeping clear of Yellow until just before #3, under rule 12
   2. Green giving Yellow 19.2(b) room between Green and the CO after Green becomes outside overlapped with Yellow at #3.
4. Conclusion:  Blue, the outside boat at an obstruction, failed to give Green room to pass the obstruction, despite being able to do so since the overlap began, and broke RRS 19.2(b) 

1. Between position 2 and 3, does the space Blue is providing Green satisfy Blue's requirements under 19.2(b)?
2. Does Green have any obligation to slow her boat to stay in that room?

PS:  There wasn't suggested wording for a Rule 19.2(c) conclusion, so I created a couple below.  What do you think of .. ?

Rev 1:

[Inside Boat], a boat which became overlapped from clear astern between [Outside Boat] and a continuing obstruction while [Inside Boat] was not entitled to room under 19.2(b), failed to keep clear of [Outside Boat] and broke rule 19.2(c).

[Inside Boat], a boat which became overlapped from clear astern between [Outside Boat] and a continuing obstruction, where [Inside Boat] was not entitled to room under 19.2(b) due to the lack of room for [Inside Boat] to pass between them at the moment the overlap began, failed to keep clear of [Outside Boat] and broke rule 19.2(c).

While passing a continuing obstruction, [Inside Boat], a boat which became overlapped from clear astern between [Outside Boat] and a continuing obstruction, where [Inside Boat] was not entitled to room under 19.2(b) due to the lack of room for [Inside Boat] to pass between them at the moment the overlap began, failed to keep clear of [Outside Boat] and broke rule 19.2(c).
