Seeing as how we've got our pedant hats on, Y's obligation is not to 'avoid' G. It is to keep clear of G. But Y's proper course is not only the course necessary to keep clear of G: it is the course she would sail to best speed. Y could sail somewhat hotter than as illustrated so as to avoid turbulence from G (or indeed, to avoid tempting G to luff aggressively), and that would still be her proper course.

As yellow is going to windward of green in your example she is not subject to Rule 17 with regards to Green though. Green however can use rule 11 should she choose to make life difficult for Yellow (and possibly Blue).

[Pedant hat] Minor point, but it's "a course a boat would sail to finish as soon as possible in
the absence of the other boats referred to in the rule using the term...." So take this scenario below, and saying that 17 applies between yellow and blue. When determining yellow's proper course, we can "remove" blue and see what that does to yellow's course. But yellow's proper course is to avoid green, so even though she sails higher than before, she doesn't sail higher than her proper course, and doesn't break 17.

Point is, Proper Course is to finish 'as soon as possible' not 'in front of a competitor'. |

They could argue whatever they like, the definition of Proper Course is 'in the absence of other boats' so PW's actions are immaterial.

They could argue that, but I think they'd lose the protest.

But could they not argue that they would have gone high if Symmetric wasn't there if PW had sailed that course?

Agree with Ed. PL would not have done that if the Symmetric spinnaker boat was not there. PW was free to do as they pleased pretty much as long as they kept clear of the Symmetric boat and PL (so going high to create space and gybe is a good tactical call IMO given PL's mistake).
