Pretty much it, but my hypothetical thinking was that their courses were a little more parallel so it felt a little less of a deviation 

It looks pretty obvious that P has to make a substantial change to avoid the obstruction on your diagram

Thank you Jim, that's exactly it. We have a lot of these obstructions, and a 45'yacht certainly does require a significant alteration of course, but I had never come across this scenario before.
Generally the port gybe boat would have realised he was getting into a difficult situation and avoided it. I think he was asleep rather than hatching a cunning plan.
Ps, how did you do the drawing?

I did the drawing from a blank page in a vector drawing package (Corel Draw).

Ah I see, thank you. I was trying to find a tool in the forum.
