I agree with Jim...your proper course is 'in the absence of other boats'. Clearly the other boat affected your course therefore you did not sail your proper course.

Sorry, we know nothing of the kind.

Rule 17.2, which used to say that was deleted in the 2009 rewrite of the RRS.

Sorry about that..... I must have missed that  Cry

The way I've had it explained before is that it's not the other boat that affected you - you didn't alter course because of it's hull, or it's rig.  You altered course because the air getting to your sails was different, and the rules don't deal with differences in air, just the avoidance of collision. 

I'd be very interested to see any case studies that indicate this is wrong.

I'll turn that round.

I'd like to see any case studies or evidence that it could possibly be right. I see absolutely nothing in the rules that mention differences in air as opposed to avoidance of collision.

To me the definition is crystal clear: proper course is the course one would sail if the other boat wasn't there. To change it to "the course one would sail if the other boat wasn't there but nevertheless the effect it has on the wind is still there" seems, well, lets say distinctly odd.

I wonder if the interpretation you and Sargesail have heard goes back to the same person?

Obviously once they are clear ahead they can sail as high as they like but whilst overlapped their course should not change.

You were right before Jim - this needs an appeal - as written either of these interpretations could be correct.  An appeal would bring clarity.

I'm pleased to have sparked such an interesting discussion, and that maybe, just maybe, I mightn't owe anyone an apology. ;-)

I'm staggered it isn't already subject to a case study, but I couldn't find one.

The way I see it is that it is often difficult to say, especially in light winds, what is the effect of a wind change, and what the effect of a wind shadow from the other boat.  To expect a crew to differentiate between them and react only to the former is asking a lot in my opinion.  It is surely always a boat's proper course to come up and try to fill their kite when it collapses due to a lack of wind.

My own recent example isn't perhaps the best, as they'd driven us down past DDW and blanketed our kite.  But the protest committee certainly didn't react when I said I was trying to come up to fill the kite.

If you were clear ahead then you are well within your rights to do that. If you were still overlapped then you should not unless you can prove a significant shift that is unrelated to being blanketed or getting your dirty wind.

If you were allowing them to drive you further off the wind then you should have pushed them back up to your proper course (as the rules allow you to do as it is your proper course not their proper course that is important). If this was the case the the PC were right in not penalising you for that (IMO). This is as long as you gave them sufficient room to keep clear.

I certainly don't want to get into re-hearing the protest on a forum.  But it was very cut and dried with a GPS track to back it up.

I only brought it up because when I was asked if I had moved towards them I replied that if I had it had only been to try and fill my kite (which had collapsed) and at no point did anyone suggest that this would have been breaking 17 had I gone above my proper course with the other boat's wind shadow removed.  

As it was I was still well below that, as they'd driven down on us and tried to bully us into sailing low.  I was only below my proper course to avoid hitting them whilst we had a full and frank exchange of views on the subject!
