Early season sailing, so my rules head is blunt.  I've also lost my handy book, which is really annoying! Angry!
 
Please excuse me if I ask some dumb questions!  I've just had a trawl through the old postings and assys thrown in the mix confused me.
 
The situation is - couple of port boats in the zone rounding the mark to port.  Water is being given by those boats and everything is civilised.  A late starboard boat approaches and enters the zone calling starboard. 
 
How should this now play out?  Ignore spinakers and anything more complicated, I just can't seem to get this straight in my head.  Do the port boats continue straight to the mark and round in the normal fashion or can the starboard gybe boat request room or other boats to gybe off to avoid him?
 
Thanks

the starboard boat almost certainly has rights to room at the mark- assuming all boats are sailing "angles".
They're ALSO right of way boat.

There are lots of "it depends" about this..
If the boats are sailing anything approaching hot angles the smart money is that starboard has been overlapped for a long time before reaching the zone so is owed water as well as being on starboard so port boats have to keep clear and if they need to gybe then that's tough...

But if starboard must gybe at the mark then they must do it promptly (18.4)

And if starboard was clear behind the port boats then 18.2.b overides 10 and starboard needs to let the port boats go if they are in the zone. If they are just outside the zone however its just port/starboard.

I see your point about the angles and determining overlaps.  However, I was sure that they arrived late and established the overlap once we were in the zone.  The speed difference was due to light airs and Darts v A-Class!
 
I did have nagging doubt about the situation as I did my turns.  I suspect that I had some rights under 18.2b as Jim said above, but it was a close call.
 
My homework for this week will be to refresh my rules head!
 
Thanks for the help.

The trouble is that as soon as opposite gybes are involved a boat can be a hell of a lot further from the mark than you are and still have an overlap...

Here's an extreme example: lets say the boats gybe through 90 degrees. The leader goes round the windward mark and bangs the R corner. All the other boats gybe off and bang the L corner. When the leader gybes the entire fleet, including boats that are hundreds of yards behind him, have an overlap. When he gets to the leeward mark all those boats will *still* be overlapped, so he needs to give room to any of them that are close enough to require it.

Thanks for the drawing, thats helped me get the picture straight in my mind.

Its too fine a line to call on whether I was clear of an overlap.  I guess the take home message for me it to not get caught in this situation again.  Useful lesson though - too often its all nice clean mark rounding.  I quite appreciate a nice problem to get your head around.  Just glad it was on a light wind day when everything goes that little bit slower

Were you both converging at 90 or so degrees?  If so it's almost vertain that there was an overlap a long way out!
