Room to clear a moving obstruction

   What if S now is required to tack?  For instance if he now needed to tack to cross the finish line.  Which is approximately placed at the bottom of the 'd' in 'Wind' in your diagram?
Is W relieved of his obligation to keep clear once S has tacked?

	Starting point as shown in diagram before S tacks, and supposing S is 1.5 hull lengths to downwind of the mark. While S is changing course towards the wind up until she is head to wind, she remains on starboard tack and both PW and PL are required to keep clear of her (rule 10), PW is required to keep clear of PL (rule 11) but PL is required to give PW room to pass between her and S (rule 19.2( b )). Once S passes head to wind she is subject to rule 13, rules 10, 11 and 12 do not apply, and S is required to keep clear of both PW and PL; all boats are now on the same tack, with at least S in the zone, so rule 18 applies: rule 18.2( b ) does not apply so rule 18.2( a ) applies and S, the inside overlapped boat is entitled to mark-room from both PW and PL, so if S breaks rule 13 while taking mark-room to which she is entitled she shall be exonerated; because PW and PL are no longer required to keep clear of S, S is no longer an obstruction (Definitions: Obstruction), rule 19 ceases to apply, but the mark-room PL is now required to give includes room for PW to give mark-room to S (Case 114). When S reaches her close hauled course on port, rule 13 ceases to apply and she will be to windward of PW and PL and required to keep clear of both of them (rule 11) but still entitled to mark-room.

	See updates to my previous post. S gets mark-room the instant she passes head to wind, which is the same instant she loses right of way and the same instant the obligation to give room to pass under rule 19 ceases to apply between PW and PL, and is replaced by the obligation to give room to give mark-room (Case 114). Which boat were you and what are the conclusions of the protest committee you want to appeal against?
