An excerpt from the rule changes:
(You can read the whole NOR here: Extreme Sailing Series NoR 2011-blog.pdf)
1.7 ISAF has been requested to authorise the following changes under RRS 86. 2:
1.7.1 No national authority prescriptions will apply;
1.7.2 ISAF Addendum Q, Umpired Fleet Racing (Medal racing), ISAF Appendix Q, Umpired Fleet Racing (for a series of races), ISAF RRS Appendix C, Match Racing Rules, or Addendum F (a combined set of umpired fleet and match race rules) will apply for umpired races as modified by the Series Sailing Instructions and Regatta Sailing Instructions; and
(MUST remember, MUST remember, also in MATCH RACING!, always THREE!)18.104.22.168 RRS C2.3 is changed to read:
In the definition Zone the distance is changed to three hull lengths.
(This is straight from App. C (Match Racing) and has been implemented for several years already)22.214.171.124 RRS 18.3 Tacking when approaching a mark will be changed to read:
If two boats were on opposite tacks and one of them changes tack and as a result is subject to rule 13.1 in the zone when the other is fetching the mark, rule 18.2 does not thereafter apply. If, once the boat that changed tack has completed her tack,
(a) the other boat cannot by luffing avoid becoming overlapped inside her, she is entitled to mark-room, the boat that changed tack shall keep clear and rule 15 does not apply;
(b) the other boat can by luffing avoid becoming overlapped inside her, the boat that changed tack is entitled to mark-room.
(Now this change is because we had so much trouble last year with this issue!)126.96.36.199 When rule 20 applies, applies, the following arm signals by the helmsman are required in addition to the hails:
(a) for ‘Room to tack’, repeatedly and clearly pointing to windward; and
(b) for ‘You tack’, repeatedly and clearly pointing at the other boat and waving the arm to windward.
(Finally, they also have to avoid US, if possible)188.8.131.52 Rule 23.1 is changed to ‘If reasonably possible, a boat not racing shall not interfere with a boat that is racing or an umpire boat.’
(Did you notice what has been left out?. Makes it a little easier, if they can't, they can't and don't have to)184.108.40.206 Rule 18.2(e) is changed to ‘If a boat obtained an inside overlap from clear astern and, from the time the overlap began, the outside boat has been unable to give mark-room, she is not required to give it.’
220.127.116.11 Rule 13 is changed to
(Again from App. C> but now all the time, in all the races)13 WHILE TACKING OR GYBING
13.1 After a boat passes head to wind, she shall keep clear of other boats until she is on a close-hauled course.
13.2 After the foot of the mainsail of a boat sailing downwind crosses the centreline she shall keep clear of other boats until her mainsail has filled.
13.3 While rule 13.1 or 13.2 applies, rules 10, 11 and 12 do not. However, if two boats are subject to rule 13.1 or 13.2 at the same time, the one on the other’s port side or the one astern shall keep clear.
(How is that again? What don't the people watching understand? They do not understand P and Class flags nor no 2 and 3 minute signals? Right! We will now use coloured flags (PINK even) with 18.104.22.168.1.Start... Any 'ing M can understand THAT!)22.214.171.124 RRS Race Signals and RRS 26 are changed. Signals and start sequence timing will be defined in the SSIs/RSIs.
