The 2012 Olympic Legacy

Finn is not for lightweights is it, unless you count 95 kg light

alstorer - other way round, at least for the Finns:

Sailing instructions may NOT modify rule 42 (rule 86.1b) but Class rules may (86.1c)

Finn Class rules DO modify rule 42:

C.1.1 RULES
(1) RRS 42.3 is changed by adding a new RRS 42.3 (i):
42.3(i) The Race Committee may signal in accordance with RRS
Appendix P5 that pumping, rocking and ooching are permitted after
the starting signal, except when the boat’s proper course is closehauled
or above. This changes rules 42.2(a), 42.2(b) and 42.2(c).
(2) The Finn Class recommends that race committees apply Rule C.1.1 (1)
in winds of 10 knots and above, measured at deck level on a race
committee boat at the windward mark. See also A.7.2.

For the RS boats - Class rules may not modify rule 31 (rule 86.1c) but sailing instructions may (86.1b). A class may therefore suggest that when a club organises a RS race they modify the SIs. According to the rules it is the Race Committee who publish the SIs.It would be interesting to know if a club or race committee has ever refused!

Do you have examples of SIs  other than RS classes modifying rule 31.

Not surprising that I had not heard of this as none of these classes sai in Ireland, nor, indeed in France when I lived there.

I think that's covered in "that results in an advantage"- you could say that the manhandling results in an advantage in as much as it allows you to finish rather than be sat on your upturned boat whilst everyone curses you for making the mark harder to get round, but realistically you've gained a massive tiime pentlaty by cutting things so close to the mark, so no requirment to retire and no DSQ. I'd certainly hope that's what would happen if someone was petty enough to protest your misfortune
