Grant/Tony,
There have been very few occasions where ISAF/IYRU have been asked
for a rule interpretation in recent years (last 29 that I know of !!).
Two that spring to mind are 1) Definition of allowable rudder fittings -i.e.
was a rudder box included ?.
2) Legality of asymmetric racks .
Both of which I was involved in resolving. On both occasions IYRU/ISAF
were approached - via Tony Watts, ISAF Chief Measurer - and due to time
constraints only an unofficial opinion was given by T.W. which was accepted
by all concerned.
1) A rudder box was not allowable for weight purposes as a rudder
fitting.
The wording of the rule was subsequently altered to avoid confusion.
2). Asymmetric racks were not allowed ,as ISAF defined the beam
measurement to be centred about the middle - i.e. centreline - of the hull.
The rudder wings issue is the only time the class has gone to ISAF for an
"Official" interpretation. The difference on this issue has been the
widespread disagreement within the class over the wording of the relevant
rule.
Whilst the class does not use ISAF sail measurement definitions - this is
historic and there is now no good reason for this to continue - it does
accept , by not excluding ,ISAF hull definitions.
Although we are an International Class under the auspices of ISAF, the
class values its independence and as such has tended over the years to have
a consensus of opinion, within the class, over measurement/rule
interpretation matters and only used the offices of ISAF very sparingly.
I hope this clears things up.
Regards,
Rollo Pyper.

<p>I had this same idea a few years ago and asked the then president of the WA
Tom Treveleyan if there was an interpretation from ISAF on this matter. It
turned out that ISAF had declared that the 1/2 width be no more than 915mm
effectively stopping this arrangement. There has been some discussion on how
to get all the various ISAF interpretations that have been handed down over
the years into a format that can be accessed by owners. I think Colin Smith
was going to talk to Tom in the first instance to see if they were all
available in one place on paper to start with but I'm not sure about that.
Cheers
