Important changes to class rules for 2009 European & World Championships

2009.06.10

Dear Moth Sailors,

As per the decision at the 2008 AGM, ISAF have now approved class rule changes in the following two areas, these rules are now in effect and thus will be valid for the 2009 European Championships in June and the 2009 World Championships in August.

The first rule change is that now boats that were first measured after 1 Jan 2005 can only carry sails measured to the new "true area" method.

Boats first measured prior to this date may continue to carry sails measured to the old method.

The second major rule change is that now it is legal to pump twice for each wave or gust or to promote foiling after each tack or gybe.

Repeated pumping as we have seen in some events is still illegal, as is any more than 2 pumps in an attempt to promote foiling in marginal conditions.

RRS 42 thus still applies and boats may be protested and/or disqualified for repeated pumping.

Regards,

Mark Robinson
IMCA President
