The International Sailing Federation has approved the most recent updates of the Vaurien Class Rules. Among several editorial corrections, two significant changes were made. First, the jib may have two windows, without changing the total window area, so that jibs with many radial panels still allow sufficient visibility. Second, and more important, as of 2012, hulls, rudders and centreboards may be built using epoxy resin. This should lead to stronger and more durable equipment, while the increase in cost is expected to be small.
The changes are summarized here.
