The ISAF report does mention that "alternative equipment" might be designated. Maybe that will be the Hobie 16. But probably only if the ISAF Youth Worlds is ever held in a country that does not have the primary equipment. Since the ISAF Youth Worlds is usually held in Europe, and since that is where the manufacturer of the SL16 is, I assume the factory will be providing boats for the Worlds there.

There is a rumor that the new boat will not be phased in until 2007, so maybe the Hobie 16 will be used in the meantime -- but probably still with spinnaker?
