If you are in Sydney I suggest you come down on Sunday and rig up with the rest of the fleet at either the SFS or WSC, that is usually the best approach. All boats are set up slightly differently.
Some general tuning info is on the International site here: http://www.sailfd.org/sails_fd_class_...
Any questions send me an email eghcox@16wardell.com.au or give me a call 0438 941 900.
