Go to the top of this forum and click on 'Sunfish Class'. That will take you to the 'International Sunfish Class' site, where you will find mention of major (National) regattas. Near the top of that page is a link to 'Nathional Class Associations'. Open this and click on 'United States Sunfish Class Association'. This will bring up a page that is outdated, but near the bottom is a box that contains links to regional associations. Many of these have a listing of the major events in their area. Good hunting and happy sailing.
