If you are a member of a local yacht club, or a local sailing club then you can declare your affiliation in the GO SAILING app. Simply go to your profile, scroll to the bottom, and click ADD CLUB. Then you can search for the club and add it to your list of affiliations.
When you are affiliated with a club you will see CLUB ONLY sailing events that have been created by other club members.
You will also be able to create your own CLUB ONLY events*.
