Are you sure about this? I thought you just had to be a member of US Sailing. I'm interested since I'm taking the class in a couple of weeks.
The application requires the signature / recommendation of a "flag officer" of your home club.
In my case, it was CRAM. You need to belong to an organization that is a member of US SAILING. Scuttlebutt YC or Sailing Anarchy YC would probably work, although getting the signature on the form might be problematic.
