>where does it start? MYC? Hobie Beach? Anywhere?<
Most of the big boats are at MYC, and the beach cats can rig at MYC or Hobie Beach.

>How do you reach out to the non-racing sailors for this potential "Godzilla Floatilla?"<
There will be plenty of room on the big boats, any suggestions? Facebook?
I will be assigning big boat to beach cat via email.

I would like to get a bunch of beach cats to turn this into a regatta starting from Hobie Beach off Virginia Key.
I currently have five 30+ foot sailboats going, four from MYC, and six CABB beach catamarans.
a 42' & 49' cat condomarans, and a 31' trimaran.
