Station 12 sullivan's island is where I sail from. I like it because it is on the inlet and you can go inside or outside. I have never sailed from Folly. There is no mast up storage at sta. 12. I do leave my boat there ocasionally over night if i am coming back the next day. she is sitting there now waiting for me to get off work. leaving the boat on the beach is at your risk but nothing has ever happened to my boat. the homeowners threatened me last year about leaving her there. Sta. 12 has the easiest access the pavement goes right to the beach and it is always clear since it is an emergency lane. Do not leave trailer in parking lot. Do not park on right. Do Not park in HAndicaped $250. Leave trailer on beach up by the grass. The police on Sullivan's are always patroling looking for someway to raise revenue. see yah out there. What do you sail? Also watch out for commercial traffic. It is amazing how fast those container ships move.
