Springmaid Beach, Just south of Myrtle Beach proper, South Caroina. Nice parking lot to set up in, and a ramp over the dunes, it connects to the State park so its relatively sparse of people if you go south 100 yards from the ramp, and a good sailing spot. You can leave your boat on the beach or in the parking lot mast up. The only issue is when the boat is on the beach in the summer you have to leave your sails down so the lifegaurds can see.
