james, i beleive you can still launch from the beach access at Springmaid beach which is where OD ends. Last time i launched they made me leave my sails down, but I believe if you roll your boat south about 50 yards you will be good. This is where the lifegaurd stands end and Myrtle beach State park begins, pretty isolated there.
Downwind sails rents cats right near there and may let you leave your boat there. Downwind has a pretty cool store a couple of miles away, lots of Hobie stuff, diving, kite surfing, Mtn bikes, etc.

The men were amazed, and said, "What kind of a man is this, that even the winds and the sea obey Him?" Matthew 8:27
