Go to The Boat House in the old Waccamaw Pottery area by the waterway on Sunday. Live concert and a big raft up there every Sunday afternoon so far this summer. Not many performance boats in Myrtle Beach area, nor many places to watch, and aside from what Sean said in previous post, I'm not aware of any boater hangouts. There are lots of restaurants along the waterway from Little River to Barefoot Landing. Poos in Little River is a good place to sit and watch also.
