I came across an iwindsurf map that showed launches that helped me to steer to the part of Sherman Island shown the post above this one. What I didn't realize is that the kiteboarders ride upwind of the windsurfers in sheltered waters in the lee of the two small islands. Thanks for the input Gabe. Segregation can be a good thing, at least when it comes to larger quantities of kiteboarders and windsurfers!
