The waters around Rockcliffe are excellent for boating and windsurfing for experienced sailors or beginners, or just for kids having fun paddleboarding and body surfing. Launch from the shore or use other public jetties nearby.
The Solway Yacht Club operate from Kippford which is just a mile around the coast. They have a well supported annual regatta and sailing week. Click on http://www.thesyc.com/
