Poole inshore lifeboat launched at 11.30am to a report of a windsurfer hanging on to a catamaran in the North Channel, Poole Harbour.
The Poole lifeboat volunteers were soon on scene and found the windsurfer in difficulty hanging on to his kit in blustery conditions.
The lifeboat recovered the casualty from the water, checked that he was okay; he did not require any medical assistance.
The crew then de- rigged the windsurfer’s kit and took the casualty ashore at East Dorset Sailing Club.
The lifeboat returned to station and was ready for service at 12.15pm.
