The pilot reported that he began a right orbit off the shore of an island about 20 ft above the water. During the maneuver, the helicopter drifted and struck a tree leaning over the water. The helicopter subsequently lost altitude, impacted the water, and came to rest on its right side. The helicopter sustained substantial damage to the main rotor blades and fuselage. The pilot reported that there were no preaccident malfunctions or failures with the helicopter that would have precluded normal operation.
