The pilot reported he was departing to the east with a five-knot tailwind in a float-equipped airplane. During the takeoff run, he realized it would not become airborne before reaching the departure end of the lake, and he closed the engine throttle in an attempt to abort the takeoff. The airplanes floats struck the shoreline and the airplane came to rest on the shore, about 75 yards from the lake, sustaining substantial damage to the right wing. The pilot indicated that there were no pre-accident mechanical problems with the airplane.
