Aquaplaning racers take to the water in a race off Juan-les-Pins.
Full title reads: "Thrills On The Waves. Aquaplaning at Juan-les-Pins".
Speedboats leave the edge of the water towing young men and women on boards / aquaplanes behind them. Various good shots as the speedboats and aquaplaners make their way around a course marked out with buoys. The sport looks like waterskiing using one large wide ski. Some of the riders show off their skills at stunts.
N.B. Item found in Unidentified Gazettes reel.
