“Flying” Water Skis Ride On Hydrofoils
Tiny hydrofoil wings attached to these skis enable the skier to bank, dip, climb, and glide at speeds up to 35 miles per hour. The foils start lifting at eight miles per hour, ride two feet above the water.
CosmoDynamics Inc., Newton Upper Falls, Massachusetts, developed Dynaflite hydrofoils. Under the skis are a stabilizer and two “flying” wings, one of them removable for extra speed. A skier, it’s claimed, can learn to use the foils in a half-hour.
