Sting Ray Speed-XP Classic SR Hydrofoil

Speed-XP™ is a clear hydrophilic (water absorbing) material that is thermally, bounded to the base polymer material of the hydrofoil. The surface of this material is hard when dry and looks like a new wax job-however the magic of its performance is released when the surface becomes wet. Speed-XP™ acts like a microscopic sponge when wet and will bind a very thin layer of water to the surface of the hydrofoil. The result is running water on water. A dramatic reduction in hydrodynamic drag and improved performance.
