Built for the long haul, the Spoiler’s more rounded shape produces greater buoyancy and lower drag thanks to its ribbed design, which creates the turbulence required to lift the buoy from the water’s surface. The result is 82% less drag at 4.5 knots. Patented TRIValve allows for quick inflation without removing the valve while curved design prevents rope chafing. Bright, non-fading neon color delivers greater visability.
