Like all Davis Windex wind indicators, the secret to the Windex 10 Sport Vane is in the sapphire jewel suspension bearing, large fin-low inertia vane, and easy-to-read, fully adjustable tacking tab system. Reflector tape on the vane and tacking tabs make Windex 10 Sport easy to see day and night. Windex vanes are sturdy and when installed properly, offer many years of use. They have been wind tunnel tested to wind speeds of 80 knots!
Windex 10 Sport has a 10 in. (25 cm) vane. Includes glass reinforced polycarbonate J-Base for side, top or front of mast mounting on most dinghies, smaller boats and sport boats. Stands just 9.25 in. (23.5 cm) tall and weighs 1.2 ounces (31 g). Replacement vane (sold separately) also available.
