This smaller version of the Windex 15 has all the same features with a vane that is only 10 inches (25.4cm) long. Great for small boats or on big boats where 2 oz of weight saved aloft makes a difference! Weighs only 1.4 oz and stands just 9.25" tall. Can be equipped with Windex Light. Includes glass reinforced polycarbonate J-Base for side, top or front of mast mounting.
