Efficiently track apparent wind angle with the Small Allen Aerovane, ideal for dinghies. This mast head-mounted Aerovane is equipped with a built-in counterweight to prevent "flapping" in strong winds and ensure accurate readings. Its streamlined design minimizes drag while providing clear visibility of wind direction. Easily attach the Aerovane to your mast by pushing it firmly onto the rod until you hear a click, and remove it by pulling with force. The A4066 - Burgee clip (not included) is also required for top of mast installation. Replacement Aerovanes available separately.
