3. Heel Angle Sensor


Nke exclusive! This new electronic sensor measures a +/-70° heel angle with an accuracy of less than 2°. Heel angle recording is indeed essential to measure the boat’s performance, to constitute the polars and to regain its settings. Not taking the heel into account produces a 2.5° error on the angle of true wind and thus on its direction!
