Embodiments of the inventive vane do not significantly increase the weight of an arrow and/or create a high probability of clearance problems with bow components. The vane is approximately 3.997 inches long and 0.327 inches high including the base height. The vane fin is approximately 0.28 inches high. Some embodiments may have a length approximately 2.997 inches long. An advantage of some embodiments is that the vane may be applied to an arrow shaft in a helical fashion.
