A vane for guiding and stabilizing the flight of an arrow through the air after being released from a bow or crossbow provided with a string, the string of which bow or crossbow, at the time of release, is in engagement with the rear end of the arrow, said vane having an elongated and substantially planar body comprising:
a foot having a sufficient transversal width to provide a base for mounting of the vane on the arrow shaft, such that said elongated body has its longitudinal extension in the axial direction of the arrow shaft; a plurality of outer vane portions extending radially in the plane of said elongated body; and an inner vane portion connecting the foot and said outer vane portions, wherein, between two neighbouring outer vane portions, a valley, having a rounded shape at the bottom thereof, is formed by said two outer vane portions and the inner vane portion, wherein the bottom of the deepest valleys is located at a height of 17-30% of the total height of the vane. |
