ABSTRACT:
An arrow having a shaft that has a forward end, an oppositely disposed rearward end, a central axis and a plurality of axially elongated vanes mounted to the shaft contiguous the oppositely disposed rearward end thereof. Each vane of the plurality of axially elongated vanes has a planar portion tangentially attached to the shaft and an extended fin portion projecting from the planar portion in a direction away from the central axis of the shaft. The undersurface of the extended fin portion defines an air channel for channelling air flow along the undersurface of the extended fin portion to generate a rotating moment about the central axis of the shaft to provide increased rotation and increased stability to the shaft and improve flight accuracy of the arrow.
