| 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.

What is claimed is:
1. An arrow comprising:
- a shaft having a forward end, an oppositely disposed rearward end, and a central axis; and
- a plurality of axially elongated vanes mounted to said shaft contiguous said oppositely disposed rearward end, each vane of said plurality of axially elongated vanes having a planar portion having a terminal edge at one end tangentially attached to said shaft without wrapping around said shaft, each said vane further having an extended fin portion projecting from an opposite end of said planar portion in a direction away from said central axis of said shaft whereby each extended fin portion of said plurality of axially elongated vanes extends in the same direction without overhanging said shaft, the undersurface of said extended fin portion and a radially outer surface of said planar portion defining an air channel for channelling air flow along said undersurface whereby said air flow along said undersurface of said extended fin portion generates a rotating moment about said central axis of said shaft to provide increased rotation and stability to said shaft and thereby improve flight accuracy of said arrow.
