1. Apparatus for resisting the crosswind effect on arrows provided with fletchings comprising:
- a number of pairs of fletchings spaced about a central shaft of the arrow, each of said pairs of fletchings having vertically rising surfaces having tips which are arched inwardly towards each other at the distal edges of the fletchings such that the fletchings are bowed inwardly to present minimal area to crosswinds while at the same time directing the flow of the crosswinds around the arrow.

Abstract
A molded aerodynamically crosswind resistant fletching includes pairs of spaced apart fletchings having distal edges bowed inwardly towards each other thus to deflect crosswinds over the tops of the fletchings.

10. A method for reducing the effect of crosswind on an arrow comprising the steps of:
providing the arrow with pairs of spaced apart fletchings, said fletchings oriented along the longitudinal axis of the arrow, with the inside surfaces of the opposed fletchings being bowed inwardly such that the distal edges of said fletchings are close together, the close together distal edges of the fletchings resulting in the directing of crosswinds about and around the fletchings as opposed to directly impacting the sides of said fletchings, thus to minimize rotational stall. - View Dependent Claims (11, 12)
