ABSTRACT:
For improvement in aerodynamic characteristics of a golf club head at swing, the transverse cross-section of the hosel is defined by a winged profile which includes at least one of a convex heel and concave toe sections. The sole face is defined by a convex sphere of a specified radius of curvature. The crown and sole faces are defined with vertical symmetry by respective convex spheres of similar radii of curvature. Current transition around the club head at swing is well prevented for higher head speed. Bias buoyancy at swing are minimized for a stabilized swing line.
