Golf club head with low-drag hosel

A metal-wood type golf club head having improved aerodynamic properties, the golf club head comprising:

• a striking face;
• a sole connected to a bottom side of the striking face;
• a crown connected to a top side of the striking face;
• an asymmetric hosel extending from the crown at a heelward side of the golf club head, the hosel including a hosel opening configured to receive a golf club shaft defining a shaft axis, wherein the hosel comprises at least one tripping structure on an exterior of the hosel, an uppermost point at a height (HH), a midpoint at half the height (HH), and an exterior, wherein:
• at the midpoint, a frontmost point of the exterior of the hosel is a distance DHF1/2 from the shaft axis;
• and
• at the midpoint, a rearmost point of the exterior of the hosel is a distance DHR1/2 from the shaft axis, the distance DHR1/2 is 25%-70% greater than the distance DHF1/2;
• and
• an asymmetric ferrule coupled to the hosel, the ferrule having an exterior, an uppermost point at a height (HF) above the uppermost point of the hosel, and a lowermost point where the ferrule contacts the hosel, wherein:
• at the uppermost point of the ferrule, a frontmost point of the exterior of the ferrule is a distance DFFMIN from the shaft axis;
• and
• at the uppermost point of the ferrule, a rearmost point of the exterior of the ferrule is at a distance DFRMIN from the shaft axis, wherein the distance DFRMIN is less than 5% greater than the distance DFFMIN.

• wherein at the midpoint, a frontmost point of the exterior of the hosel is a distance DHF1/2 from the shaft axis as measured along an extension axis that intersects the shaft axis is offset from a front-to-back axis of the golf club head by 5-15 degrees;
• and at the midpoint, a rearmost point of the exterior of the hosel is a distance DHR1/2 from the shaft axis as measured along the extension axis, the distance DHR1/2 is 25%-70% greater than the distance DHF1/2, and
• wherein:
• at the uppermost point of the hosel, a frontmost point of the exterior of the hosel is a distance DHFMIN from the shaft axis measured along the extension axis, and at the uppermost point of the hosel, a rearmost point of the exterior of the hosel is a distance DHRMIN from the shaft axis measured along the extension axis, the distance DHRMIN being 5%-15% greater than the distance DHFMIN;
• or
• at a lowest point of the hosel where the hosel meets the crown, a frontmost point of the exterior of the hosel is a distance DHFMAX from the shaft axis measured along the extension axis, and at the lowest point of the hosel, a rearmost point of the exterior of the hosel is a distance DHRMAX from the shaft axis measured along the extension axis, the distance DHRMAX being 80%-120% greater than the DHFMAX distance.
