Claims20
A golf club head comprising:
- a head body comprising:
- a head front portion;
- a head rear portion;
- a head heel portion;
- a head toe portion;
- a head sole portion;
- a head top portion;
- and
- a hosel structure having a bore for receiving a golf club shaft, the bore having a hosel axis;
- a strikeface at the head front portion and comprising a face height and a strikeface centerpoint, the face height being between 33 mm and 71 mm and the strikeface centerpoint positioned at a midpoint of the face height;
- a head volume of the golf club head is approximately 420 cc to approximately 470 cc;
- a head weight of the golf club head is approximately 185 grams to approximately 225 grams;
- a head center of gravity;
- wherein:
- when the golf club head is at an address position over a ground plane:
- a head vertical axis extends through the head center of gravity and is orthogonal to the ground plane;
- and
- a head horizontal axis extends through the head center of gravity, and is orthogonal to the head vertical axis;
- a loft plane of the golf club head is tangent to the strikeface centerpoint;
- a front plane of the golf club head extends through the strikeface centerpoint, parallel to the hosel axis, and orthogonal to the ground plane;
- a head depth plane extends through the strikeface centerpoint, parallel to the head horizontal axis and perpendicular to the loft plane;
- a head CG depth of the head center of gravity is measured, parallel to the ground plane and orthogonal to the front plane, between:
- a second intersection point located at an intersection between the front plane and the ground plane;
- and
- a third intersection point located at an intersection between the head vertical axis and the ground plane;
- the head CG depth is approximately 28 mm to approximately 102 mm;
- the head body comprises a weight structure located towards the head sole portion and the head rear portion;
- a clock grid comprises at least:
- a 12 o'clock ray;
- a 3 o'clock ray;
- a 4 o'clock ray;
- a 5 o'clock ray;
- a 8 o'clock ray;
- and
- a 9 o'clock ray;
- when the golf club head is at the address position over the ground plane, from a bottom view of the golf club head, the 12 o'clock ray is aligned with the strikeface centerpoint and orthogonal to a front intersection line between the loft plane and the ground plane;
- the clock grid is centered along the 12 o'clock ray, at a midpoint between a front end of the head front portion and a rear end of the head rear portion;
- the 3 o'clock ray extends towards the head heel portion;
- the 9 o'clock ray extends towards the head toe portion;
- a perimeter of the weight structure is at least partially bounded between the 4 o'clock ray and the 9 o'clock ray;
- and
- a center of gravity of the weight structure is located between the 5 o'clock ray and the 8 o'clock ray.
