Claims23
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 strikeface centerpoint;
- a head volume measured in cc's and comprising a head volume magnitude greater than 420;
- a head center of gravity;
- and
- an optimization characteristic;
- 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 and parallel to the hosel axis;
- a head depth plane extends through the strikeface centerpoint, parallel to the head horizontal axis and perpendicular to the loft plane;
- a CG height axis extends through the head center of gravity and intersects the head depth plane perpendicularly at a first intersection point;
- a head CG height of the head center of gravity is measured, along the CG height axis, between the head center of gravity and the first intersection point;
- 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 optimization characteristic is defined by (a) the head volume magnitude added to (b) a ratio between the head CG depth divided by an absolute value of the head CG height;
- and
- the optimization characteristic is greater than or equal to 425.
