Claims25
A golf club head comprising:
- a head body comprising:
- a head interior bounded by:
- a head front portion;
- a head rear portion;
- a head heel portion;
- a head toe portion;
- a head top portion;
- and
- a head sole portion;
- and
- a hosel structure having a bore for receiving a golf club shaft, the bore having a hosel axis;
- a head center of gravity;
- a head horizontal axis extending through the head center of gravity, from the head heel portion to the head toe portion, and parallel to a ground plane when the golf club head is at an address position over the ground plane;
- a hosel moment of inertia about the hosel axis;
- and
- a horizontal moment of inertia about the head horizontal axis;
- wherein the horizontal moment of inertia is greater than or equal to 39% of the hosel moment of inertia.

- and
- a head sole portion;
- and
- a hosel structure having a bore for receiving a golf club shaft, the bore having a hosel axis;
- a head center of gravity;
- a head vertical axis extending through the head center of gravity, from the head top portion to the head sole portion, and perpendicular to a ground plane when the golf club head is at address over the ground plane;
- a hosel moment of inertia about the hosel axis;
- and
- a vertical moment of inertia about the head vertical axis;
- wherein the vertical moment of inertia is greater than or equal to 59% of the hosel moment of inertia.
14 more elements
A method for providing a golf club head, the method comprising:
- providing a head body comprising:
- a head interior bounded by:
- a head front portion;
- a head rear portion;
- a head heel portion;
- a head toe portion;
- a head top portion;
- and
- a head sole portion;
- and
- a hosel structure having a bore for receiving a golf club shaft, the bore having a hosel axis;
- and
- coupling the golf club shaft to the hosel structure;
- wherein:
- a head horizontal axis extends through a head center of gravity of the golf club head, from the head heel portion to the head toe portion, and parallel to a ground plane when the golf club head is at an address position over the ground plane;
- a head vertical axis extends through the head center of gravity, from the head top portion to the head sole portion, and perpendicular to the ground plane when the golf club head is at address over the ground plane;
- providing the head body comprises at least one of:
- establishing a horizontal moment of inertia about the head horizontal axis to be greater than or equal to 39% of a hosel moment of inertia about the hosel axis;
- or
- establishing a vertical moment of inertia about the head vertical axis to be greater than or equal to 59% of the hosel moment of inertia about the hosel axis.
