Patent ID: 7186190

Claim:
A wood-type golf club head comprising: a body comprising a face plate positioned at a forward portion of the golf club head, a sole positioned at a bottom portion of the golf club head, a crown positioned at a top portion of the golf club head and a skirt positioned around a periphery of the golf club head between the sole and the crown, wherein the body defines an interior cavity; at least first and second weight ports formed in the body; and at least a first weight having a mass between about 1 g and about 18 g configured to be retained at least partially within the first weight port and a second weight having a mass between about 1 g and about 18 g configured to be retained at least partially within the second weight port, wherein the at least first and second weights have a weights volume and a weights mass; wherein the head has a golf club head origin positioned on the face plate at an approximate geometric center of the face plate, the head origin including an x-axis tangential to the face plate and generally parallel to the ground when the head is ideally positioned and a y-axis generally perpendicular to the x-axis and generally parallel to the ground when the head is ideally positioned, and wherein the first weight has a head origin x-axis coordinate greater than about −52 mm and less than about −12 mm and a y-axis coordinate greater than about 36 mm and less than about 76 mm, and the second weight has a head origin x-axis coordinate greater than about 10 mm and less than about 50 mm and a y-axis coordinate greater than about 36 mm and less than about 76 mm, and wherein a golf club head center of gravity has a head origin x-axis coordinate greater than about −3 mm and less than about 8 mm and a head origin y-axis coordinate greater than about 30 mm and less than about 40 mm where a positive y-axis extends towards the cavity, and wherein the golf club head has a moment of inertia about a head center of gravity x-axis generally parallel to the origin x-axis between about 220 kg·mm 2 and about 360 kg·mm 2 and a moment of inertia about a head center of gravity z-axis generally perpendicular to ground when the head is ideally positioned between about 360 kg·mm 2 and about 500 kg·mm 2 , and wherein a volume of the golf club head is between about 400 cm 3 and about 500 cm 3 , and wherein a mass of the golf club head minus the weights mass is between about 180 g and about 215 g.
