Golf club head with vertical center of gravity adjustment

A wood-type golf club head comprising:

• a body comprising a face 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 crown, wherein the body defines an interior cavity;
• wherein the head has a face center positioned on the face at an approximate geometric center of the face, the face center including an x-axis tangential to the face and generally parallel to the ground when the head is ideally positioned, a y-axis generally perpendicular to the x-axis and generally parallel to the ground when the head is ideally positioned, and a z-axis generally perpendicular to the x-axis and to the y-axis and generally perpendicular to the ground when the head is ideally positioned, the head having a center of gravity whose location can be defined relative to the x-axis, y-axis and z-axis;
• and
• a plurality of weight ports formed in the body, the plurality of weight ports being arranged on the body to selectively receive and retain one or more weights to vertically displace the center of gravity up to about 2.8 mm;
• wherein the plurality of weight ports includes first and second weight ports, and the first weight port is located proximate to the sole and the second weight port is located proximate to the crown.

• and
• a plurality of external weight ports formed in the body, the plurality of weight ports being arranged on the body to selectively receive and retain at least first and second weights at respective externally accessible first and second positions on the body, the first and second weights having a total weight mass and a separation distance between the first and second positions, wherein the club head has a total weight mass multiplied by the separation distance which is at least 500 g·mm and no greater than about 15,000 g·mm;
• wherein the crown has a crown areal weight between about 0.15 g/cm2 and about 0.45 g/cm2 over at least 50% of the surface area of the crown.

• and
• a plurality of weights, each having a mass ranging from about 1 g to about 18 g;
• a plurality of weight ports formed in the body to selectively receive and retain the plurality of weights;
• wherein the plurality of weights includes first and second weights, the first weight having a maximum weight mass and the second weight having a minimum weight mass, the first and second weights having a separation distance therebetween when retained in their respective weight ports, wherein the maximum weight mass minus the minimum weight mass multiplied by the separation distance is between about 7600 g·mm and about 14250 g·mm;
• wherein one or both of the first and second weights may be retained in their respective weight ports such that the center of gravity has a head origin z-axis coordinate between about −6 mm and about 1 mm.
