1. 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 two weight ports; and
at least one weight having a weight mass between about 10 grams and about 50 grams and configured to be installed at least partially within a weight port formed in the body;
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, 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 perpendicular to the x-axis and y-axis, and wherein an installed at least one weight has a head origin x-axis coordinate greater than about −
20 mm and less than about 20 mm, and wherein a golf club head center of gravity has a head origin y-axis coordinate greater than about 15 mm where the positive y-axis extends from the head origin inwardly toward the cavity, and wherein a volume of the golf club head is between about 180 cm3 and about 600 cm3.
