1. A golf club, comprising:
- a shaft;
a club head defining an interior cavity, a sole defining a bottom portion of the club head, a crown defining a top portion of the club head, a skirt portion defining a periphery of the club head between the sole and crown, a face defining a forward portion of the club head, and a hosel by which the shaft is attached to the club head;
a channel positioned in the sole of the club head and extending into the interior cavity of the club head, the channel extending substantially in a heel-to-toe direction and having a channel length and a channel width, the channel comprising a front channel wall, a rear channel wall, and an upper channel wall extending between the front and rear channel walls, with the upper channel wall comprising a curve defining an inner radius and an outer radius;
at least one weight having a weight mass between about 0.5 grams and about 20 grams, the at least one weight installed in the club head;
wherein the front wall of the channel and the rear wall of the channel define an included angle β
that is between about 10°
to about 30°
;
wherein the club head has;
a height less than about 45 mm;
a volume of between about 180 cm3 and about 210 cm3;
an above ground center-of-gravity location, Zup, less than about 18 mm; and
a center of gravity horizontally rearward of a center of the face less than about 30 mm.

Abstract
A golf club head includes a body defining an interior cavity. The body includes a sole positioned at a bottom portion of the golf club head, a crown positioned at a top portion, and a skirt positioned around a periphery between the sole and crown. The body has a forward portion and a rearward portion. The club head includes a face positioned at the forward portion of the body. The face defines a striking surface having an ideal impact location at a golf club head origin. Embodiments include club heads for a fairway wood that at least one of a high moment of inertia, a low center-of-gravity, a thin crown and a high coefficient of restitution.

14. A golf club head, comprising:
-
a body defining an interior cavity, a sole portion positioned at a bottom portion of the body, a crown portion positioned at a top portion of the body, and a skirt portion positioned around a periphery of the body between the sole and crown, the body also having a forward portion and a rearward portion; and a face positioned at the forward portion of the body; wherein the golf club head has an above ground center-of-gravity location, Zup, less than about 18.5 mm; and wherein a center of gravity of the body is horizontally rearward of a center of the face less than about 30 mm; and wherein the golf club head has a coefficient of restitution (COR) having a value of at least about 0.80 as measured at three locations including a first location at a center of the club face and two locations spaced by 7.5 mm on either side of the center of the club face along a horizontal axis passing through the center of the club face. - View Dependent Claims (15, 16, 17, 18, 19, 20)
