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 of between about 0.8 mm and about 1.2 mm and an outer radius of between about 1.5 mm and about 2.5 mm;
a weight port positioned in the sole of the club head rearward of and adjacent to the channel, the weight port extending into the interior cavity of the club head;
at least one weight having a weight mass between about 0.5 grams and about 20 grams, the at least one weight configured to be installed at least partially within the weight port positioned in the sole of 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.
