Title: Metal wood golf club head

Abstract: Disclosed is a metal wood club head with a body having a crown a sole, a skirt and a strike face. The sole has a first cavity located rearwards and towards the heel of the club head and a second cavity located rearwards towards the toe of the club head and approximately opposite of the first cavity. The two cavities define a relatively flat ridge or land area extending from the front of the sole rearwards which forms a beam-like stiffening structure. A backweight may be attached to the body portion to redistribute mass more rearwardly in the club head and directly behind the stiffening ridge. The redistribution of the mass rearwards increases the dynamic loft and moment of inertia of the club head and its position behind the stiffening ridge enhances energy transfer upon striking of a ball. The disclosed club head is thus provided with an increased moment of inertia to resist rotation and enhanced striking efficiency without an increase in club volume.
