Golf club with selected length to weight ratio

Abstract

A golf club can include a shaft and club head. The club can have a selected length to weight ratio based on the length of the shaft and the overall weight of the club. The club head can include one or more areas with selective removal of weight to lighten the club head and/or move weight around in the club head.

1 . A golf club comprising:
 an elongate shaft having a shaft length, the elongate shaft comprising a grip portion, the grip portion having a grip length;   a club head attached to a distal end of the elongate shaft;   wherein the golf club has a total club weight;   wherein the ratio of the shaft length to the total club weight is between approximately 0.170 inch/gram and 0.185 inch/gram.   
     
     
         2 . The golf club of  claim 1 , wherein the shaft length is between approximately 47 inches to 49 inches. 
     
     
         3 . The golf club of  claim 1 , wherein the grip length is between approximately 8.5 inches to 9.5 inches. 
     
     
         4 . The golf club of  claim 1 , wherein the total club weight is between approximately 265 grams and 275 grams. 
     
     
         5 . The golf club of  claim 1 , wherein the shaft length is approximately 48 inches, and the total club weight is approximately 269 grams. 
     
     
         6 . The golf club of  claim 1 , wherein the grip length is approximately 9 inches. 
     
     
         7 . The golf club of  claim 1 , wherein the shaft has a weight of approximately 50 grams. 
     
     
         8 . The golf club of  claim 1 , wherein the grip has a weight of approximately 24 grams. 
     
     
         9 . The golf club of  claim 1 , wherein the club head comprises a crown portion, a sole portion, and a ball striking portion, the crown portion, sole portion, and ball striking portion forming an interior volume within the club head;
 wherein sole portion comprises a wall having an interior surface facing the interior volume, the wall comprising a first wall section having a first wall thickness and a second wall section having a second wall thickness, the second wall thickness being less than the first wall thickness, wherein the interior surface remains uninterrupted, and generally smooth, across the first and second wall sections without rising along the second wall section.   
     
     
         10 . The golf club of  claim 1 , wherein the club head includes a ball striking portion having a geometric center point, the wherein the club head includes center of gravity of the club head is located approximately 1.83 mm in a first direction based on the geometric center point, approximately 37.4 mm in a second direction based on the geometric center point, and approximately −1.5 mm in a third direction based on the geometric center point.
