Surfboard with split tail flex technology

Abstract

Systems and methods for implementing a device for surfing, such as in water sports in which a user is on a top side of the device, are described herein. One aspect of the subject matter described in the disclosure is a surfboard. The surfboard nay include a top side, a bottom side, a tail section, and a front section. The tail section may be divided into three sections by transverse cuts with a length that is smaller than the length of the surfboard. The tail section may include two outer sections, and a middle-inner section. The middle-inner section may include a greater flexibility relative to the two outer sections.

What is claimed is: 
     
         1 . A surfboard, comprising:
 a top side,   a bottom side,   a tail section, and a front section, wherein the tail section is divided into three sections by transverse cuts with a length that is smaller than the length of the surfboard, wherein the tail section comprises:
 two outer sections, and 
 a middle-inner section, wherein the middle-inner section comprises a greater flexibility relative to the two outer sections. 
   
     
     
         2 . The surfboard of  claim 1 , wherein the middle-inner section comprises a rubberized traction pad. 
     
     
         3 . The surfboard of  claim 1 , wherein the middle-inner section is constructed to move relative to the two outer sections. 
     
     
         4 . The surfboard of  claim 1 , wherein the middle-inner section is configured to return to an original position after relative displacement is applied. 
     
     
         5 . The surfboard of  claim 1 , wherein the middle-inner section comprises a greater width relative to the two outer sections. 
     
     
         6 . The surfboard of  claim 1 , wherein the transverse cuts do not cut completely through the surfboard. 
     
     
         7 . The surfboard of  claim 1 , wherein the transverse cuts are reinforced against a tear of the transverse cuts. 
     
     
         8 . The surfboard of  claim 7 , wherein surfaces forming an opening of the transverse cuts are overlaid by an epoxy. 
     
     
         9 . The surfboard of  claim 1 , wherein fins are attached to the bottom side at different locations along the surfboard. 
     
     
         10 . The surfboard of  claim 9 , wherein the fins comprise two side fins and one middle fin. 
     
     
         11 . The surfboard of  claim 1 , wherein a traction pad is disposed along the top side opposite the bottom side along which fins are disposed. 
     
     
         12 . The surfboard of  claim 1 , wherein surfboard comprises a material configured to float along a water's surface. 
     
     
         13 . A method, comprising:
 flexing downward a middle-inner section of a tail section of a surfboard, wherein the tail section is divided into three sections by transverse cuts with a length that is smaller than the length of the surfboard, and wherein the tail section comprise two outer sections that are less flexible than the inner-middle section; and   flexing upward the middle-inner section of the tail section of the surfboard, wherein the surfboard is floating on a water's surface.   
     
     
         14 . The method of  claim 13 , wherein the flexing downward is produced by applying a downward force to the middle-inner section. 
     
     
         15 . The method of  claim 13 , wherein the flexing upward is produced by releasing the middle-inner section from a downward force. 
     
     
         16 . The method of  claim 13 , wherein the middle-inner section is configured to oscillate between the flexing downward and the flexing upward. 
     
     
         17 . A method, comprising:
 creating a first transverse cut through a surfboard; and   creating a second transverse cut through the surfboard, wherein the first and second transverse cuts define a tail section of the surfboard with two outer sections that are less flexible than an inner-middle section, wherein the length of the first transverse cut and the second transverse cut is smaller than the length of the surfboard.   
     
     
         18 . The method of  claim 17 , wherein the first transverse cut defines a clearance between surfaces of about 0.1 millimeters to about 5 millimeters. 
     
     
         19 . The method of  claim 17 , wherein the first transverse cut extends from a point of origin to a point of exit at around ¼ of a length of the surfboard. 
     
     
         20 . The method of  claim 17 , wherein the point of exit is around 1/14 th  of the length of the surfboard from the very end of the surfboard.
