Stealth tail quad surfboard

Abstract

A tail section for a surfboard includes a substantially v-shaped notch or cutout intersecting substantially trailing edges formed between two points. Each of the substantially straight trailing edges extend to the arcuate side of the body of the surfboard.

1 . A surfboard comprising:
 a body portion formed to have side edges and to be substantially symmetrical about a longitudinal axis;
 said body portion having a contiguous front portion ahead of a transverse axis, a center section on either side of said transverse axis, and a tail section behind said transverse axis; 
 said tail section having a substantially V-shaped notch formed so that the point of said V-shaped section is located on said longitudinal axis; 
 said tail section having a trailing edge adjoining said substantially V-shaped section at a first end and a second end adjoining said side edge of the surfboard. 
   
   
   
       2 . The surfboard as defined in  claim 1  wherein:
 said first end of said trailing edge and said second end of said trailing edge are substantially equidistant from said transverse axis.   
   
   
       3 . The surfboard as defined in  claim 1  wherein:
 the distance from said first end of said trailing edge from said transverse axis is greater than the distance of said second end of said trailing edge from said transverse axis.   
   
   
       4 . The surfboard as defined in  claim 1  wherein:
 the distance from said first end of said trailing edge from said transverse axis is less than the distance of said second end of said trailing edge from said transverse axis.   
   
   
       5 . The surfboard as defined in  claim 1  further including a plurality of fins extending outwardly from said tail section. 
   
   
       6 . A substantially symmetrical tail portion for a surfboard comprising:
 a pair of substantially arcute sides positioned substantially equidistant from a line of symmetry passing through the substantially symmetrical tail portion;   each of said substantially arcute sides terminating in a substantially straight trailing edge;   said substantially straight trailing edge extending between said substantially arcuate sides and intersecting a substantially V-shaped cutout;   said substantially V-shaped cutout formed on the line of symmetry of the substantially symmetrical tail portion.   
   
   
       7 . The substantially symmetrical tail portion for a surfboard as defined in  claim 6  wherein the said substantially straight trailing edges from a substantially acute angle with said line of symmetry. 
   
   
       8 . The substantially symmetrical tail portion for a surfboard as defined in  claim 6  wherein said substantially straight trailing edges form a substantially right angle with said line of symmetry. 
   
   
       9 . The substantially symmetrical tail portion for a surfboard as defined in  claim 6  wherein the said substantially straight trailing edges form a substantially obtuse angle with said line of symmetry. 
   
   
       10 . The substantially symmetrical tail section as defined in  claim 6  further including a plurality of fins extending outwardly therefrom 
   
   
       11 . A method for increasing the perceived stability of a surfboard to a rider, said method comprising the steps of:
 forming a substantially V-shaped notch in the tail section of the surfboard about the line of symmetry of the surfboard;   forming a substantially straight trailing edge portion of the tail section of the surfboard on either side of and intersecting said substantially V-shaped notch.   
   
   
       12 . The method as defined in  claim 11  wherein said substantially straight trailing edges form a substantially acute angle with said line of symmetry. 
   
   
       13 . The method as defined in  claim 11  wherein said substantially straight trailing edges form a substantially right angle with said line of symmetry. 
   
   
       14 . The method as defined in  claim 11  wherein said substantially straight trailing edges form a substantially obtuse angle with said line of symmetry. 
   
   
       15 . The method as defined in  claim 11  further including the step of mounting a plurality of fins extending outwardly from said tail section of said surfboard. 
   
   
       16 . A substantially symmetrical surfboard having a pointed front section, a center section, a tail section and side edges or herein the improvement comprises;
 a substantially V-shaped notch aligned with axis of symmetry of the surfboard cut into the tail section of the surfboard;   substantially straight trailing edges formed on either side of said substantially straight trailing edge;   each of said substantially straight trailing edges forming a first point at the intersection of one of said trailing edges and with said substantially V-shaped notch and a second point at the intersection of one of said trailing edges with the side edge,   wherein substantially V-shaped notch provides for flexing of each side of the tail section of the surfboard.   
   
   
       17 . The substantially symmetrical surfboard as defined in  claim 16  wherein an extension of said substantially straight trailing edge forms an acute angle with said axis of symmetry 
   
   
       18 . The substantially symmetrical surfboard as defined in  claim 16  wherein as extension of said substantially straight trailing edge forms a substantially right angle with said axis of symmetry. 
   
   
       19 . The substantially symmetrical surfboard as defined in  claim 16  wherein an extension of said substantially straight trailing edge forms a substantially obtuse angle with said axis of symmetry 
   
   
       20 . The substantially symmetrical surfboard as defined in. Claim  16  further including a plurality of fins mounted to the tail section on either side of said substantially V-shaped notch.
