Abstract:
A Nu-surf Surfboard introduces the surfing world to the “maxed out low deck” for lowest possible center of gravity surfing. It teaches “winged rails” for structure and other improved maneuvers and capabilities in combination with the maxed out low deck.

Description:
BACKGROUND OF THE INVENTION  
       [0001]    1. Field of the Invention 
         [0002]    The field of the present invention is a new surfboard that features a “maxed out low deck” and “winged rails”. Both features incorporated deserving the name Nu-surf. 
         [0003]    2. Background 
         [0004]    All surfboards up to the present have a top deck on which the surfer stands which is above a flotation space which is above the bottom that plains against the water. All surfboards have rails that connect the top deck rounding over to the bottom from nose to tail around the perimeter. The rails allow ocean water to flow off the top deck. The present invention moves the flotation space from under the surfer&#39;s feet towards and upwards to the side rails making new high winged rails. The surfer stands approximate the bottom which plains against the water. 
       SUMMARY OF THE INVENTION  
       [0005]    It is an object of the present invention to provide a surfboard where the surfer stands on the surfboard&#39;s lowest possible center of gravity. 
         [0006]    Another object of the invention is improved strength achieved from novel triangular constructed winged rails running nose to tail. 
         [0007]    Another object of the invention is new forward propulsion achieved by winged rails channeling ocean water towards the tail of the surfboard. 
         [0008]    Another object of the invention is to provide high winged rails that the surfer can better grab onto during many difficult surfing maneuvers. 
         [0009]    Another object of the invention is to provide the surfer with a short length embodiment of the invention so that surfers can use swim fins to assist paddling and by using the high winged rails to grab onto and lift oneself, providing ability to pivot swim fined feet under oneself when taking off on a wave. 
         [0010]    Still other important objects of the invention will become apparent from the discussion which follows.

     DESCRIPTION OF THE INVENTION  
       [0014]    Referring to the drawings  FIGS. 1 through 3  one form of the Nu-surf Surfboard is shown there. The surfboard is generally elongated having a nose  10  and a tail  11  end. The surfboard right and left side rails  6  connect the surfboard&#39;s top side  5  and the surfboard&#39;s bottom side  4 . 
         [0015]    The surfboard&#39;s bottom side  4  is generally flat,  FIG. 2 , extending from right rail  6  to left rail  6  and,  FIG. 3 , extending from tail  11  generally following rocker up to nose  10 . 
         [0016]    The surfboards top side  5  in the low deck area  13  which is generally under the surfer&#39;s feet “f” extending from the tail  11  is providing the surfer&#39;s feet “f” the lowest possible center of gravity position on which to stand and maneuver the surfboard. This is the first and most profound surfboard improvement. Profound to the extent it is like trying to maneuver a car going up hill (Nu-Surf) verses trying to maneuver a car going down hill. A surfer&#39;s feet “f” are positioned lower relative to the bottom  4 , the rails  6 , and the fin  12 . I have found that the Nu-surf Surfboard is much more responsive to the rails with respects to making turns when the surfer&#39;s platform  13  is below the rails  6 . That is one reason why it is like maneuvering a car going up hill verses down hill. 
         [0017]    Referring to  FIG. 2  and  FIG. 3 , the top side  5  gradually elevates and diverges from bottom  4  and low deck  13  over and up to highest point  7  of rails  6  and nose  10 .  FIG. 3  arrow  9  shows the direction that the winged rails  8  channel ocean water entering the top  5  area of the board. The highest point  7  along the winged rails  8  is where the surfer grabs the winged rails  8 . 
         [0018]      FIG. 2  clearly shows right and left winged rails  8  triangular construction, constructed with bottom  4 , top side  5 , and rail  6 .  FIG. 3  clearly shows these winged rails  8  running from nose  10  to tail  11 . 
         [0019]    There are additional uses for the winged rails  8  and their channeling effects  9 , besides making room for the surfer&#39;s maxed out low deck  13 , four of which I will discuss here. First, when paddling out through the surf a surfer will “duck dive” under the waves. Ocean water that comes over the top  5  of the board is channeled  9  by the winged rails  8  out the tail  11  and propels the board and surfer out. Next, when sitting waiting for a wave, the movement from sitting to prone pushes ocean water off the lower top  5  to tail  11  of the board propelling the board forward in front of the wave. Next, if the Nu-surf surfboard is made short enough such that the surfer&#39;s legs hang off the tail  11 , the surfer can use swim fins on feet “f” to paddle strong with legs and when catching the wave the surfer can grab the wing rails  8  at their highest point  7 , lift while paddling strong with feet “f” so that one can pivot the swim fins under oneself and stand up, all in one motion. This is a strategic maneuver especially in large waves. Fourthly, when in heavy soup when most boards become unstable, the surfer can grab the high winged rails  7  and let the ocean water channel to the tail and propel surfer forward. 
         [0020]      FIG. 1  and  FIG. 2  show a low profile stiffening and blunting means  14  that adds stiffness between right and left winged rails  8 , extending across low deck  13  in the area of the tail  11  and fin  12 . If the stiffening means  14  is a cavity  14  as shown, then it may also be used to blunt the sharp tail  11  end of low deck area  13 . 
         [0021]    Nu-surf Surfboards can be made using polyester or epoxy thermo set resins and fiberglass and use hand lay-up or mold tool techniques. The hand lay-up method may require shaped foam blank to hand lay-up onto. In such a case there may be one-half inch foam between low deck  13  and bottom  4 . It can also be made using thermoplastics such as polycarbonate or polyethylene and using thermo vacuum forming or rotational molding techniques. The low deck  13  and bottom  4  may be laminated together if the thermo vacuum forming method is used, whereas low deck  13  and bottom  4  may be formed coincident if the rotational molding method is used. 
         [0022]    Having now described the invention in detail in accordance with the requirements of the patent statutes, those skilled in this art will have no difficulty in making changes and modifications to the individual parts or their relative assembly in order to meet specific requirements or conditions. Such changes and modifications may be made without departing from the scope and spirit of the invention as set forth in the following claims.
