Claim:
1. A dual-directional surfboard apparatus for use on the surface of a body of water and propelled by wave energy comprising: a first end; a second end such that either of said first end or said second end acts as a tail; a first end rail edge extending along first outer edge of said first end of said dual-directional surfboard; a second end rail edge extending along second outer edge of said second end of said dual-directional surfboard; a first side rail extending along a first outer edge of said dual-directional surfboard, wherein said first side rail is longer than either end rail; a second side rail extending along a second opposite outer edge of said dual-directional surfboard, wherein said second side rail is longer than either end rail; a latitudinal center Y-axis between said first end and said second end orthogonally bisecting said first side rail and said second side rail; a first latitudinal C-axis one third in from the said first end; a second latitudinal B-axis one third in from the said second end; a center longitudinal X-axis extending between said first side rail and said second side rail bisecting said first end rail edge and said second end rail edge; a top surface, such that a rider may be positioned on the top surface; a bottom surface such that it makes contact with water surface, wherein said bottom surface is planar extending between said first side rail and said second side rail parallel to said center Y-axis, wherein said dual-directional surfboard is configured to seat a plurality of fins such that said plurality of fins protrudes only from said bottom surface, wherein each of said plurality of fins protrudes orthogonally with respect to said bottom surface, wherein each of said fins running parallel with respect to said X-axis has a low profile elongated base length that is greater than said fins height measured from the said bottom surface of the surfboard to the tallest point of said fins, wherein each said elongated fin has a general linear surface along its chord length moving from the base of the said fin to the outer said fin tip edge, wherein each of said fins resides in a flow channel which directs the flow of water each having a length greater than its height; a equally divided three stage rocker curvature in the longitudinal contour of the said dual-directional surfboard defined by said B-axis and said C-axis comprising a center Area-Z, a first end Area-X, and a second end Area-Y, wherein said center sectional Area-Z is between said C-axis and said B-axis, wherein Area-Z is substantially neutral in respect to said three stage rocker curvature, wherein said Area-X and said Area-Y gradually deviates from said center Area-Z increasing in rocker curvature away from waters surface from said C-axis towards said first end and said B-axis towards said second end, wherein said Area-X and said Area-Y contain said low profile fins and said channels; a first directional orientation, wherein a rider has some foot contact with said top surface of said dual-directional surfboard, wherein said first end is the trailing back end and said second end is the leading front end established by forward motion relative between the said bottom surface and the water moving beneath it; a second directional orientation, wherein a rider has some foot contact with said top surface of said dual-directional surfboard, wherein said second end is the trailing back end and said first end is the leading front end established by forward motion relative between the said bottom surface and the water moving beneath it; a first contact section comprised of both said end Area-X and said middle Area-Z, wherein said first directional orientation is in use, wherein the said first contact section sits on and is engaged with the surface of the water, wherein the opposing said Area-Y is out of the water due to riders said first directional orientation and said Area-Y rocker curvature, wherein said Area-Y rocker and said low profile fins and said channels correlate in said rocker pitch and said fin height to reduce possibility of unintentional said fin interference with water surface; and a second opposing contact section comprised of both said end Area-Y and said middle Area-Z, wherein said second directional orientation is in use, wherein the said second contact section sits on and is engaged with the surface of the water, wherein the opposing said Area-X is out of the water due to riders said second directional orientation and said Area-X rocker curvature, wherein said Area-X rocker and said low profile fins and said channels correlate in said rocker pitch and said fin height to reduce possibility of unintentional said fin interference with water surface.
