     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     With reference now to the drawings, and in particular to FIGS. 1 to 9 thereof, a new and improved float tube anchor apparatus embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described. 
     More specifically, the float tube anchor apparatus 10 of the instant invention essentially comprises the positioning of a float tube 11, as indicated in FIG. 1, relative to a body of water, wherein a support cable 12 having a cable first end includes a first end hook member 13. The hook member 13 includes a spring plate 14 to form a closed loop in the biased communication of the spring plate relative to the hook member 13 permitting access within the enclosed loop upon displacement of the spring plate from the spring member 13, as the spring plate is anchored at one of its ends to the hook member base, as indicated in FIG. 2. A spool plate 15 is provided, having a central body plate portion 16, wherein a first end of the body plate 16 includes respective first and second parallel legs 17 and 18, with a second end of the body plate having third and fourth parallel legs 19 and 20. The second leg includes a second leg cable notch 18a, while the fourth leg includes a fourth leg cable notch 20a. As the cable is wound about the central body plate 16, the cable 12 adjacent the second and fourth cable notches 18a and 20a are directed into the cable notches for securement of the cable relative to the spool plate. A ballast weight 21 is mounted to the cable between the spool plate 15 and a support cable second end 22. The support cable second end 22 in turn is mounted to an anchor rod 23, or more specifically to the anchor rod guide loop 25 at a free distal end of the anchor rod 23, wherein a semi-spherical anchor dish 24 is secured at a remote end of the anchor rod 23 relative to the guide loop 25. In this manner, the anchor rod is coaxially mounted medially of the semi-spherical anchor dish 24, with the concave interior surface of the anchor dish 24 is a facing relationship relative to the guide loop 25. Accordingly, as the anchor dish is positioned upon a body of water bottom surface, as indicated in FIG. 1, engagement with that bottom surface is effected for use of the structure as an anchor, while a minimum of weight is required by the anchor permitting ease of transport of the anchor relative to the float tube 11. 
     The FIGS. 5-7 indicates the use of a secondary anchor portion including secondary anchor legs 27 fixedly mounted relative to one another in a fixed semi-cylindrical array about the anchor rod 23 defining a concave interior surface at a facing relationship relative to the guide loop 25, with the anchor legs 26 slidably mounted relative to the anchor rod 23 between the anchor dish 24 and the guide loop 25. An anchor spring 40 is captured between the anchor legs 26 and the anchor dish 24, wherein a latch button 27 is reciprocatably mounted within a latch button cavity 28 directed into the anchor rod 23, with a latch button spring 29 captured between the latch button 27 within the latch button cavity floor, whereupon displacement of the latch button 27 against the spring 29 displaces the latch button 27 within the latch button cavity 28 permitting the anchor spring 40 to displace the secondary anchor legs 26 in a spaced relationship relative to the anchor dish annular periphery 24a to provide for a secondary scooping and anchoring of the organization within a body of water bottom surface. 
     The FIGS. 8 and 9 indicate the use of a modified spool plate 15a, having modified spool plate first and second parallel legs 30 and 31 extending at a first end of the spool plate, with third and fourth legs 32 and 33 parallel to one another at a second end of the spool plate, wherein a first leg channel 34 and a third leg channel 35 are arranged in a parallel offset relationship relative to one another projecting beyond the first and second respective ends of the spool plate, with the first leg channel third leg channel having respective first and second channel slots 36 and 37 directed through the first and third legs in communication with the first and third leg channels 34 and 35 in a coextensive relationship. Respective first and second split sleeves 38 and 39 are rotatably mounted within respective first and second third leg channels 34 and 35, whereupon as the cable 12 is received within respective first and third leg channels 34 and 35, the first and second split sleeves 38 and 39 having respective first and second sleeve slots rotate the first and second sleeve slots in a displaced orientation relative to the first and second channel slots 36 and 37 to thereby position the cable 12 within the first and third leg channels 34 and 35 to insure capture of the cable wound about the spool plate central body plate 16, in a manner as indicated in FIG. 1. 
     As to the manner of usage and operation of the instant invention, the same should be apparent from the above disclosure, and accordingly no further discussion relative to the manner of usage and operation of the instant invention shall be provided. 
     With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention. 
     Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
