BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates to the field of a transportable floating dock for personal watercraft such as one or more Jet Skis. 
   2. Description of the Prior Art 
   There are a group of highly maneuverable and relatively fast vessels, one of which is sold under the trademark Jet Ski, which can carry one or two persons standing or kneeling on a base. The user holds the handle, which pivots the nose of the Jet Ski. The handle has the Jet Ski&#39;s throttle. A user turns the Jet Ski by leaning in the direction of the turn. The center of gravity of a Jet Ski is relatively high. There is a significant need for a floating dock which allows the Jet Ski to be parked at the dock and is designed so that the Jet Ski with a relatively high center of gravity will not tip over. In general, the concept of a dock for a Jet Ski is known in the prior art.

   The Walters patent discloses a flotation collar which is placed around the hull of a boat to improve the stability of the boat. The invention provides a method for forming an inflated flotation around at least a part of the hull of a boat, which method comprises positioning a longitudinal inflatable member along at least a part of the length of both the port and starboard sides of the hull; securing the terminal portions of the member so that the linear length of the gunwale over which the member extends is substantially fixed and so that the member is held substantially at gunwale level on the hull by securing means passing around and optionally over but not under the hull; and inflating the inflatable member whereby the expansion of the member causes the member to bear against the hull against the restraining effect of the securing of the terminal portions. 
   The Klaus patent discloses a floating dock for a Jet Ski wherein only the nose portion of the Jet Ski and not the lengthwise sides are retained by the dock. Therefore, although retained by a floating dock, the retention is in an unstable manner because the majority of the Jet Ski floats freely in the water. It is therefore easy for the Jet Ski to tip over or break loose from the dock and float away. 
   The Culley patent discloses a modular floating environmental mooring system. It accommodates a plurality of boats at circumferentially spaced, radially extending positions relative to a central dock member. The invention relates to a modular environmental mooring system of star shaped configuration to accommodate a plurality of boats at circumferentially spaced, radially extending positions with respect to a central dock member. The central dock member is of generally annular configuration which includes a plurality of segments, each having a planar outwardly facing end wall and a pair of planar sidewalls lying in spaced apart angularly disposed planes. As a result, only the nose of th Jet Ski is retained and the sides of the Jet Ski are not retained by this star shaped pattern dock. 
   The Hillman patent is a design patent which protects the shape of a personal watercraft dock. While it does show a lengthwise sidewall as well as a nose retaining portion, there is nothing in the design which permits the sides of the Jet Ski to be firmly retained within the dock. 
   The Elson patent discloses a lift for docking, supporting and launching a personal watercraft having a rearwardly tapering bow portion into, on and from, respectively, a body of water comprising a shell defining a cradle for supporting the watercraft thereon and having an open end for horizontally docking and launching the watercraft from and into the body of water. 
   The Eva, III patent discloses a floating drive-on dry dock assembly. It is assembled from two kinds of hollow floatation units, tall units and short units. The units are interconnected so that their top surfaces are substantially coplanar. The units are arranged to form two arms which support the hull of the craft on each side of the longitudinal center line of the craft. The entire length of each arm is made up of tall units except the distal end portions of each arm which may be made up of short units. The short units are able to flex downward as the craft begins to ride up on the dock because of the location of the connection between the adjacent units. 
   The Gates patent discloses a portable marine outhaul. In particular, FIG. 1 shows a simplified schematic view of a boat 10 moored in a body of water 12 between a sea anchor 14 and a land anchor 15 secured on a shore 18. The boat is attached at Point 19 to a portable marine outhaul that includes a line 22 journaled at a sea end 22a on a pulley 21a attached both to float 13 and to sea anchor 14, and at a shore end 22b on a pulley 21b attached to land anchor 15. 
   The Lekhtman published patent application discloses the concept of interconnecting dock modules together to create various shapes. 
   Finally, the PCT Application discloses a floating dock. It discloses a method of dry docking vessels comprising a floating dock comprising a main ballast vessel (3), a load supporting raft (2), a load supporting raft (2) and a main ballast vessel (3) being selectively attachable to each other, the main ballast vessel (3) and the load supporting raft (2) having separately variable buoyancy. 
   There is a significant need for an improved floating docking system which can stabilely and securely retain at least one Jet Ski in the water. 
   SUMMARY OF THE INVENTION 
   The present invention is a docking system for personal watercraft such as a Jet Ski which docking system is moored to the shore by at least one stake which permit the dock to float several feet away from the shore. The present invention docking system has a shape which is conformed to the shape of the personal watercraft with the method of having a rolling means on a rope stretched across the entrance to the dock so that the dock itself is pulled adjacent the sides of the personal watercraft as it enters the slip so that the personal watercraft will not bang against other personal watercraft and is snugly retained within the dock. In an alternative embodiment of the present invention, the dock comprises an island which maintains a multiplicity of personal watercraft at 90 degrees to each other so that a multiplicity of personal watercraft can be moored at the same time and moored in a configuration so that they will not hit each other. 
   There are two variations of the present invention docking system for personal watercraft. The first variation is a device that floats close to shore so that the device itself is tethered by a stake that is in the shore and then attached by tether lines so that it floats about fifteen (15) feet off shore and further comprises one or more landing islands where the personal watercraft can be docked and tethered itself by a line that hooks to the front part of the personal watercraft. 
   The dock device is basically a flat, inflatable piece of synthetic material. By way of example, the two personal watercraft version can be 118 inches wide, have an overall length of 84 inches and a depth or height of 6 inches. It is an inflatable raft device made of PVC plastic or rubber that can be inflated so that it is buoyant. It is filled with low pressure gas such as air of approximately 7 or 8 psi. The dock is conformed to the shape of the personal watercraft so that it can accommodate the specific shape of the individual watercraft. The watercraft is either triangular or spear shaped so that it will be one size or one shape configuration for the docking. 
   In use, the device is tethered by one or more lines which are then affixed to a stake which is hammered into the shore surface such as sand or dirt. Then for each individual slip within the docking system, there is an embedded cord which is in the personal docking system and the cord has a hook at the end of it which hooks onto the front of the personal watercraft so that the personal watercraft can be retained in the floating island. 
   When the personal watercraft enters the slip, there is a rope that is stretched across the entrance with a roller on it so it keeps the rope submerged. This stretches across the lower widthwise portion of each slip. Then as the personal watercraft enters through the slip, the hull of the personal watercraft pushes down on the rope so it forces the sides of the slip together so that the personal watercraft is snugly fit inside the slip and is hooked at the front end of the personal watercraft by a hook at the end of a strap from the slip to anchor the personal watercraft therein. Therefore, the rope essentially has the ends of the opening of the slips tied together against the personal watercraft so it won&#39;t pull away. 
   It is therefore an object of the present invention to have a floating dock which has slips in the shape of a personal watercraft which can float offshore and is anchored to the shore by means of ropes which are affixed to a stake that is hammered into the shore surface such as sand or dirt. Each slip in the docking system has its own separate rope or cord which is made and incorporated into the slip and has a hook at the nose end of it which is hooked to the personal watercraft when it is moored in the slip. 
   It is a further object of the present invention to provide a submerged rope that stretches widthwise along the entrance to the slip so that the sides of the slip are pulled against the personal watercraft by means of the hull pulling on the submerged rope as it is pulled into the slip so that it is snugly fit within the slip and will not turn over and will not bump against an adjacent personal watercraft in an adjacent slip. 
   It is also an object of the present invention to provide an optional anchor bag on either side of the dock so that it will cause the dock to remain floating and not float away from the shore. Therefore, in addition to the strap or rope that anchors the floating dock to the shore, there are separate bags on either side of the floating dock so that it can be anchored to the location where it is floating and not float away. 
   It is an additional object of the present invention to provide mating or fastening means such as hooks or hook and loop fasteners on the sides of each dock so that a multiplicity of docks having two or three slips each can be attached together so that they form a long island of slips. 
   A second alternative embodiment of the present invention is to have a dock island which floats in the middle of a body of water such as a lake. Instead of being anchored close to a shore, the floating dock is anchored by having anchor bags located on at least two opposite sides and possibly all four sides of the floating dock, so that it will not float away. This dock also operates on the same principle in that there is a cord embedded into the dock with a hook at the end of the cord so that when the personal watercraft is placed in an individual slip in the float dock island, it is retained in placed by the hook. A key innovation in this variation is to have the slips facing at 90 degrees to each other so that the dock island can retain four separate personal watercraft which are positioned 90 degrees apart so that they will not bump into each other. A further innovation is to provide a canopy affixed to and positioned over the body of the dock island so that a person can sit on the dock island and sunbathe while the personal watercraft are anchored to the dock island. 
   It is therefore an additional object of the present invention to provide an alternative embodiment personal watercraft docking system where the docking system is a floating dock island having a body and four separate slips positioned 90 degrees to each other so that when two or more personal watercraft are retained in the dock island, adjacent personal watercraft will not bump against each other. 
   It is a further object of the present invention to provide a dock island having a body with a canopy positioned over the body and retained on the dock island so that a person can sit on the body and sunbathe while at least one personal watercraft is retained in a slip on the island. 
   It is another object of the present invention to provide a means for anchoring the dock island so that it will not float away. 
   Further novel features and other objects of the present invention will become apparent from the following detailed description, discussion and the appended claims, taken in conjunction with the drawings.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
   Although specific embodiments of the present invention will now be described with reference to the drawings, it should be understood that such embodiments are by way of example only and merely illustrative of but a small number of the many possible specific embodiments which can represent applications of the principles of the present invention. Various changes and modifications obvious to one skilled in the art to which the present invention pertains are deemed to be within the spirit, scope and contemplation of the present invention as further defined in the appended claims. 
   Referring to  FIGS. 1 ,  3 ,  5  through  12 , and  14  and  15  there is illustrated the first variation of the first alterative embodiment of the present invention which is a two slip docking system for personal watercraft. Referring specifically to  FIGS. 3 ,  8  through  12  and  15 , there is illustrated at  10  the two slip docking system. The two slip docking system  10  is an inflatable raft having an inflation/deflation valve  12  (see  FIG. 8 ) by which a gas such as air is forced into the interior of the raft so that it expands into a raft as best illustrated in  FIG. 15 . The dock  10  has two slips for receiving a personal watercraft, a first slip  14  and a second slip  14 A. Each slip is identical and aligned side by side and parallel to each other. First slip  14  has a circumferential sidewall  16  having a first arcuate side section  18  and a mirror image second arcuate side section  20  which converge in a nose section  22 . First slip  14  has an opening  24  which leads to an open space  26  between the arcuate side sections  18  and  20  into which a personal watercraft is received. Second slip  14 A has a circumferential sidewall  16 A having a first arcuate side section  18 A and a mirror image second arcuate side section  20 A which converge in a nose section  22 A. Second slip  14 A has an opening  24 A which leads to an open space  26 A between the arcuate side sections  18 A and  20 A into which a personal watercraft is received. 
   One key innovation of the present invention is the incorporation of a rope  28  supported on each arcuate side section  18  and  20  of first slip  14  at a location adjacent opening  24  so that the rope extends between the arcuate side sections. A weighted roller  30  is supported on the rope  28  so that the rope  28  is submerged in the water on which the dock  10  floats. When a personal watercraft  200  (see  FIGS. 1 ,  5 ,  7  and  14 ) is driven into or pulled into opening  24  within first slip  14 , the hull  202  of the personal watercraft  200  slides on the weighted roller  30  and serves to pull the arcuate side sections  18  and  20  toward the opposite sides of the hull  202  so that the hull  202  of the personal watercraft  200  fits snugly within the first slip  14  as best illustrated in  FIG. 14 . As a result, due to this snug fit of each arcuate section  18  and  20  of sidewall  16  being forced against the respective opposite sides of the hull  202 , the personal watercraft  200  is firmly retained within the first slip  14  so it will not tip over and will not bump against a personal watercraft moored in an adjacent slip  14 A. Similarly, a rope  28 A is supported on each arcuate side section  18 A and  20 A of second slip  14 A at a location adjacent opening  24 A so that the rope extends between the arcuate side sections. A weighted roller  30 A is supported on the rope  28 A so that the rope  28 A is submerged in the water on which the dock  10  floats. When a personal watercraft  220  (see  FIGS. 1 ,  5 ,  7  and  14 ) is driven into or pulled into opening  26 A within second slip  14 A, the hull  222  of the personal watercraft  220  slides on the weighted roller  30 A and serves to pull the arcuate side sections  18 A and  20 A toward the opposite sides of the hull  222  so that the hull  222  of the personal watercraft  220  fits snugly within the second slip  14 A as best illustrated in  FIG. 14 . As a result, due to this snug fit of each arcuate section  18 A and  20 A of sidewall  16 A being forced against the respective opposite sides of the hull  222 , the personal watercraft  220  is firmly retained within the second slip  14 A so it will not tip over and will not bump against a personal watercraft moored in an adjacent slip  14 . 
   The second key innovation of the present invention is the incorporation of a bow hook assembly which is used to retain a personal watercraft within a slip and also used to facilitate having the dock  10  moored offshore and retained by a stake or other anchoring means on the shore. Referring to  FIG. 13 , the bow hook assembly  40  comprises a bow hook  42  which is fastened on the nose  22  of first slip  14  and retained thereon by a first stopper member  44 . The bow hook  42  is fastened to a mating member  204  on the personal watercraft  200  to thereby retain the personal watercraft  200  within the slip  14 . The bow hook assembly  40  further comprises a strap member or cord  46  which extends within the dock  10  from the nose  26  to the front leading edge  32  of dock  10 . A second stopper member  48  within the dock  10  and a lock member  50  on the front leading edge  32  serve to retain cord  46  in a tight manner. A mooring cord  52  extends from the lock member. Similarly, a bow hook assembly  40  comprises a bow hook  42  which is fastened on the nose  22 A of second slip  14 A and retained thereon by a first stopper member  44 . The bow hook  42  is fastened to a mating member  224  on the personal watercraft  220  to thereby retain the personal watercraft within the slip  14 A. The bow hook assembly  40  further comprises a strap member or cord  46  which extends within the dock  10  from the nose  26 A to the front leading edge  32  of dock  10 . A second stopper member  48  within the dock  10  and a lock member  50  on the front leading edge  32  serve to retain cord  46  in a tight manner. A mooring cord  52  extends from the lock member. As illustrated in  FIG. 1 , the mooring cords  52  from each respective bow hook assembly are tied to a stake  8  which is implanted in the surface on the shoreline which surface can be sand, dirt, etc. As a result, the dock  10  can be moored offshore by any desired length such as 15 feet. As a result, the dock can be securely moored offshore by any desired distance so that the dock will not float away and the personal watercraft are securely retained in each slip so that the personal watercraft will not tip over or bump against an adjacent personal watercraft. 
   In addition, the first side  34  of the dock  10  can contain a multiplicity of D-rings  54  and the second side  36  can also contain a multiplicity of D-rings  56 . As a result, D-rings  54  can be interlocked with D-rings  56  of an adjacent dock so that two docks can be locked together. In this manner, any number of docks can be locked together to form a long island of slips. While D-rings have been illustrated, it will be appreciated any type of mating members including other types of hooks, mating hook and loop fasteners, etc, can be used in place of items  54  and  56  to fasten two adjacent docks together at their respective side edges  34  and  36 . Leading edge  32  also supports a multiplicity of D-rings  58 . A strap or rope  4  to which an anchor  6  is fastened to more securely retain the dock to assure that it will not float away can be attached at one or more D-ring locations. In the illustration the strap or rope  4  an anchor  6  are shown attached to D-rings  58  on the leading edge. However, the rope  4  and anchor  6  can be attached to each other on both side D-rings  54  and  56 . 
   The two slip dock  10  is made of inflatable synthetic material which is made of PVC plastic or rubber that can be inflated with gas such as air or helium to a pressure of 10 psi or less. By way of example, in one preferred embodiment, the overall width of the two slip dock  10  is 118 inches, the length of the two slip dock  10  is 84 inches, the height of the two slip dock  10  is 6 inches and the docking capacity is 2 personal watercraft. 
   Referring to  FIGS. 2 ,  4 ,  16  and  17  there is illustrated the second variation of the first alternative embodiment of the present invention which is a three slip docking system for personal watercraft. Referring specifically to  FIGS. 4 and 17 , there is illustrated at  110  the three slip docking system. The three slip docking system  110  is an inflatable raft having an inflation/deflation valve  112  by which a gas such as air is forced into the interior of the raft so that it expands into a raft as best illustrated in  FIG. 17 . The dock  110  has three slips for receiving a personal watercraft, a first slip  114 , and second slip  114 A and a third slip  114 B. Each slip is identical and aligned side by side and parallel to each other. First slip  114  which is at one outside area has a circumferential sidewall  116  having an arcuate side section  118  and a mirror image second arcuate side section  120  which converge in a nose section  122 . First slip  114  has an opening  124  which leads to an open space  126  between the arcuate side sections  118  and  120  into which a personal watercraft is received. Second slip  114 A which is on the opposite outside area has a circumferential sidewall  116 A having an arcuate side section  118 A and a mirror image second arcuate side section  120 A which converge in a nose section  122 A. Second slip  114 A has an opening  124 A which leads to an open space  126 A between the arcuate side sections  118 A and  120 A into which a personal watercraft is received. Third slip  114 B which is in the middle area has a circumferential sidewall  118 B having an arcuate side section  118 B and a mirror image second arcuate side section  120 B which converge in a nose section  122 B. Second slip  114 B has an opening  124 B which leads to an open space  126 B between the arcuate side sections  118 B and  120 B into which a personal watercraft is received. 
   One key innovation of the present invention is the incorporation of a rope  128  supported on each arcuate side section  118  and  120  of first slip  114  at a location adjacent opening  124  so that the rope extends between the arcuate side sections. A weighted roller  130  is supported on the rope  128  so that the rope  128  is submerged in the water on which the dock  110  floats. When a personal watercraft  300  (see  FIGS. 2 and 16 ) is driven into or pulled into opening  124  within first slip  114 , the hull  302  of the personal watercraft  300  slides on the weighted roller  130  and serves to pull the arcuate side sections  118  and  120  toward the opposite sides of the hull  302  so that the hull  302  of the personal watercraft  300  fits snugly within the first slip  114  as best illustrated in  FIG. 16 . As a result, due to this snug fit of each arcuate section  118  and  120  of sidewall  116  being forced against the respective opposite sides of the hull  302 , the personal watercraft  300  is firmly retained within the first slip  114  so it will not tip over and will not bump against a personal watercraft moored in an adjacent slip  114 B. Similarly, a rope  128 A is supported on each arcuate side section  118 A and  120 A of second slip  114 A at a location adjacent opening  124 A so that the rope extends between the arcuate side sections. A weighted roller  130 A is supported on the rope  128 A so that the rope  128 A is submerged in the water on which the dock  10  floats. When a personal watercraft  320  (see  FIGS. 2 and 16 ) is driven into or pulled into opening  126 A within second slip  114 A, the hull  322  of the personal watercraft  320  slides on the weighted roller  130 A and serves to pull the arcuate side sections  118 A and  120 A toward the opposite sides of the hull  322  so that the hull  322  of the personal watercraft  320  fits snugly within the second slip  114 A as best illustrated in  FIG. 16 . As a result, due to this snug fit of each arcuate section  118 A and  120 A of sidewall  116 A being forced against the respective opposite sides of the hull  322 , the personal watercraft  320  is firmly retained within the second slip  114 A so it will not tip over and will not bump against a personal watercraft moored in an adjacent slip  114 B. Similarly, a rope  128 B is supported on each arcuate side section  118 B and  120 B of third or middle slip  114 B at a location adjacent opening  124 B so that the rope extends between the arcuate side sections. A weighted roller  130 B is supported on the rope  128 B so that the rope  128 B is submerged in the water on which the dock  10  floats. When a personal watercraft  330  (see  FIGS. 2 and 16 ) is driven into or pulled into opening  126 B within second slip  114 B, the hull  332  of the personal watercraft  330  slides on the weighted roller  130 B and serves to pull the arcuate side sections  118 B and  120 B toward the opposite sides of the hull  332  so that the hull  332  of the personal watercraft  330  fits snugly within the second slip  114 B as best illustrated in  FIG. 16 . As a result, due to this snug fit of each arcuate section  118 B and  120 B of sidewall  116 B being forced against the respective opposite sides of the hull  332 , the personal watercraft  330  is firmly retained within the second slip  114 B so it will not tip over and will not bump against a personal watercraft moored in an adjacent slips  114  and  114 A. 
   The second key innovation of the present invention is the incorporation of a bow hook assembly which is used to retain a personal watercraft with a slip and also used to facilitate having the dock  10  moored offshore and retained by a stake or other anchoring means on the shore. Referring to  FIG. 13 , the bow hook assembly  40  comprises a bow hook  42  which is fastened on the nose  122  of first slip  114  and retained thereon by stopper member  44 . The bow hook  42  is fastened to a mating member  304  on the personal watercraft  300  to thereby retain the personal watercraft  300  within the slip  114 . The bow hook assembly  40  further comprises a strap member or cord  46  which extends within the dock  110  from the nose  122  to the front leading edge  132  of dock  10 . A second stopper member  48  within the dock  110  and a lock member  50  on the front leading edge  132  serve to retain cord  46  in a tight manner. A mooring cord  152  extends from the dock member. Similarly, a bow hook assembly  40  comprises a bow hook  42  which is fastened on the nose  122 A of second slip  114 A and retained thereon by stopper member  44 . The bow hook  42  is fastened to a mating member  324  on the personal watercraft  320  to thereby retain the personal watercraft  320  within the slip  114 A. The bow hook assembly  40  further comprises a strap member or cord  46  which extends within the dock  110  from the nose  126 A to the front leading edge  132  of dock  110 . A second stopper member  48  within the dock  110  and a lock member  50  on the front leading edge  132  serve to retain cord  46  in a tight manner. A mooring cord  152  extends from the lock member. Similarly, a bow hook assembly  40  comprises a bow hook  42  which is fastened on the nose  122 B of third or middle slip  114 B and retained thereon by stopper member  44 . The bow hook  42  is fastened to a mating member  334  on the personal watercraft  330  to thereby retain the personal watercraft  330  within the slip  114 B. The bow hook assembly  40  further comprises a strap member or cord  46  which extends within the dock  110  from the nose  126 B to the front leading edge  132  of dock  110 . A second stopper member  48  within the dock  110  and a lock member  50  on the front leading edge  132  serve to retain cord  46  in a tight manner. A mooring cord  52  extends from the lock member. As illustrated in  FIG. 2 , the mooring cords  152  from each respective bow hook assembly are tied to a stake  108  which is implanted in the surface on the shoreline which surface can be sand, dirt, etc. As a result, the dock  110  can be moored offshore by any desired length such as 15 feet. As a result, the dock can be securely moored offshore by any desired distance so that the dock will not float away and the personal watercraft are securely retained in each slip so that the personal watercraft will not tip over or bump against an adjacent personal watercraft. 
   In addition, the first side  134  of the dock  110  can contain a multiplicity of D-rings  154  and the second side  136  can also contain a multiplicity of D-rings  156 . As a result, D-rings  154  and be interlocked with D-rings  156  of an adjacent dock so that two docks can be locked together. In this manner, any number of docks can be locked together to form a long island of slips. While D-rings have been illustrated, it will be appreciated any type of mating members including other types of hooks, mating hook and loop fasteners, etc, can be used in place of items  154  and  156  to fasten two adjacent docks together at their respective side edges  134  and  136 . Leading edge  132  also supports a multiplicity of D-rings  158 . A strap or rope  104  to which an anchor  6  is fastened to more securely retain the dock to assure that it will not float away can be attached at one or more D-ring locations. In the illustration the strap or rope  4  an anchor  106  are shown attached to D-rings  158  on the leading edge. However, the rope  104  and anchor  106  can be attached to each other on both side D-rings  154  and  156 . 
   The three slip dock  110  is made of inflatable synthetic material which is made of PVC plastic or rubber that can be inflated with gas such as air to a pressure of 10 psi or less. By way of example, in one preferred embodiment, the overall width of the three slip dock is 166 inches, the length of the three slip dock  110  is 84 inches, the height of the three slip dock  110  is 6 inches and the docking capacity is 3 personal watercraft. 
   Referring to  FIGS. 18 through 24 , there is illustrated a second alternative embodiment of the present invention which is a dock island  60  which floats in the middle of a body of water such as a lake. Referring to  FIG. 22 , the dock island  60  has four spaced apart arcuate radial wings  62 ,  64 ,  66  and  68  which extend from a central body portion  70 . A first slip member  72  lies between wings  62  and  68  and has a circumferential sidewall  74  having an arcuate side section  76  on wing  62 , a partial mirror image side section  78  on wing  68 , and a nose section  80 . In addition to extending for the length of arcuate section  76 , the opposite arcuate section  78  extends for an additional length  79  which forms an extended sidewall portion of an adjacent wing  68 . A second slip member  72 A lies between wings  62  and  64  and has a circumferential sidewall  74 A having an arcuate side section  76 A on wing  64 , a partial mirror image side section  78 A on wing  62 , and a nose section  80 A. In addition to extending for the length of arcuate section  76 A, the opposite arcuate section  78 A extends for an additional length  79 A which forms an extended sidewall portion of an adjacent wing  62 . A third slip member  72 B lies between wings  64  and  66  and has a circumferential sidewall  74 B having an arcuate side section  76 B on wing  66 , a partial mirror image side section  78 B on wing  64 , and a nose section  80 B. In addition to extending for the length of arcuate section  76 B, the opposite arcuate section  78 B extends for an additional length  79 B which forms an extended sidewall portion of an adjacent wing  64 . A fourth slip member  72 C lies between wings  66  and  68  and has a circumferential sidewall  74 C having an arcuate side section  76 C on wing  68 , a partial mirror image side section  78 C on wing  66 , and a nose section  80 C. In addition to extending for the length of arcuate section  76 CB, the opposite arcuate section  78 C extends for an additional length  79 C which forms an extended sidewall portion of an adjacent wing  66   
   One key innovation of the dock island  60  is that the four slips  62 ,  64 ,  66  and  68  are positioned at 90 degrees to each other. Therefore, as illustrated in  FIGS. 23 and 24 , when the respective personal watercraft  400 ,  410 ,  420  and  430  are respectively moored in a respective slip  62 ,  64 ,  66  and  68 , each personal watercraft is at 90 degrees to the adjacent personal watercraft on either side of it. Therefore, each watercraft will not bump into either personal watercraft positioned on either side of it. 
   A second key innovation of the dock island  60  is the incorporation of a cental body portion  70  which is sufficiently large so that at least one person can lie on the body portion and sunbathe. In addition, as illustrated in  FIGS. 18 ,  19  and  23 , a canopy  82  can be affixed to the dock island by having a multiplicity of joining members such as cords  83 .  84 .  85  and  86  respectively connecting the canopy to an exterior location on each respective wing  62 ,  64 ,  66  and  68 . Therefore, a person can lie on the body  70  without a canopy as illustrated in  FIG. 24  to get more sun or can lie on the body  70  with the canopy  82  as illustrated in  FIG. 23  to get more shade. 
   The dock island is  60  is an inflatable raft having an inflation/deflation valve  88  (see  FIG. 22 ) by which a gas such as air is forced into the interior of the raft so that it expands into a raft as best illustrated in  FIGS. 23 and 24 . 
   The dock island  60  has at least one D-ring on at least one wing for the purpose of providing a means to support an anchor or means to connect one dock island to another. As best illustrated in  FIG. 22 , each wing has a respective D-ring. Wing  62  has D-ring or connecting means  90 , wing  64  has D-ring or connecting means  91 , wing  66  has D-ring or connecting means  92 , and wing  68  has D-ring or connecting mean  93 . An anchor  61  can be connected to a rope or strap  63  which in turn is connected to a D-ring to anchor the dock island  60  so it won&#39;t float away. For maximum anchoring, an anchor can be attached in this manner each of the four D-rings. At least one anchor connected to at least one D-ring is necessary to assure that the dock island will not float away. 
   One dock island  60  can be connected to another dock island  60  by attachment of one D-ring from one dock island to a ring of another dock island. Also, a long rope can be attached to at least one D-ring to anchor the dock island  60  off a shoreline, in a manner comparable to the anchoring illustrated off a shoreline in  FIGS. 1 and 2  where the other end of the rope is affixed to a stake  8  embedded into the ground in dirt or sand. 
   Each slip has a bow hook affixed to a nose portion. As best illustrated in  FIG. 22 , As best illustrated in  FIG. 22 , slip  72  has bow hook  94  attached to a flexible cord  71  in the nose section  80 ; slip  72 A has bow hook  95  attached to a flexible cord  73  in the nose section  80 A; slip  72 B has bow hook  96  attached to a flexible cord  75  in the nose section  80 B; and slip  72 C has bow hook  97  attached to a flexible cord  77  in the nose section  80 C. Each bow hook is fastened to a mating member on a personal watercraft to thereby retain the personal watercraft within a respective slip, as illustrated in  FIGS. 23 and 24 . 
   Through the present invention dock island  60 , the dock island  60  can be anchored in the middle of a body of water so that it is not necessary to return to shore to moor a personal watercraft and the personal watercraft can be moored in the middle of the body of water while the person relaxes and sunbathes on the body  70  of the dock island  60 . Four personal watercrafts can be moored on one dock island and positioned at 90 degrees to each other so that they will not bump into an adjacent personal watercraft. Any type of personal watercraft can be used with the present invention dock island. 
   The dock island  60  is made of inflatable synthetic material which is made of PVC plastic or rubber that can be inflated with gas such as air or helium to a pressure of 10 psi or less. By way of example, in one preferred embodiment, the overall diameter of the dock island is 180 inches, the height with the canopy attached is 180 inches, the overall diameter of the canopy of 129 inches, the height of the canopy is 72 inches, the docking capacity is 4 personal watercraft and the maximum occupancy is 6 adults.
