Typically, the adapter is detachable from the support leg and includes a ridge to mate with a corresponding channel and recessed cavity in the receiver. The result is a wheel assembly to repositionably secure the support leg between a first position and at least a second position that is generally angular offset from the first position, thereby securing the leg and preventing rotation about the watercraft. ## Claims ### Claim 1 A retractable wheel assembly adapted to support and transport a watercraft, said assembly comprising: a. a receiver secured to an upper surface of said watercraft, said receiver comprising a plurality of extensions; b. an adapter repositionable within said receiver between a first position and at least a second position angular offset from said first position; and c. an elongated leg having a proximate portion secured to said adapter and having a distal wheel, and wherein said adapter having a first body with an inner cavity and a second body with an inner cavity, whereby said first body and said second body adapted to receive said proximate portion. ### Claim 2 (depends on 1) The assembly of claim 1, wherein said adapter being repositionable within said receiver's inner mating face. ### Claim 3 (depends on 1) The assembly of claim 1, wherein said first body having at least one ridge. ### Claim 4 (depends on 3) The assembly of claim 3, wherein said adapter includes a pair of substantially perpendicular walls and a substantially planar top surface. ### Claim 5 (depends on 1) The assembly of claim 1, wherein said elongated leg includes a proximate rail and an elbow adjacent a vertical portion. ### Claim 6 (depends on 1) The assembly of claim 1, wherein said elongated leg includes an axle. ### Claim 7 (depends on 1) The assembly of claim 1, wherein said elongated leg adapted to extend downward below a waterline of said watercraft. ### Claim 8 (depends on 1) The assembly of claim 1, wherein said elongated leg adapted to align substantially parallel to a waterline of said watercraft. ### Claim 9 (depends on 1) The assembly of claim 1, wherein said receiver's inner mating face includes a channel and a plurality of recessed cavities extending along at least a portion of a length of said receiver. ### Claim 10 (depends on 1) The assembly of claim 1, including a mounting bracket adapted to mechanically attach said receiver to an upper surface of said watercraft. ### Claim 11 (depends on 1) The assembly of claim 1, wherein said adapter being connectable to and disconnectable from said receiver, and whereby said adapter positioned in said receiver prevents rotation of said elongated leg. ### Claim 12 A universal wheel assembly for transporting a watercraft, said assembly comprising: a. a first knuckle receiver and a second knuckle receiver spaced horizontally adjacent one another and adapted to be attachable to said watercraft; b. an adapter repositionable within each one of said knuckle receivers between a first position and at least a second position angular offset from said first position; and c. a pair of wheeled support legs having a proximate portion affixed to a respective one of said adapters and a distal portion supporting a wheel, and wherein said adapter having a first body with an inner cavity and a second body with an inner cavity, whereby said first body and said second body adapted to receive said proximate portion. ### Claim 13 (depends on 12) The assembly of claim 12, wherein said adapter being separable from said wheeled support leg. ### Claim 14 (depends on 12) The assembly of claim 12, wherein said adapter includes a plurality of ridges spatially offset from one another along a perimeter of said adapter. ### Claim 15 (depends on 12) The assembly of claim 12, wherein said support leg includes an elbow adjacent said proximate portion and a vertical portion. ### Claim 16 (depends on 15) The assembly of claim 15, wherein said proximate portion being substantially perpendicular to said vertical portion. ### Claim 17 (depends on 12) The assembly of claim 12, wherein said support leg includes an elbow adjacent said distal portion and a vertical portion. ### Claim 18 (depends on 12) The assembly of claim 12, including a central arm extending between said first knuckle receiver and said second knuckle receiver. ### Claim 19 A retractable wheel assembly to support and detach from a watercraft, said assembly comprising: a. a knuckle receiver secured to said watercraft and comprising i. an inner mating face, ii. an exterior surface having a first, second, third, and fourth extensions, said first and second extensions opposing one another and said third and fourth extensions opposing one another and said first and second extensions being substantially perpendicular to said third and fourth extensions, and iii. a recessed slot spaced between adjacent extensions; b. an adapter comprising i. a first body having an inner cavity and at least one ridge, ii. a second body having an inner cavity and at least one ridge, and iii. a fastener releasably securing said first body about said second body; and c. an elongated leg comprising i. a proximate rail secured between said first body and said second body, ii. a distal rail adapted to secure a wheel.
