A mat 10 preferably made of cell foam or foam rubber materials of rectangular shape is releasably affixed to sleeve 51 by pressure from fastener 20 to sleeve 51. In some embodiments multiple pieces of foam material may be used. Examples of materials include, but are not limited to, polyethylene and ethylene vinyl acetate. These materials are generally lightweight and permanently buoyant. Washer 21 is placed between fastener 20 and mat 10 to provide additional surface area to apply downward pressure from fastener 20. A plurality of fastener 20 and washer 21 structures may be placed along the contact surface of mat 10 where mat 10 attaches to sleeve 51. Sleeve 51 is shaped such that sleeve 51 fits around center tube 50 when center tube 50 is slid inside sleeve 51. Center tube 50 must be allowed to rotate within sleeve 51 in order to transfer the rotational force necessary to wind mat 10 around sleeve 51. Center tube 50 includes releasable protrusions 52 such that releasable protrusions 52 prevent center tube 50 from sliding out of sleeve 51. Releasable protrusions 52 may be attached to center tube 50 via screw threading and corresponding threaded hole in center tube 50 or any tackifier or other adhesive material. Handle 30 is releasably attached to sleeve 51 such that handle 30 may remain affixed relative to sleeve 51. Handle 30 may be able to rotate relative to center tube 50 if a user provides the force necessary to rotate sleeve 51 around center tube 50. Handle 30 includes an user interface such that a user may hold the user interface in position, and the user interface will rotate relative to handle 30 when used to provide a fixed location for a user's hand relative to the rotation of handle 30.

Apparatus 100 has a floatable water mat 110 of rectangular shape releasable affixed to watercraft 101 with straps 111 and 112. Straps 111 and 112 are secured to clips 113 and 114 located on the front side of mat 110 on opposite corners of the inner end of mat 110. Clips 116 and 117 are located on the back side of mat 110 opposite from clips 113 and 114 to facilitate assembly and allow the front and back sides of mat 110 to be interchangeable. Clips 113, 114, 116 and 117 are preferably D-ring clips having flush mount plates fastened to mat 110. Other types of clips or securing members attached to mat 110 can be used to accommodate straps 111 and 112.
(25) The outer ends of straps 111 and 112 are affixed to hook members 118 and 119. Hook members 118 and 119 are adapted to hook structure of watercraft 101 to releasably attach the inner end of mat 110 to watercraft 101. Hook members 118 and 119 are preferably S-hooks having an open end adapted to engage and hook onto watercraft structure and hardware. Other types of hook members, such as carabiner-style clips, can be used to attach straps 111 and 112 to watercraft structure and hardware. Alternatively, straps 111 and 112 may be tied directly to the watercraft.
(26) Slack adjusting members 121 and 122 mounted on straps 111 and 112 allow slack to be pulled out of straps 111 and 112 to tightly secure the inner end of mat 110 to watercraft 101.
(27) A pull up strap 123 attached to the outer end of mat 110 is used to pull the outer end of mat 110 toward watercraft 101 and fold the outer end of mat 110 toward the inner end of mat 110. Pull up strap 123 is secured to a clip 124 located on the back side of mat 110 adjacent the outer end of mat 110. A tie up strap 126 secured to clip 128 located on the back side of mat 110 is used to anchor mat 110 in a rolled position on watercraft 101. Tie up strap 126 is attachable to watercraft structure 127 to hold mat 110 in the rolled position, as seen in FIG. 11. Clips 129 and 131 are located on mat 110 opposite from clips 124 and 128 to facilitate assembly and allow the front and back sides of mat 110 to be interchangeable. Clips 124, 128, 129 and 131 are preferably D-ring clips having flush mount plates fastened to mat 110. Other types of clips and securing members attached to mat 110 can be used to accommodate straps 123 and 126.
