A plastic molded, sit-on-top kayak of unique size and shape is disclosed with various components which provide multi-purpose usage. The kayak is especially useful for multi-purposes such as sailing kayak surfing, scuba diving, paddling, touring and electric motorized usage. The kayak has attachment points integrally molded that provide for these multi-purposes. An important component of the invention includes a removable backrest that additionally provides secure waterproof storage of the operator's personal items. The backrest can be easily removed and reattached securely in place when desired. The ability to easily remove a backrest or backpack option also enables a desirable compact capability for transportation and storage by a user. Additional benefits of this feature provide for a smaller profile for packaging and commercial transportation. The kayak as disclosed may be formed for the most part, typically by blow molding, rotational molding, injection molding, rim molding, fiberglass and thermoforming, and by using a wide variety of polymer materials that may be suitable.

The invention claimed is: 1. A plastic formed, sit-on-top kayak defining a flat, continuous bottom surface, a downwardly sloping front end which together with two outer grooves and a centrally V-shaped reinforcing groove for directing water flow along the bottom surface, thereby improve directional stability and control, and a raised, reinforcing ridge disposed centrally along the kayak and extending forwardly from a rear support seat and extending near the front end of the kayak, the reinforcing ridge together with the V-shaped reinforcing groove thereby improving structural integrity, the sit-on-top kayak defining a double-wall storage space positioned rearward of the kayak, and a partially squared-off tail end behind the storage space forming a mounting platform for attachment thereto of items including a propulsion unit and a rudder and surfing fin, the storage space and squared-off tail providing a stable base having sufficient tensile strength to impart structural integrity to the kayak during use of these items, the reinforcing ridge defining at least one bore hole for securing items, including one or more of a sail, flag indicator, a water bottle holder, recessed trays and a fishing pole. 2. The sit-on-top kayak of claim 1, which provides a removable back rest and removable storage space to enable a user to carry a portion of a kayak load, thereby enabling separate transportation of the kayak. 3. The sit-on-top kayak of claim 1, providing a removable, integrally molded back pack and back pack with attachment straps for carrying purposes. 4. The sit-on-top kayak of claim 3, including an integrally molded, removable back rest and storage unit for carrying purposes. 5. The sit-on-top kayak of claim 1, defining U-shaped outer grooves and a V-shaped reinforcing central groove. 6. The sit-on-top kayak of claim 1, including a partially squared-off tail end of the kayak, that increases flotation for a given length, and provides a stable base for standing the kayak up against a flat vertical surface enabling efficient storage and transportation. 7. The sit-on-top kayak of claim 1, in which the back rest is hand removable. 8. The sit-on-top kayak of claim 1, defining two outer grooves and a central, continuous reinforcing groove along the bottom surface. 9. The sit-on-top kayak of claim 1, in which reinforcing foot rests are defined on both sides of the reinforcing ridge. 10. The sit-on-top kayak of claim 1, providing a sail structure including control ropes slidably connected to an upper mast portion of the sail, at their lower end, the control ropes being connected to the kayak adjacent the operator, whereby slidable retraction or loosening of the control ropes will reduce or increase wind exposure of the sail, thereby effecting speed control and tracking direction by the operator.
