Multi-purpose, plastic molded, sit-on-top kayak

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.
