Man-powered water ski with the maximum portability and the maximum lateral balance

A ski hull dividable into 3 sections and 3 layer foldable, a ski pole dividable into 2 parts at the mid spot of the shaft, a propulsion medium like a plate separable from the shaft at its end part, two auxiliary lateral balancing wings adjustable and attachable at each side recess of the stern section of the ski hull, a rudder at the bottom of the stern section push-able into its housing, a lateral balancing board separable from the mid section, and a portable ski case packed with all the said elements of the ski embodiment provides the feature of the maximum convenient portability effect. The lateral balancing board fixed vertically at the bottom of the mid section of the ski hull increases the lateral balance of the ski hull, the auxiliary lateral balancing wings extended outwardly each side of the stern section increases more the lateral balance of the ski hull, and both foot skid pads and both instep Velcro belts located each side of the mid section deck of the ski hull increases most the lateral balance of the ski hull. Those said 3 methods of the lateral balance provide the maximum lateral balance effect of a ski hull.
