## Abstract

The present invention provides the maximum convenient portability with a 3 foldable method of the water ski hull, one half dividable shaft method of ski pole and a separable propulsion plate method from the ski pole, a push-pull method of rudder, and a separable method of the lateral balancing board from the hull, and also provides the maximum lateral balance effect of a skier by means of the lateral balancing board at the mid section, two side wings at the stern section, and a foot skid pad on each side of the mid section and a Velcro belt on each side holding each side instep of a skier over each side foot skid pad of the mid section of the ski hull.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

In the claim 1, the man-powered water ski with the feature increasing the lateral balance of the ski hull by the lateral balancing board.

### Claim 3 (depends on 1)

In the claim 1, the man-powered water ski with the feature increasing more the lateral balance of the ski hull by the extended auxiliary lateral balancing wings.

### Claim 4 (depends on 1)

In the claim 1, the man-powered water ski with the feature increasing most the lateral balance of the ski hull by the foot skid pads and the instep Velcro belts.

### Claim 5 (depends on 1)

In the claim 1, the man-powered water ski with the feature increasing the speed of the ski by reducing water friction of the lateral balancing board due to inclining backward of the said board as a skier thrusts the ski forward.
