## Abstract

Structural arrangement for a water ski or underwater ski comprising essential mechanisms for significantly improving the user experience in underwater wake bodyboarding. The ski is characterized by the addition of novel and different attachable items that enable the ski to be used without a powered vehicle. The ski is also characterized in that it has various different items that can be attached to the cowling to improve the performance and comfort of the equipment, combined with a personalized steering system and an essential safety system, providing a model that is unique on the underwater ski/water ski market.

## Claims

### Claim 1

A water ski, useful for wake bodyboarding, comprising:
a base support,
a towing shaft is attached to the support, said towing shaft has holes at each end to which cables which may be connected for use by a vessel to tow the water ski,
a set of handlebars connected to a central shaft, the shaft passes through a hole in said base support and is connected to a steering system underneath the base support and configured such that the water ski trajectory can be controlled by use of the handlebars,
a safety device comprising a rope in which one end is attached to the athlete's wrist and the other end is attached to the ski by way of a safety system,
the safety system will automatically detach the rope from the ski when the athlete puts tension on the rope
a set of two keels are attached symmetrically to lateral underside of the base support.

### Claim 2 (depends on 1)

The water ski as defined in claim 1 further comprising a propeller.

### Claim 3 (depends on 1)

The water ski as defined in claim 1 further comprising double propellers located on the sides of the ski.
