Design Goals

• To redesign the current FitSki incorporating four major components:

1. Enhanced safety for the skier2. Reduction of the shock loading on the

skier3. Improvement of the interfacing of the

FitSki with the board surface4. Increased seating comfort

First Prototype Meeting the Design Goals

1. New foothold design2. Shock absorber placed beneath the

seat3. Wakeboard-like pads for the

interface 4. New strap-in design, padded seat,

and shock absorber

Background

• Adaptive water skiing has grown into a popular recreational activity for people with disabilities who experience an increased quality of life when they can be involved in physically active recreational activities. In the Healthy People 2010 report there is a strong emphasis on the need for physical activity for all people because of its close relationship to health and well being. Enhancing the accessibility and safety of outdoor recreation activities, such as water skiing, for people with disabilities will ensure that they have access to all of the health benefits that a physically active lifestyle provides.
