Design Problem Flaws in the Current Design Safety Issues Back Injuries Ankle/Leg Injuries Hardware Issues Poor Interface Foot Restraints Comfort Issues No Adjustability High Impact Chafing Nick 2/18/2019
Design Goals To redesign the current FitSki incorporating four major components: Enhanced safety for the skier Reduction of the shock loading on the skier Improvement of the interfacing of the FitSki with the board surface Increased seating comfort Cory 2/18/2019
First Prototype Meeting the Design Goals New foothold design Shock absorber placed beneath the seat Wakeboard-like pads for the interface New strap-in design, padded seat, and shock absorber 2/18/2019
First Iteration Seat Design Stiff design Not able to fit all sizes Uncomfortable Expensive Lorielle 2/18/2019
Revised Seat Design Adjust to various sizes Increased padding Prevents back injuries Compatible with our design Affordable Lorielle 2/18/2019

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.
