10. 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.

13. Safety and Performance
Foot Restraint
Velcro
Molded flexible rubber
Shock Absorbers
Options:
Air, Coil Springs, Oil (dampening)
Concerns
Loading Capabilities
Tune-ability
Durability/Corrosion Resistance
Height Of User Above Board
higher position=increased performance + decreased stability
lower position=decreased performance + increased stability
Seat Options
Personalized molded seat

15. Future Work SolidWorks model completion
Research machine shops to have it made or begin construction ourselves for a first working prototype
Website updates
Future testing
Lauren
Later add physical construction beginning

16. Conclusions
Witnessed first-hand the poor interface, shock loading, and the sores from the current seat
A new design is needed
Focus on Wakeboard
