 Project Description  Current State  Desired State  Stakeholders  Customer Requirements  Engineering Requirements  Project Schedule

Two previous revision of the Skipper’s Chair have been designed for disabled individuals to maneuver the Sonar Sailboat under recreational and competitive use. This design easily allows one person to perform the necessary tasks typically allocated for multiple people.

 Seat is adjustable for 90% of populace  Fits in a regulation sonar boat  Has quick release tiller  Ready for competition and daily use  Requires minimal effort from the user

 System weight is too heavy  Installation time is long  Too many custom machined parts  Did not meet boom height requirement  Complicated installation ◦ Needed own tool box

 Minimal customized parts  Minimal assembly, installment, and adjustment time  Must have simplified instructions for volunteers

 Minimal weight without reducing comfort/safety  Materials must be impervious to environmental effects/wear  Maximize Factor of Safety

 Minimize cost of system  Reduce assembly time ◦  Build time = 30 minutes  Assembly time = 15 minutes  Adjustment time = 30 minutes  Maintain safety and personal adjustment capabilities
