BackgroundThe Skipper’s Chair is used to secure the user and allow access to the tiller, which is used for steering.
The tiller is attached to the submerged rudder, which directs the sailboat.
The 1st Senior Design iteration was developed for only one user, Richard Ramos.
The 2nd Senior Design iteration strived to develop an ergonomic, safe, and comfortable design for the majority of the population.

Successes:● Fits in a regulation Sonar Sailboat● Seat adjustable to 90% of
individuals● Contains quick release tillerFailures:● Fails to maneuver Sonar Sailboat● 117 lbs.● Long installation time:
- 30 min. assembly- 15 min. installation- 30 min. adjustment
● Many different custom parts - 400+ machining hrs.

Current Product - P13032
• The scope of the project is to design a device that allows a disabled individual to act as a skipper on a Sonar sailboat.
• The ideal goal of the device is to steer the boat as a lightweight, and cheap design that is an easily manufacturable assistive sailing device.

Problem Statement
Systemic:● Non-permanent attachment● Purely mechanical system● Conformance to racing standards
Independant:● Budget● Time
