2 Project Motivation: To provide an expanded and enhanced sailing experience for sailors with varying disabilities Project Goal: To design a mechanical solution to move a jib trimmer from side to side on a Sonar class sailboat, allowing them to function as a member of the crew.

3 Concept heavily influenced by space constraint required due to Captain s Chair 23 front to back available Cantilevered design fit best in space constraint Rotational and translational movement required for jib trimmer

4 Gary & Zak No leg mobility / core support Desires to be fully secured Cindy Partial leg & core strength Desires freedom to exit seat when necessary Limited footprint available due to P13032 s chair Cindy needs the option to sail with Gold Medal Chair or as a standalone device

5 Two systems were to be built, requiring a comprehensive design to fit varying needs Cantilevered seat most viable option to fulfill needs at expense of weight, time and money

6 Main components: Baseplate platform Side seat platforms Bench Lazy susan Seat Purchase system Handholds Points of contact with the boat are: Baseplate, side seat platforms, handholds, purchase system

7 Modeled on previous baseplate Legs are bolted through metal plate underneath Base clamps to bilge cover Allows adjustability forward and backward

8 Protects boat from interference with jib transfer bench Provides surface to distribute any forces from system Parts of purchase system mounted to these platforms

9 Pillow block and carriage provide linear motion on bar and track Most expensive component in system Heaviest component Most complex to install

10 Durable lazy susan Greased bearings Rigid against torque Provides enough friction for braking, but allows easy rotation too

perfect angle Slots in plates allow for extension into

11 Provide adjustability to any Sonar handhold Slides along 80/20 in X- Direction 80/20 design allows for rotation to perfect angle Slots in plates allow for extension into handhold cups Turnbuckle gives max adjustability and security

12 Mounted behind occupant. Travels the width of device Designed to give a 3-1 advantage

14 Top of swivel stool used Lap belt for support

15 System moved forward on baseplate with front handhold used Limits space for Cindy to move

16 Bucket seat and 5- point harness provide support Leg supports

20 System is overweight Had to be robust due to space limitation System is expensive System is unable to be manufactured on a large scale in its current design Some specifications are not feasible Adjusting for multiple configurations is time consuming

21 Zeb worked on the PRP to iterate this project again in the 2014 school year Eliminate space constraint due to Captain s Chair Reduce weight Reduce cost More off-the-shelf parts Less machining Better corrosion resistance Re-evaluate specs Evaluate feedback on rotation if it needs a brake mechanism
