Team Upperclass

• Follow Up Presentation
• Solar Boat Project

Design Modifications

• Hull Designed changed twice on the fly.
• Nose spine easier to construct with canoe like
  shape. (modification 1)
• Hull impossible to fit to said shape
  (modification 2)
• Structure of nose supports changed from parallel
  to bulkheads to perpendicular.

3
Construction

• Spine modified for easier hull assembly
• Perpendicular struts removed and replaced with
  2x6 custom cut curves.

4
Power

• Designs called for Maximum Power Point Tracker
  for Solar Cell Optimization.
• Resources dictated a simple battery charging
  system was sufficient.

5
Circuit

• Circuit designed to pull energy from batteries
  while the cell recharged them.
• Constant voltage monitoring necessary to prevent
  overheat.

6
Propulsion

• Motor was internal to the boat, drive shaft
  through hull at 20 with horizontal.
• Original motor was 24V _at_ 6A, which required the
  batteries to be in series for sufficient voltage.
• After total system failure, a new motor was
  acquired, and install. Rated at 12V.

7
Steering

• Steering was a cable and pulley system.
• Dual rudders controlled by two linked control
  sticks via switchboard cable.
• A six point pulley system kept the cables in
  alignment during steering.
• Switchboard cable not as strong as anticipated.

Budget

Conclusion

• Boat proved particularly stable (and heavy)
• Propulsion/Power system, while lacking speed,
  could be used continuously as long as there was
  sun to charge the battery bank.
• Look for a website on the department site
  outlining the entire project.
