Fluid Dynamic Analysis and Comparison of
Windsurfing Fins

• MER 197 Union College Senior Design Project Fall
  2004
• John Gallagher
• Advisor Professor Anderson

Outline

• What I Have Done
• Research on fins
• Research on fin design and companies
• What I Plan on Doing
• Relation to timeline
• The rest of fall term
• Winter term

Fin Design

• Many Companies
• Mass production large companies
• Custom fin design small companies
• Modern Design Techniques
• Fluid dynamic design
• CAD, Wind tunnel
• Rapid prototyping
• Construction from mold

Fin Design Standard Fins

• (MFC VS Keith Teboul)
• Wave Fin
• Wide base
• - carving in waves
• Narrow tip
• - good control

• (MFC The Move)
• All Around Fin
• Good in high wind
• Good control

• (MFC Liquid)
• High Wind Race Fin
• Deep, wide
• Good upwind tracking
• Stable in high wind

5
Fin Design Alternate Fins

• (True Ames Fins Shallow Water)
• Shallow Water Fin
• Short, wide
• Avoid hitting ground
• in shallow water

• (Curtis Weed Deep Tuttle)
• Shallow Water Weed Fin
• Large rake angle
• Avoids getting hung up on
• weeds

Future Plans

• Kept Up-To Date with My Initial Timeline
• Problems that have arose
• Testing
• SolidWorks
• Wind tunnel
• Winter Term Plans
