Abstract

Drag Comparison

  • The drag due to the two surfing setups is very similar
  • Thruster - 3 fins
  • Twin - 2 fins

Drag Per Surface

  • Though both setups have similar drag, a twin fin setup has a more efficient use of surface area.
  • Using fewer, larger fins can be more efficient than using more, small fins.
