5.7" Upright Twin Fins, black Pro Glass. Futures compatible set of two fins.

A classic upright, wide-base twin fin design.

1. Upright outline

• More vertical leading edge than a keel

• Less rake (sweep)

• Promotes quick pivot and tighter turning radius

2. Wide base

• Strong base area gives drive and hold, especially off the bottom

• Maintains speed through flat sections

• Prevents the “skatey” feeling some upright twins can have

3. Medium tip height

• Taller than many modern keel fins.

• Helps balance release vs control

4. Foil style

• Flat foil on the inside face

• Encourages speed and immediate response

• Clean water release down the line

  Overall feel in the water

  The Upright twin fin template is best described as:

  • Fast

  • Loose but not uncontrolled

  • More pivot than a keel

  • More drive than ultra-upright performance twins

  Best board pairings

  • Fish with moderate rocker

  • Modern retro twins

  • Shorter mid-length twins

  • Boards ridden with front-foot trim + back-foot pivot

  Surf conditions it suits

  • Small to medium surf

  • Clean beach breaks

  • Points where speed + direction change matter

  In short

  The Upright Twin Fin template is a balanced upright twin that delivers speed, drive, and controlled looseness—ideal for surfers who want twin-fin flow without giving up directional control.
