Spark Plug Retro – Modern Twin Fin Meets Classic Volume

The Spark Plug Retro builds on the modern performance twin fin foundation of the original Spark Plug, blending contemporary design with the fuller foam and feel of classic boards. It features a balanced, fuller thickness foil through the nose and tail, paired with a flatter deck profile and dropped angular rails that add subtle lift and stability while maintaining responsiveness.

The nose outline is slightly fuller, complementing the thicker volume distribution to provide easier paddling and smooth wave flow. The board retains moderate nose lift and a low tail rocker with vee off the tail for controlled release and maneuverability. Bottom contours include a slight single concave through the center, evolving into a double concave in the fin area for optimized lift and drive.

Fins are set further back to increase speed, hold, and control, and the tapered rails through the fin zone allow the board to knife sharply into the wave face. The outline balances a fuller nose for paddling with a straightened curve between the feet, enhancing speed and rail hold.

Pros:

  • Fuller foil and volume provide effortless paddling and stability

  • Flatter deck with dropped rails offers a blend of lift and control

  • Double concave contours increase lift and smooth rail transitions

  • Set-back fins improve speed and responsiveness

  • Balanced outline for versatile performance in various conditions

Cons:

  • Fuller volume may feel less agile for surfers used to more minimal shapes

  • Retro volume might not suit very steep or hollow waves

Summary:
The Spark Plug Retro is a successful fusion of modern twin fin performance and classic volume, delivering easy paddling, smooth flow, and sharp control. It’s an excellent choice for surfers who want a responsive board with a bit more foam and stability, perfect for a wide range of waves and skill levels.
