The Twin is best for smaller, weaker waves, letting intermediate surfers perform more radically with less technique.

It stays lively throughout the wave, generating easy speed and quick recoveries. Despite its small-wave focus, it can handle well overhead surf, pumping off the bottom and racing sections.

Compared to the Spice and Pro, the Twin is looser and unlocks speed faster. The Pro remains the high-performance choice in bigger, critical conditions, delivering top hold and control. The Spice offers versatility with quad or thruster setups, plus bevel rails for smooth rail-to-rail transitions and added hold.

The Twin complements but doesn’t replace either, appealing to those seeking relaxed lines, high-speed arcs, and tail slide turns.

Features of the Starboard Twin Fin:

  • ULTIMATE SPEED & FLOW: Enjoy fast down-the-line speed with reduced drag and a refined channel. The Twin Fin keeps you flowing even through weaker sections, linking maneuvers with ease and maintaining momentum.
  • EFFORTLESS TURNS & LOOSER FEEL: A looser, skatey ride makes sharp pivots and tail slides second nature. The hip and moon tail create a natural pivot point, ensuring quick direction changes and smooth transitions.
  • VERSATILITY ACROSS WAVE SIZES: Surprisingly adaptable in overhead waves, the Twin Fin provides enough hold to pump off the bottom and boost off the lip. Ideal for intermediate surfers seeking easy speed or pros craving stylish performance.
