Surf Futures F4 Blackstix 3.0 Small Thruster Set Fins

Instant Acceleration and Reactive Turns for Lightweight Surfers with the F4 Template in Blackstix 3.0 Construction

Completely transform your board's performance in small to medium waves with the Futures F4 Blackstix 3.0 Small fin set. Specifically designed for lightweight surfers or young talents (size S: 45 to 60 kg), this set is the absolute market benchmark for actively generating speed in soft sections of the wave.

The Blackstix 3.0 construction stands out for combining an ultra-rigid asymmetrical carbon fiber base with a flexible core that smooths the flex at the fin tip. Thanks to its innovative V2 Foil (a three-dimensional concave profile on the inner face of the side fins), these fins act like an aerodynamic wing, sucking in water to generate lift and instant acceleration with each pump. With a Speed Generating Ride Number category, the F4 Blackstix set allows you to maintain glide in the deadest sections of the wave, ensuring a fluid, fast, and very fun surf.

Technical Specifications and Dimensions (Size S | 45 - 60 kg):

• Side Fins: 4.22" base, 4.37" height, and 14.22" area with a concave V2 Foil profile for maximum hydraulic thrust and effortless rail-to-rail transitions.

• Center Fin: 4.22" base, 4.37" height, and 14.22" area with a symmetrical profile (Symmetrical Foil) for impeccable trajectory control in the tail.

• Blackstix Carbon Technology: Unidirectional carbon in the base for greater structural rigidity, combined with an elastic core that stores energy and returns it explosively when exiting each turn.

• All-Around F4 Template: A balanced and versatile design that facilitates both vertical surfing and wide turns on the wave face.

• Ride Number Speed Generating: Reactive flexibility specifically designed to actively generate speed in everyday, powerless wave conditions.

Compatibility: This set includes 3 fins (Thruster / tri-fin system) exclusively compatible with single tab (Single Tab / Futures) fin boxes.
