The Futures Fins JC1 Blackstix 3.0 in size Medium is a high-performance thruster setup designed by shaper John Carper of JC Surfboards. It is engineered specifically as a "speed-generating" fin built to excel in smaller, softer, or low-power wave conditions. • Template (Drive & Hold): The JC1 features a traditional template layout paired with a refined base that carries into a full, wide tip. This design maximizes drive and provides plenty of area to hold onto powerful turns on the rail, even when the wave lacks punch. • V2 Foil Technology: It utilizes Futures' proprietary V2 inside foil, which features a concave design at the base that transitions to a flat foil at the tip. This creates lift, helps generate effortless speed, and guarantees fluid, buttery transitions from rail to rail. • Blackstix Construction: As part of the Blackstix series, these are among the lightest fins Futures makes. They incorporate a precise carbon fiber and fiberglass matrix embedded with a lightweight core. This gives the fin tip a soft, springy flex pattern with high resonance, meaning it snaps back quickly when you pump the board, projecting you forward down the line
