Futures Thermotech Performance Longboard Single Fin

The Futures Thermotech Performance Longboard Single Fin is an all-around center fin built for performance longboards, mid-lengths, SUP surfboards, and 2+1 setups. Available in 6", 7", and 8" sizes, this fin gives surfers a simple way to tune their board for looser turning, balanced control, or added hold.

Made in Huntington Beach with Futures’ Thermotech construction, the Performance Longboard fin is designed to avoid the stiff plastic feel of basic composite fins. Instead, it offers consistent flex that helps create drive through turns and smooth release when redirecting the board.

Why It Works

• All-around performance longboard template works as a single center fin or in a 2+1 setup.
• Thermotech construction provides consistent flex for drive and release through turns.
• 6" size loosens up smaller boards and 2+1 setups.
• 7" size offers balanced control for everyday performance longboarding.
• 8" size adds more hold and stability for longer boards or stronger turns.
• Symmetrical foil gives the fin predictable center-fin performance.

Perfect For

The Futures Thermotech Performance Longboard Single Fin is ideal for longboards, mid-lengths, SUP surfboards, and boards set up as a 2+1. Choose the 6" for a looser feel, the 7" for balanced everyday performance, or the 8" for added hold, drive, and stability.

Size Selection Guide

Fit Tip: Size down for a looser, more maneuverable feel, or size up for more hold and stability. For 2+1 setups, many surfers choose a smaller center fin than they would use for a dedicated single-fin setup.

How It Compares

Compared to a larger traditional single fin, the 6" and 7" Thermotech Performance fins create a looser, more responsive feel, especially when paired with side bites. Compared to smaller center fins, the 8" version adds more drive and hold for longer boards, heavier surfers, or stronger turns.

Bottom Line: The Futures Thermotech Performance Longboard Single Fin is a versatile center fin available in 6", 7", and 8" sizes, built for surfers who want dependable Thermotech flex, all-around performance, and easy tuning for single-fin or 2+1 setups.
