The SUP Thruster RTM – FCS fin set includes two side fins used to complement a center fin (sold separately) and create a thruster configuration. Common in surfboards and increasingly popular in wave-oriented SUP boards, this setup provides enhanced drive, grip, and turning performance.

Mounted on either side of the board’s central fin box, side fins improve rail-to-rail control and offer better hold in turns – particularly useful when riding waves or carving tight lines. Compared to a single-fin setup, a thruster configuration delivers a more dynamic, responsive feel underfoot. These fins are built using RTM (Resin Transfer Molding) technology, giving them a perfect balance of stiffness, low weight, and durability.

The fins are compatible with all SUP boards featuring FCS (Fin Control System) side slots. Tool-free installation makes it easy to insert and secure them with a simple twist or screw, depending on the slot design.
