Technically speaking, these are a large fin, but when ridden as a thruster set up, they surf smaller than they actually are, enabling them to be used on a wide range of boards by most riders. As a quad set up, the upright rear fins act as a pivot, allowing you to turn tighter than you normally would with a standard quad set.

Material: Carbon - Carbon fibre base for drive and response.

  • Foil: Side Fins: Flat - Flat inside foiled fins are better for maintaining control at speed. The preferred fin in powerful surf where speed isn't an issue. Flat foiled fins will feel closest to glass ons.
  • Rears: Symmetrical - The rear fins have symmetrical foil which offers a versatile, fluid and consistent feel when used as a quad set.. Suited for all conditions.
