Unleash the full power of your quad wave board. Introducing the all‑new QUAD fin set — the ultimate choice for riders who demand nothing less than uncompromising performance from their quad‑fin wave boards. Designed by Kai Hopf and based on over 30 years of experience working with the best wave sailors in the world.
Unlike generic “multi‑use” fin concepts, the QUAD set is engineered as a dedicated, no‑compromise quad system . Every outline, profile, and response characteristic has been purpose‑built for maximum control, drive, and agility in high‑performance wave conditions. This is the same design philosophy trusted—quietly but consistently—by many World Cup professionals who rely on Kai’s custom fins to stay ahead of the pack. Now, we’re making this top‑tier performance available to everyone.

Shorter fins. Higher performance.
Proof of their level of efficiency is the fact that our fins are 1–2 cm shorter than comparable quad sets. This is made possible through our exclusive AI_FIN CAD software , which achieves a flawless profile transition in the critical tip area where the fin sweeps backward. The result?
Radically enhanced maneuverability
Great grip without being sticky
Instant response in every turn
Premium materials. Maximum precision.
The center fin is CNC‑milled from black G10 , an ultra‑dense, prepreg‑laminated fiberglass material renowned for:
Outstanding durability
Exceptional impact resistance
Easy sandability to repair ground‑contact damage
This is the level of reliability and performance that serious wave sailors demand.
Choosing the right size
Select your QUAD set according to the recommendations below. Oversized fins create excessive tail lift, making your board feel sticky and harder to turn . Proper sizing ensures your board performs exactly as intended—loose, fast, and precise.
Tech Features
Super Low Aspect Design
The extra-wide design allows us to shorten the fin length as much as possible without losing surface area. This shortest possible length is the base for all air and spin moves.
ZERO FLEX & TWIST DESIGN
The ZERO FLEX & TWIST DESIGN guarantees maximum release to let you slide smoother through massive double or triple moves.
PROFILE DESIGN
The thicker refined profile results in explosive acceleration and great counter-pressure to enable maximum pop to send you flying higher.
Black G10
G10 is an extremely compressed block of prepreg laminated fiberglass sheets. This block is placed in a CNC milling machine to create the final shape and profile.
AI_Fin_3D
Our software is based on math data-driven input. Apart from being much more accurate and faster, complex 3D design tasks such as the perfect profile transition in the crucial tip area, where the fin sweeps backward, would otherwise have been impossible to realize.
TWIST DESIGN
Progressive twist for tighter radius and improved control during the turn.
FLEX DESIGN
Flexier tip for more grip and control to improve short and radical turns on the wave.
BASE DESIGN
Wide and stiff fin base for direct power transmission.
MAX EFFICIENCY DESIGN
We use our own dedicated fin 3d software. This software enables a perfect profile transition in the crucial tip area, where the fin sweeps backward.
OUTLINE DESIGN
Strongly curved leading edge for maximum maneuverability.
