Description

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.
