We offer the fins exclusively as a complete set because they were engineered to work in perfect harmony — exactly as Kai intended.

While other brands rely on compromise designs that need to work across multiple setups (single, tri/thruster, quad), the TRI fin set is different. It’s a no‑compromise, high‑end solution created to meet — and exceed — the expectations of World Cup‑level riders. In fact, it’s an open secret that many of the sport’s top professionals have been relying on Kai’s custom fin designs for years. Now, that same elite performance is available to every rider.

Shorter fins. Higher performance.

One of the key indicators of their efficiency: our fins are 1–2 cm shorter than comparable tri/thruster sets. This is made possible through our exclusive AI_FIN CAD software, which creates a flawless, highly efficient profile transition in the critical tip area where the fin sweeps backward. The benefits?

  • Radically improved maneuverability
  • Excellent grip without any sticky feeling
  • Instant, precise response in every turn

Premium materials. Maximum perfection.

  • The center fin is precision CNC‑milled from black G10, an ultra‑dense, prepreg‑laminated fiberglass block. G10 is the ideal choice for medium-size maneuver center fins.
  • The side fins are injection molded using our exclusive CARBO_TECH material to ensure the necessary tip flex despite the short length.

This is the level of quality and consistency that serious wave sailors expect.

Choosing the right size

Select your TRI set according to the recommendations below. Oversized fins generate excessive tail lift, making your board feel sticky and harder to turn. The correct size ensures your board performs exactly as intended — loose, fast, and precise.

Worked twice then died within 3 months
Color: 7-in-1 Silver & Black/Beer Opener, Size: Rechargeable Set
The set is nice, looks good, well organized. The features are simple and the main opener looks and feels sturdy. However, roughly half the corks just get torn and don’t extract. Had 3 or less successes with as many failures. We only drink a few bottles a month at most. Now the unit just completely stops almost as quickly as it starts. You can reverse the screw to get it out when it stops and the motor seems fine when not pressed against a bottle/cork. The way it stops almost immediately when fully charged and cool means it isn’t an overheating issue or weak battery issue from what I can tell. Very disappointed and wished I’d returned it the minute I had the first issue. I thought it might just be me not holding it firmly enough or needing to learn some trick, but it was definitely the unit going bad. Buyer beware.

Easy to operate.
Color: Black/Battery
Very easy to operate. I was a little confused on how it operated but all I had to do is sit it on top of the can and it operates by itself. When it is done, the lid can be removed or set on top of the can. It doesn't leave any sharp edges. I was using a hand held one but because I have arthritis in my wrist, it is worth the price easy enough for seniors or disabled

Only worked for 1 month.
Color: Black/Battery
This product was delivered on April 20th and worked great. It made a nice clean cut in the metal with no sharp edges and the top of the can lifted up nicely. Yesterday, May 24th, it stopped cutting and unfortunately, the return window closed on May 20th.
