Description.

Whether you’re just starting out or you’ve been paddling for years, the Longboard SUP brings a timeless, smooth feel to every session. Designed for everything from peaceful flat water paddles to stylish nose rides on mellow waves, this board blends classic surf style with modern performance.

Its shape gives you the freedom to cruise, carve, or even hang ten with ease. You can set it up as a single-fin for that classic glide, or as a tri-fin for more control and turning power. The soft, rounded rails make it forgiving when you’re learning new moves or just want a smooth ride. If you’re after a board that can do it all—from chill beach days to stylish surf sessions—this one should be at the top of your list.

Kai Lenny & his Sup Collection by Quatro. A new era begins.

Two movements took shape on Maui’s North Shore in the early ’90s. Kai Lenny — destined to become the most versatile waterman on the planet. Forward Maui — the creative force behind Quatro and KT Surfing.

A Shared Vision.

From towing into monster waves, riding remote reef breaks, competing internationally, traveling and exploring all the waves this world has to offer then back to spending hours tweaking designs and shaping in the factory – Kai and Keith have forged a shared pursuit: to transcend boundaries in Surfing, Tow-in, Windsurfing, Sup, Kiting and Foiling. The result is relentless innovation – driving the future of board design.

Kai started surfing at 4, windsurfing at 6, Sup at 7, and foiling / tow-in by 9. He’s spent a lifetime redefining what’s possible across every discipline.

Kai Lenny: “Since 2019, Keith has shaped every board on the face of the planet under my feet. All these sports feed into each other. The more time I spend on the water, no matter the medium, the better I get — and the more fun I have.”

Since 1994, Keith Teboul has been pioneering construction and shaping from his home in Haiku, Maui, the ground zero for global wave and wind innovation. The legendary shaper of Quatro and KT, translates Kai’s unfiltered feedback into ever-evolving custom boards, spanning everything from Jaws, Mavericks, and Nazare to Ho’okipa, Indo, and the North Shore of Oahu. Now, that synergy is opening its doors.
