KL1400-FCM-SDW375-75/BB - Kit Leviathan Blackbird 1400-SDW375-75 - Modular Backtail

Breaking the Resistance of Distance

For the dedicated pump foiler and downwind enthusiast, the enemy isn't just gravity—it's drag. Traditional large-surface setups often lack the "legs" to bridge long gaps between swells or the speed to stay locked onto a fast-moving boat wake. To achieve true "infinite glide," you need a system where every component is tuned to minimize turbulence while maximizing forward momentum. You don't just want to stay up; you want to travel.

A Synergetic Performance Ecosystem

The Leviathan 1400 Blackbird Glider is a complete high-performance set designed for one purpose: ultra-efficient displacement. At its heart is the WL1400/BB Front Wing, featuring its radical race-inspired profile and the Integrated Active-Lift Fuselage. This design ensures that even a technical, high-speed wing remains accessible during take-off.

To translate this efficiency into control, the set includes the Modular Carbon Back Tail (FC/M). This full-carbon extension provides the "granitic" torsional stiffness required to handle the massive 1400mm wingspan without unwanted flex. Completing the setup is the SDW375 Stabilizer, specifically engineered for pumping and downwind. Its low-drag geometry offers the perfect balance of pitch stability and yaw freedom, allowing you to "pump" with less vertical oscillation and more horizontal drive. Finally, the M75/BB ultra-high modulus mast with W-Core technology ensures a direct connection between board and hydrofoil for the best performance.

Tech & Feel

• WL1400/BB - Radical Glide Engine: The front wing’s extreme aspect ratio and thin profile provide a frictionless sensation. You will feel the foil "slipping" through the water, allowing you to maintain cruise speed with minimal physical input.

• Active-Lift Integrated Fuselage: The built-in lifting profile of the front wing's fuselage makes Dead Starts more consistent. It provides that crucial "pop" off the dock, getting you into the flight zone with less effort while keeping performance.

• FC/M Modular Carbon Tail: The full carbon construction ensures immediate power transfer. Every pump is transmitted directly to the wing with zero lag, resulting in a reactive and precise feel underfoot. And you can trim and tune any stabilizer with shims thanks to the modularity!

• SDW375 Downwind Stabilizer: Specifically made for efficiency. It offers long-range stability in downwind conditions while remaining small enough to stay out of the way during high-cadence pumping.

• Surgical Maneuverability: Despite the impressive wingspan, the combination of the refined wingtips and the optimized stabilizer allows for fluid transitions and carving, making it easy to stay in the "power zone" of a wake.

The Design Philosophy

The Leviathan 1400 Glider set is the bridge between technical racing hydrodynamics and the soul of surfing. We have taken our most advanced carbon technologies and combined them into a package that turns every body of water into an infinite playground. It is a high-performance tool for the rider who views foiling as a journey, not just a sport.
