BREAKING THE RESISTANCE OF DISTANCE
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 cover long distances between waves or the speed needed to stay in a fast boat wake. To achieve 'infinite glide,' you need a system where every component is tuned to minimize turbulence while maximizing forward momentum. The goal isn't just to stay flying: it's to travel.
A Synergistic Performance Ecosystem
The Leviathan 1400 Blackbird Glider is a complete high-performance set designed for a single objective: ultra-efficient displacement. At its heart is the WL1400/BB front wing, with its radical race-inspired profile and the Integrated Active-Lift Fuselage that ensures even a technical, high-speed wing is easy to get flying. To translate this efficiency into control, the set includes the Modular Carbon Back Tail FC/M, whose full carbon extension provides the granite-like torsional stiffness needed to manage the 1380 mm wingspan without unwanted flex. The SDW 375 stabilizer completes the setup, specifically designed for pumping and downwind. Its low-drag geometry offers the perfect balance between pitch stability and yaw freedom, allowing you to pump with less vertical oscillation and more forward drive. Finally, the ultra-high modulus W-Core M75/BB mast ensures a direct connection between the board and the foil.
Tech & Feel
WL1400/BB, radical glide engine: The extreme aspect ratio and thin profile of the front wing offer a 'frictionless' feel. The foil glides through the water, allowing you to maintain cruising speed with minimal physical effort. Active-Lift Integrated Fuselage: The integrated lifting profile in the fuselage makes dead-starts more consistent, providing the crucial 'pop' to leave the dock. FC/M Modular Carbon Tail: Full carbon construction for immediate power transmission. Every pump is transferred directly to the front wing without delay, and modularity allows you to test other stabilizers and adjust the trim with shims. SDW375 Downwind: Specifically designed for efficiency, it offers long-range downwind stability while remaining compact enough not to hinder high-cadence pumping. Surgical maneuverability: Despite the impressive wingspan, the combination of refined wingtips and the optimized stabilizer allows for fluid transitions and natural carving, helping you stay in the 'power zone' of a wake.
Design Philosophy
The Leviathan 1400 Glider is the bridge between technical race hydrodynamics and the soul of surf. Sabfoil has combined the most advanced carbon technologies into a package that transforms every body of water into an infinite playground. It's a high-performance tool for the rider who sees foiling as a journey, not just a sport.

FAQ, SABFOIL LEVIATHAN 1400 BLACKBIRD MODULAR KIT
Sabfoil presents the KL1400-FCM-SDW375-75/BB as a high-performance set for the committed pump foiler and downwind enthusiast seeking ultimate efficiency in motion. The "glide engine" profile with its extreme aspect ratio and 1380 mm wingspan makes it the top light-wind Leviathan option, able to take off in just 7-9 knots. It covers five disciplines: Wing, Surf, Pump foil, SUP foil, and Downwind.
Both Leviathan kits share the same M75/BB mast, the FC/M modular fuselage, and a race-derived profile (AR 12.3). The key difference lies in the front wing and stabilizer. The 1300 model features a 1330 cm² front wing (1280 mm wingspan) and a super low-drag SDW 360 stabilizer (110 cm², AR 11.8). This 1400 kit, however, comes with a 1549 cm² front wing (1380 mm wingspan) and a more versatile SDW 375 stabilizer (130 cm², AR 10.4). While the 1400 offers an earlier take-off (7-9 knots vs. 10-12 knots), the 1300 has a higher top speed (19-21 knots vs. 16-18 knots). The 1400 also expands your riding options by adding Surf foil to its disciplines.
Sabfoil uses "1400" as a naming convention to identify the front wing size. The actual wingspan is 1380 mm, as detailed in the specifications. This same convention applies to the 1300 model, which has an actual wingspan of 1280 mm.
Sabfoil offers three distinct variants of the Leviathan kit, all in a Modular Full Carbon configuration: the Leviathan 1300 (KL1300-FCM-SDW360-75/BB, €1989, the fastest option), the Leviathan 1400 (this kit, €1999, designed for the best light wind performance), and "The 1350" Leviathan (KLT1350-FCM-325-75/BB, €1999).
Yes, this kit includes every essential component you need: the WL1400/BB front wing, the FC/M Full Carbon modular fuselage, the Kraken SDW 375 Downwind stabilizer, the Piantone Blackbird 75 mast, and the Carbon Rail plate with titanium inserts (CP02K/Ti). You also get the complete screw set and shims (MHQ02, MH144, MH160, MH164, MH171, MH173, MHW060, and MHW061). All you need to provide is your board.
Sabfoil offers the Cover Mast A bag (product code MA021) for the M75/BB mast, compatible with M63K, M73K, M73PLK, M75BB and M76. For the front wing, the Cover Front Wing I bag (product code MA084) is specifically for WLT1350/BB, WL1300/BB, WL1400/BB, WL1150, WL1350, WLP1060, WLP1160, WLP1260 and WLP1360.
