KEY INFORMATION
COMPLETE FOIL KIT SABFOIL LEVIATHAN 1300 BLACKBIRD, MODULAR FULL CARBON
What we like
- Leviathan 1300 ultra high-aspect Front Wing: At 1330 cm² with an AR of 12.3, this is the highest aspect ratio in the Sabfoil range. It features an ultra-thin race-derived profile.
- High-cadence pumping: The reduced overall drag allows for a faster, more efficient pumping rhythm.
- Downwind Kraken SDW 360 stabilizer: With a reduced surface area of 110 cm² and an AR of 11.8, this ultra-low drag stabilizer makes for a free and agile foil.
- Integrated Active-Lift Fuselage: This design contributes to the total lift. It makes a technical profile accessible for take-off.
- Blackbird 75 mast: Made from UHM Carbon + W-Core with an FC/M modular tail, this mast provides a proven structural base.

BREAKING THE SPEED LIMIT OF PUMPING
Breaking the speed ceiling of pumping
Large wings excel at low-speed lift, but they often hit a wall when you try to accelerate. For the advanced rider, the challenge is finding a setup that doesn't just stay in flight but actively gains ground. Traditional pumping profiles create a speed ceiling induced by drag. This turns the chase for fast boat wakes or tight swells into a physical endurance struggle rather than fluid efficiency.
The Leviathan's performance evolution
The Leviathan 1300 Blackbird Kit is built around the most aggressive pumping wing in the Sabfoil range to date. The WL1300/BB pushes the high-aspect concept, refining it with a thinner, race-derived profile that thrives on speed and high-frequency movements. The radical nature of the 1300 is made accessible by the Integrated Active-Lift Fuselage. This design ensures the wing provides immediate support during take-off and dead-starts, despite its technical profile. The system is supported by the reliability of the M75/BB mast and the FC/M carbon modular tail. It is completed by the ultra high-aspect SDW360 stabilizer, a perfect match for the 1300. This offers the minimal drag needed to exploit the wing's full velocity potential.
Tech & Feel
WL1300/BB, high-speed precision: The thin, aggressive profile allows for superior cruising speed. You'll feel less resistance to acceleration, making it easier to stay in the power zone of fast wakes. Integrated Active-Lift Fuselage: The sculpted fuselage contributes to total lift. It makes the 1300's technical profile surprisingly forgiving on starts, with a clean and consistent release from the dock. SDW360 ultra low drag: Its reduced surface area gives the foil a "free" and agile feel. It rewards precise foot pressure with immediate response. High-Cadence Pumping: The reduced drag of the entire system allows for a faster, more efficient pumping rhythm. You can maintain flight with shorter, more powerful strokes. This reduces overall fatigue at high speed. M75/BB & FC/M structural base: The proven stiffness of the carbon mast and modular tail ensures that every ounce of energy is transmitted directly to the wing.
Design philosophy
The Leviathan 1300 Kit is a specialized tool for the rider who wants to move from a "glider" feel to a more reactive, speed-oriented experience. It's about merging the efficiency of a large wingspan with the sharp "bite" of a race profile. This creates a setup that transforms every pump into pure acceleration.

FAQ, SABFOIL LEVIATHAN 1300 BLACKBIRD MODULAR COMPLETE FOIL
Sabfoil designed the KL1300-FCM-SDW360-75/BB as a specialized tool for advanced riders. It delivers a more reactive, speed-oriented ride feel, moving beyond the classic "glider" feel. This complete foil is perfect for high-cadence pumping, dock-start, downwind, SUP foil, and wing foil. With its high-wingspan front wing (AR 12.3) and race-derived thin profile, this is a technical, performance-focused kit.
The Razor range focuses on glide, pumping, and downwind, with front wings from 648 to 1069 cm² (AR 8.4 to 11). It often includes Surf foil in its riding disciplines. The Leviathan range pushes the high-aspect concept further. It features larger front wings (1330 cm² for this 1300) and an ultra-thin, race-derived profile. This is optimized for pumping speed and high cadence. While the Leviathan is significantly less allround for Surf foil (not listed as a discipline), it truly excels in pump foil and downwind.
Sabfoil offers three variants of the Leviathan complete foil kit, all in Modular Full Carbon configuration: the Leviathan 1300 (this kit, €1989), the Leviathan 1400 (KL1400-FCM-SDW375-75/BB, €1999), and "The 1350-inch Leviathan (KLT1350-FCM-325-75/BB, €1999). A larger front wing wingspan means an earlier take-off.
Sabfoil uses "1300-inch as a series convention to identify the Front Wing size; however, the actual wingspan is 1280 mm, according to the specifications. This is a common practice in foiling, where model numbers do not always correspond to exact dimensions.
Yes, the kit includes all necessary components: the WL1300/BB Front Wing, Kraken SDW 360 stabilizer, Piantone Blackbird 75 mast, Carbon Rail plate with titanium inserts (CP02K/Ti), and the complete screw set and shims (MHQ02, MH144, MH137, MH160, MH171, MH172, MH107, MHW060, and MHW061). According to Sabfoil's storytelling, the kit also includes the FC/M Full Carbon modular fuselage. Only the board needs to be provided.
Sabfoil offers the Cover Mast A bag (reference MA021) for the M75/BB mast, which is compatible with the M63K, M73K, M73PLK, M75BB, and M76. For the wing, Sabfoil offers the Cover Front Wing I bag (reference MA084), explicitly compatible with the WLT1350/BB, WL1300/BB, WL1400/BB, WL1150, WL1350, WLP1060, WLP1160, WLP1260, and WLP1360.
