One-Lock Carbon Mast

The Slingshot One-Lock Carbon Mast is a mid-to-high modulus carbon foil mast built around Slingshot's modular One-Lock connection system. Available in 72 cm, 82 cm, and 92 cm lengths, it sits in the middle of the brand's mast hierarchy — stiffer and lighter than the One-Lock Aluminum Mast, while offering a more accessible price point than the HM Carbon and Pro HM Carbon options higher in the range. The mast uses a hollow-core construction with a tapered chord profile that measures 118 mm at the foot and widens to 145 mm at the base, a shape intended to balance hydrodynamic efficiency with structural rigidity. Trailing edges are hand-finished to reduce vibration and promote cleaner water flow.

Slingshot includes an RTS (Rapid Tool-free Setup) mounting kit and a protective cover with each mast. The multi-hole top plate accepts bolts without requiring T-nut alignment, and the mast supports three mounting configurations: flush mount, T-Lock mount, and RTS mount. Internal connections between the mast and wing components keep junction seams away from direct water contact, which helps minimize turbulence at those joints.

The One-Lock Carbon Mast targets intermediate riders stepping up from aluminum equipment. If you've been foiling on a Slingshot aluminum mast and want noticeably more stiffness and responsiveness without jumping to the top of the price ladder, this is the intended upgrade path. The added rigidity from the carbon layup translates to more direct feedback underfoot, which supports progression into carving, tacking, and other maneuvers that demand precise input.

The three length options cover a useful range of ride heights. The 72 cm suits riders who prefer staying close to the water or who foil in shallower conditions, while the 92 cm provides additional clearance for swell and chop. The 82 cm length serves as a versatile middle ground for most conditions. Because the mast works within the One-Lock ecosystem, it pairs with Slingshot's wing and stabilizer families across disciplines — wing foiling, kite foiling, wake foiling, and dock-start or pump foiling setups.

Slingshot's current One-Lock mast range runs four tiers deep. The Aluminum Mast anchors the entry level, built from 6061-grade aluminum for durability at a lower cost. The Carbon Mast reviewed here occupies the second tier, adding meaningful stiffness and weight savings. Above it, the HM Carbon Mast (priced from $1,429 for the 72 cm) uses a higher-modulus carbon layup for riders who prioritize maximum stiffness and direct feedback. At the top sits the Pro HM Carbon Mast, a longer 102 cm option with a redesigned low-drag profile aimed at performance-focused riders chasing speed and efficiency across a wider range.

For buyers comparing across brands, the One-Lock Carbon Mast competes in the mid-range carbon mast segment — above budget aluminum options but below premium full-high-modulus offerings. Its modular One-Lock interface and tool-free RTS assembly differentiate it from masts that require conventional bolt-up at every session.
