Kaohi Downwind Double Coil Calf Leash-Orange-7' x 8mm

The Kaohi Downwind Double Coil Calf Leash is a heavy-duty foil leash built around an 8mm double-coil polyurethane cord and a 7-foot stretched length. Kaohi — Hawaiian for "control" — is designed in Encinitas, California, and distributed through Board Meeting USA. The brand focuses exclusively on leashes for foiling and surf disciplines, and the Double Coil 8mm line is their workhorse option for riders who need reliable hold in demanding conditions. This particular configuration pairs the 7-foot cord with a 1.5-inch neoprene calf cuff, positioning it as the longer-reach option in the Double Coil family.

The defining design element across the Double Coil range is the patented Grip — a rail-saver handle integrated into the board-side attachment. The Grip lets riders grab the leash near the tail to keep the board close during water starts, lulls between sets, or when navigating crowded lineups. The double-coil construction addresses a common complaint with single-coil foil leashes: kinking and tangling. By running two parallel coils, the leash resists twisting on itself, reduces drag by staying above the waterline, and minimizes the chance of snagging on the mast or fuselage during a session. Swivels at both ends further reduce line twist.

The 7-foot, 8mm Double Coil targets intermediate to advanced foilers who ride in conditions where a heavier-gauge cord is warranted — open-ocean downwind runs, larger surf, or choppy wing foil sessions where wipeouts put real load on the leash. The 8mm diameter provides more tensile strength than the thinner 5.5mm Double Coil variant that Kaohi offers for lighter-duty wing and board use. Riders doing downwind foiling, prone foiling, wing foiling, and SUP foiling are all within the intended user base.

The calf-mount position keeps the attachment point higher on the leg, which helps the coiled cord clear the water surface and stay away from the hydrofoil assembly. Riders who prefer a lower connection point can opt for the ankle-cuff version in the same 7-foot, 8mm spec.

Within Kaohi's own catalog, the Double Coil 8mm sits as the heavy-duty tier. Below it, the Double Coil 5.5mm is a lighter, thinner option geared toward wing and board leash duties where extreme holding power is less critical. Above — or rather alongside — sits the Kaohi INVIZ, a hybrid leash combining a short polyurethane coil section with a marine-grade bungee cord for a dramatically lighter package (roughly 4–6 oz versus the heavier 8mm coil). The INVIZ is purpose-built for downwind foiling where minimizing weight and noise is the top priority, while the Double Coil 8mm trades some weight savings for raw durability and the integrated Grip handle.

The 7-foot length is one step up from the 6-foot Double Coil 8mm, which retails for slightly less. Riders on longer boards or those who want extra separation between themselves and the foil after a fall typically choose the 7-foot option. Compared to competing foil leashes from brands like Dakine or Ocean Rodeo, the Kaohi's double-coil layout and patented Grip handle are its primary differentiators.
