Kaohi Double Coil Ankle Leash-Blue-6' x 8mm

The Kaohi Double Coil Ankle Leash (6' x 8mm) is a heavy-duty foil leash built by Kaohi, a Hawaii-based company operating out of Honolulu since 1993. Designed specifically for foiling disciplines — wing foiling, prone foiling, SUP foiling, and downwinding — this leash uses a double coil configuration to address common problems with standard coil leashes in foil setups. The 8mm cord provides durability suited to higher-load conditions, while the double coil format keeps the leash compact and out of the water during use.

A distinguishing feature is the patented Grip rail-saver handle (US Patent 10,737,750 B2), a neoprene-covered grip positioned along the leash that stays open and accessible. This handle gives riders a way to keep the board close between sets, manage the board in whitewater, and assist with pulling the board onto docks or jet skis.

This leash targets intermediate to advanced foilers who need a reliable tether that won't interfere with their foil setup. Standard coil and straight leashes tend to wrap around mast and fuselage assemblies during wipeouts, creating retrieval hassles and potential gear damage. The double coil design reduces that tangling behavior while maintaining enough stretch to give riders separation from the board during falls.

The 8mm cord thickness makes this the heavier-duty option in Kaohi's double coil range, suited for riders in more demanding conditions or on larger boards. Riders on smaller boards in calmer water who prioritize minimal drag may prefer Kaohi's thinner 5.5mm double coil variant. The ankle cuff fits riders who prefer a lower attachment point; Kaohi also offers a calf cuff version for those who want the leash connection higher on the leg to reduce foil entanglement further.

Within Kaohi's own range, the Double Coil leash line spans two cord thicknesses — 5.5mm and 8mm — and comes in both 6' and 7' lengths with ankle or calf cuff options. The 8mm version sits as the heavy-duty choice, while the 5.5mm targets prone foilers and lighter-wind riders who want less weight and drag. All versions share the patented Grip handle and double coil architecture.

In the broader foil leash market, the Kaohi competes with options like the Dakine Kainui and various generic coil leashes adapted from SUP use. Where most competitors offer single-coil or straight cord designs, the double coil format is Kaohi's primary differentiator, aiming to solve the specific tangle and drag issues that foilers encounter. At $54 for the 6' x 8mm ankle model, it sits in the mid-to-upper price range for foil leashes.
