Windsurfing Kitesurfing Wing foil
Harness
A belt or seat worn around your waist or hips that hooks into the rig — transfers sail/kite/wing pull from your arms to your core.
Also known as: waist harness, seat harness
A harness is the single biggest endurance multiplier in wind sports. Instead of holding kilonewtons of pull through your arms and grip strength, you hook a metal bar (the hook) into a loop on the rig (kite chicken loop, windsurf harness lines, wing harness loop) and let your skeleton take the load.
Two main types:
- Waist harness — sits on the lower ribs, more freedom of movement, standard in kite, wing and most freestyle windsurfing
- Seat harness — wraps around the hips and thighs, more comfortable for long slogging sessions, common in beginner windsurfing and big-wave kite
Fit matters: a harness that rides up under the ribs ruins a session. Spend on a decent harness early; it’s gear you use every minute on the water.

- Depower Reducing the angle of attack on a kite to dump power — done via the chicken loop or trim strap.
- Planing When a board rises out of the water and skims across the surface instead of pushing through it — the threshold that turns slogging into flying.
- Footstraps Adjustable straps mounted on the board that lock your feet in once you're planing — control, leverage and air time depend on them.
