The foil glossary
Mast
The vertical piece connecting the board to the fuselage. Determines flight height. Standard: 70 cm (beginner), 75–85 cm (all-around).
Front Wing
The main lift generator. Surface area (cm²) and aspect ratio define take-off ease, speed and glide. MA = entry/freeride, MHA = versatile, HA = glide/downwind.
Fuselage
The horizontal bar linking front wing to stabilizer. Shorter = tighter turns (freestyle). Longer = better tracking (downwind).
Stabilizer
The small rear wing that balances the foil in flight. Larger = more stability. Smaller = looser, more responsive.
Aspect Ratio
Wingspan² ÷ surface area. Low AR (≤6): compact, maneuverable, forgiving. High AR (≥8.5): fast, efficient glide, better upwind. Medium AR (~7): versatile all-around.
Aluminium & Carbon
Aluminium: affordable, impact-resistant, ideal for learning. Carbon: lighter, stiffer, earlier take-off, more responsive. Best for intermediate+ riders.
Disciplines
Freeride: everyday riding, cruising, progression. Freefly: riding swell with the wing flagged. Wing Surf: waves with the wing in hand. Freestyle: jumps, rotations, tricks. Racing: speed on a course.
Pumping
Leg-driven motion to generate or maintain speed without wind or wing propulsion. Essential for dock starts, connecting waves, and downwind glides.
Jibe & Tack
Jibe: downwind turn, changing direction with the wind at your back. Tack: upwind turn, passing through the wind.
Stall
Loss of lift causing the foil to sink. Happens when speed drops below the foil's minimum flight speed (typically ~5 knots).
