- Hand wing for a 75 to 85 kg rider: about 5.5 to 7 m² in 10 to 14 knots, 4.5 to 5 m² in 15 to 20 knots, 3 to 4 m² above 20 knots.
- Front wing: beginners 1600 to 2200 cm² (low to mid aspect); intermediate 1100 to 1500 cm²; advanced 700 to 1000 cm².
- Mast: 70 to 75 cm for learning and shallow water; 85 to 90 cm for chop and swell.
- Minimum wind: most riders can foil from about 10 to 12 knots with large gear; 15 to 20 knots is the comfortable range.
