We shall not go into technical details, but only on the role of each different parts of the foil.
The box will connect the foil to the board via one or more screws. There are different types of boxes with each of the advantages and disadvantages that you will find in this article.
The Mast is one of the most important parts of the foil, in fact many of its characteristics will influence the foil's behavior. In summary there are 3 sizes of mat:
- short mast (- 60 cm) intended only for schools, their low height greatly reduces falls and promotes learning. After 1 to 2 hours of training, this length of matt is no longer interesting.
- medium mast (- 90 cm) this mast length is the most used because it corresponds to a versatile use - Freeride.
- long mast (more than 100 cm) intended only for the race, the masts of more than 100 cm, even to 115 cm for some, make it easier to cross the waves and allow a better upwind angle.
The fins of a foil function exactly as the wings of an airplane, they serve for the lift and maneuverability of the foil.
The explanation of the phenomenon of hydrodynamic lift can be partially given, by the variation of velocities of the fluid, between the intrados and the extrados. This variation in velocity (the particles traveling on the extrados go faster than those on the intrados due to the greater distance) causes a pressure variation which generates the lift.
