Foil surfboards are designed with a hydrofoil under the board that lifts the board out of the water, allowing for a smoother and faster ride. They're a popular choice for experienced surfers looking for a new challenge and a different kind of wave-riding experience.

Foil surfboards are a new innovation in surfing that allow you to "fly" above the water's surface. They are similar to a standard surfboard, but have a hydrofoil attachment underneath that lifts the board and rider out of the water. This design allows for greater speed and manoeuvrability, making it a popular choice among advanced surfers looking for a new challenge. However, foil boards require more skill and experience to ride safely than traditional surfboards, so it's important to get proper training before trying one out.
