IQFoil

IQFoil is a type of sailing boat designed for racing. It uses a 'foil' (or fin-like shape) underneath the hull of the boat, which helps it to move faster through the water. It's like having wings on your boat! The wings create lift and help to reduce the amount of drag caused by the water, making the boat move more quickly. When the boat is tilted, the lift from the wings also helps the boat to turn more quickly. IQFoil boats are used in competitive sailing races all around the world.
