The largest water sports fair in the world - the Boot in Dusseldorf - just closed its gates. It took place under the motto: Everything foils - windsurfing, kiteboarding or sailing. Foil conquers the waters from the Müritz to Hawaii. The only ones who stay behind are the SUP paddlers, but nothing is impossible - we still think that they can do it one day.
Foil is a thin sheet of metal - a foil of metal. It is a kind of thin fin/centerboard that is below the underwater ship of the boat or below the windsurfing or kitesurfing board on which you sail or surf. This reduces friction and resistance of the boat or board. It allows us to glide or - better said - to foil with little wind.
