Foils


The weight a foil can lift is proportional to its lift coefficient, the density of the fluid, the foil area and its speed squared.
They geniality of Catbark foil solution, is that it is twisted into the water. Hereby make the area amount of foil increase as it enters and again diminish as speed increase.
Traditional foils are normally lowering down directly from the hull and thereby creates a constant factor of drag, that of the full foil.
Also, as proven by the America Cup AC 75s solutions where one leg is in and the other leg is out and the aft foil on the rudder, creates a three legged situation of unstableness, besides being “delta wings “ , and thereby need a certain speed to stay up.
