When used as a lifting element on a hydrofoil boat, a new kayak design, called flyak, has hydrofoils that lift the kayak enough to significantly reduce drag,. Hello everybody, i have been designing a hydrofoil lately and have tried to optimize it for the lift over drag ratio. up to this point, i have only.... Hydrofoil design. hydrofoils are wing-like structures which are mounted on struts below the hull of the sailing structures, which can vary from small boats to big passenger boats..
The function of hydrofoils is to lift the entire hull of a boat above the surface of the water. since the hull of the craft is not in direct contact with the water an increase in speed can be expected of a boat and motor combination by at least 25%.. This gravity-defying us$40k catamaran rises completely out of the water at speed on a pair of hook-shaped hydrofoils. it looks like the work of david copperfield, but it’s real, and it’s set to start a revolution in the sailing world.. The hightech catamarans that are competing nowadays in the america's cup don't have anything in common with ordinary boats. the so-called "hydrofoils" allow.
