Hydro- foils are becoming more familiar in the Multihulls, every year catamarans and trimarans are having foils added or designed into there structure. Foils are a low cost development that increases performance by up to 40%. Racing Multihulls have been utilizing the lifting abilities by of a foil by incorporating the lift into there dagger boards by angling the boards so they produce lift. We go one step farther and make a horizontal foil that reaches across the tunnel of our catamarans. We use a high lift foil to generate maximum lift between 10 to 35 kts.
