The TF10 hydrofoils are daggerboards in a so-called Z-shape.
The rudders are foils with a T-lifting surface.
The TF10 is a 4-point foiling boat. This configuration ensures that you always sail with all four foils down.
This 4-point line-design has its origin in the DNA F1x. DNA was the first to find a solution to get the A-class upon the foils whilst complying with all special boxrule restrictions for that class.
The design of the TF10 foils comes from Morrelli & Melvin.
