Typhoon is an open source free and easy to use software in which you can calculate any hydrofoil design. You get:

  1. static force and moment calculation giving you forces, moments, as well as the overall lift and drag you get for a predefined forward speed, trim and elevation.
  2. static equilibrium calculation (Newton Rhapson) gives you the trim and elevation which results in an equilibrium vertical force and moment around Y (external forces are assumed to be constant). For example, if more lift is needed for your mass, the trim will increase and/or your foils go deeper in the water (resulting in higher lift forces). The forces and moments you get are net forces so almost zero.
  3. stability matrix indicating if the foiling ship is stable: If you give it a kick will it return to an equilibrium or get a nice splash? You need to like eigen values.

Happy foiling!
