Displacement hydrofoils

Most hydrofoil designs have relatively thin bladed foils for "flying"
mode and auxiliary floats for "floating" mode.

Does anyone know of any designs that have fatter foils that make
flying more of a cross between the two modes? If so, how is the
overall performance?

Could this be an option for a long distance hydrofoil design that
wouldn't require superhuman strength and endurance?
