A ww2 PT boat did 40 knots so no improvement there then.

A hydrofoil is a type of boat with a hull rises and keeps balance out of water from a certain speed with the lift of a set of submerged wings or foils, which operate on the same principle as an airplane wing. By removing the friction drag and wave the shell, this technique can increase the speed of the boats.
