1. A hydrofoil vehicle, comprising in combination:
a substantially rigid frame having a front section and a rear section, the front section being forward of the rear section in a longitudinal direction;
a front foil connected beneath said front section of said substantially rigid frame;
a rear foil connected beneath said rear section of said substantially rigid frame;
said front foil and said rear foil each having an elongate form extending laterally relative to the longitudinal direction, and with a foil shape and orientation which causes lift when moving forward through water;
a propeller located beneath and supported by said substantially rigid frame, said propeller powered by a power source carried by said substantially rigid frame;
said power source includes pedal cranks rotatably coupled to said propeller to power said propeller as said pedal cranks rotate, said pedal cranks adapted to be rotated by a human rider carried upon said substantially rigid frame,
said propeller coupled to said power source through a drive train therebetween, characterised by said propeller extending forward from portions of said drive train adjacent to said propeller.
