ABSTRACT:
A passively controlled hydrofoil supported planning watercraft having a conventional hull with an integrally formed step. The watercraft includes a centrally located, fully submerged main lifting foil. The main lifting foil is fixed and non-movable, and is attached to the hull along the centerline keel such that its line of action acts substantially through the longitudinal center of gravity of the watercraft. The watercraft further includes a rearwardly located stabilizing foil fixed to a stabilizer strut which is pivotally attached to the stern of the watercraft. A stabilizer strut so attached pivots fore and aft to control watercraft trim angle. Additionally, the stabilizer strut is rotatable about a substantially vertical axis for steering and roll control, and includes a trailing edge upper rudder for yaw control.
