Comment on Ghost: Stealth Attack Hydrofoil Uses Supercavitationparent

It also reminds me of this Canadian invention: http://en.wikipedia.org/wiki/HMCS_Bras_d'Or_(FHE_400)

Ya, but that ship was an actual hydrofoil. The foils act like wings to generate lift from movement. The thing in the OP uses movable pontoons, buoyancy, to haul itself up regardless of speed.

Note also that real hydrofoils angle their foils in parallel to the hull. It's essentially a dihedral effect like that of an airplane. As the ship lists one way, the foil on the downward side pushes more directly upwards, righting the ship. The 'foils' on the OP are mounted in the opposite manner, generating opposite effect. If they generated any actual lift the ship would flip instantly.
