This is actually a boat or a Hydrofoil that can submerge, although it’s called a Submersible Hydrofoil, that being the reason. The first of its kind. Well… actually the first kind of vehicle that can actually speed on the surface like a speed boat and truly be able to dive like a submarine. So it’s a very versatile craft that can do both! But primarily it was born as a boat that can carry 4 passengers on the surface like a speed boat and then has the capability of …diving down 50 meters of depth.
