The Hyper-Sub Submersible Powerboat is a vessel that is capable of operating as a boat or a submarine. Built by Marion Hyper-Submersible Powerboat Design, the Hyper-Sub's creator, Reynolds Marion, enlisted his young, mechanical engineer next door neighbor to help him develop the first hybrid of this variety. The big difference here is that the sub works as a surface vessel while also allowing for horizontal movement, a lot like a helicopter does.
