FAQはこちら

While a standard submersible takes on ballast (water weight) in order to literally sink beneath the surface, a Dolphin uses its forward momentum and variable pitch diving planes to fly beneath the surface. The distinction is much like the difference between an air ship (which uses a light weight gas to obtain lift) and an airplane (which uses its wings to achieve flight).
