Most boat designs serve purposes of above-surface marine exploration, but the EGO is quite polarizing to that effect in that it can act as a submarine simultaneously.
The top of the EGO is like a pontoon boat with two large floaters on either side and a deck at the top, but everything changes once you head downstairs.
Indeed, the bottom level includes a submarine-like viewing area with massive windows on every side of the room. Thanks to the wide viewing area, occupants can see the world beneath the surface of the ocean.
As great as the EGO sounds already, it only gets better; the boat moves around with the help of electric motors, so it's a zero-emission vehicle that also happens to be friendly to the environment.
