Hyper-Sub - World's First Powerboat that Turns into a Submarine
Having the goal of combining the possibilities of a submarine and a heavy-duty, surface-cruising powerboat, a company called Marion Hyper-Submersible Powerboat Design created Hyper-Sub.
The powerboat that can turn into a submarine to allow its driver and on-board guests to enjoy the underwater world, can reach the top speed of 75 knots per hour on top of the water, with its engine being able to generate power of up to 880hp.
The 31-foot powerboat can submerse 250 feet under water and is the world's first small vehicle that can transform into a self-charging, autonomous, one-atmosphere submarine.
