The Hyper Sub is yet another submarine designed for rich people with more time and money on their hands than they know what to do with. But hey, why not?
This model combines a speedboat with a sub, offering up a surface speed of 40 knots and a range of 500 surface miles thanks to twin diesel engines and a 525 gallon fuel tank. Once it dives down underwater, it can hit depths of up to 250 feet and offers amazing views thanks to a glass ceiling that lets you observe everything above you.
There's no price on this one yet, but it's a safe bet that mere mortals can't afford it.
