Speedboat and submarine in one.
How would you like to have your very own speedboat? What about a submarine? What if you could have both of those things in the one amazing vessel? You can with Hyper Sub. As a speedboat, the Hyper-Sub can easily travel long distances and has a cruising speed of 38 mph. It can also deep dive while providing protection for its crew from changes in pressure. Imagine the possibilities for exploration and adventure that could be found above and below sea level.
