Cool Concept: Scubacraft Submerges You in the Sea (8 photos)

The brainchild of engineers and entrepreneurs from Wales, Scubacraft is the first self-contained submersible that's also a capable surface watercraft.

Scubacraft uses an internal-combustion engine to reach a dive site where it can descend to a maximum depth of about 100 feet. "The experience is simply exhilarating," Scubacraft sales and marketing director James Browne says. "Nothing else can compare to traveling to a dive site at 50 mph, and then powering effortlessly under the water."

It's not a pressurized submarine, which means that those on board must wear scuba gear before submersion. With no cranes needed to lower the craft below water and no boat needed to carry it out to sea, Scubacraft is significantly more versatile and less expensive than similarly sized submarines. Scubacraft is rumored to cost around $164,000.
