KITTERY, Maine — Even on land, the Ghost looks futuristic and fast.
The angular vessel looks like a waterborne stealth fighter. It rides atop underwater, torpedo-shaped tubes powered by a pair of 2,000-horsepower gas turbine engines. Gyroscopes keep the ride smooth.
Sadly, Ghost is all revved up with no place to go. The brainchild of a wealthy inventor and entrepreneur, Ghost might never be a familiar household name like Humvee, Apache and Abrams — even if it works as advertised — because its creator built a warship the military isn’t convinced it needs.
“It’s a revolutionary program,” said Gregory Sancoff, founder and CEO of Juliet Marine Systems. “Nothing like this has ever been built by anybody, not even the Navy.”
He might be right: The Ghost rides on struts connected to engine assemblies he says take advantage of “supercavitation,” traveling underwater inside a bubble of gas. It’s a new application of technology that Sancoff insists will make Ghost fast — it’s so far hit about 35 mph, but Sancoff believes it can approach 60 mph — while staying stable even in rough seas.
But Sancoff has taken the usual step of sinking $15 million into a prototype that he hopes to sell to the Navy, turning upside down a process in which normally the military identifies a need before soliciting proposals and seeking funding.
“The Navy is pretty skeptical of what we’ve been working on, but they’re starting to take us more seriously,” said Sancoff, whose company operates out of a leased warehouse at the Portsmouth Naval Shipyard.
Sancoff, who as a young man raced hydroplanes, hatched his idea for the 60-foot-long vessel after terrorists using a small boat full of explosives nearly sank the USS Cole in 2000.
He thinks the Navy needs a fast patrol boat to protect larger and more costly warships when they’re most vulnerable, such as when they’re passing through the Strait of Hormuz at the southern end of the Persian Gulf. The Ghost’s smooth ride makes it an ideal platform for weapon systems — and for transporting Navy SEALs, Sancoff said.
