Millionaire built a futuristic warship, but now the Pentagon won’t buy it, or let him sell it abroad

Self-made millionaire Gregory Sancoff has spent a decade and US$19 million building a highly unusual stealth boat. Called Ghost, it’s designed to be faster, more stable, and more fuel-efficient than anything currently in the US Navy’s fleet of warships, he says.

“It’s such a smooth ride, you can sit there and drink your coffee going through six-foot swells,” he proudly told Bloomberg Businessweek in 2014.

But there’s a problem: The Pentagon doesn’t want Sancoff’s boat—and also won’t let him sell it abroad.
