Look at a Cayenne next to an original 911 and it should be immediately clear that Porsche is designing larger vehicles these days than it did in the past. Hybrids, too. But this… this is something else.

What you’re looking at is the Dynamiq GTT115, a superyacht designed by Studio F.A. Porsche (a divisions of Porsche Design). The vessel measures 115 feet from bow to stern, or roughly the length eight 718s parked end to end. It also weighs nearly 200 tons (or a hundred times more than a Panamera).

To propel all that mass through the water, Dynamiq has fitted the GTT115 with a hybrid propulsion system incorporating a pair of MAN V12s good for over 1,600 horsepower apiece with contrarotating propeller pods. With a high-speed round-bilge hull, it’ll cut through the water at up to 21 knots (or 24 miles per hour by landlubber standards).

Variable-speed generators can also power a pair of 26-hp electric motors to maneuver the boat at speeds of up to 6 knots (7 mph). Those may not seem like very high speeds for a Porsche, but they’re still a heck of a lot quicker than Porsche’s other seaside design can move.

Of course, it’ll cost you: finally launched in time for this year’s Monaco Yacht Show, the GTT115 is priced at nearly €14 million, or roughly $16.6 million in equivalent American funds – far more than initially expected, and enough to buy a tenth of the entire 911 GT2 RS production run.
