This is the Strand Craft 122 Open, a proposed ultra-luxurious, high-speed 38 meter yacht. If you fork over the cash to buy one you get the matching stored-aboard 880HP, twin-turbocharged V12-powered coach-built super car thrown in for free.
Strand Craft is not new to mixing cars with boats, recall the Corvette Sting Ray-inspired speeder from a few years back. But this behemoth is on a whole different scale. The Strand Craft 122 is planned as an art deco masterstroke powered by two massive MTU Series 4000 diesel engines good for over 9,200 HP and running two Rolls Royce jet drives. If that's not enough there's an optional "booster" engine in the form of a Vericor TF 50 delivering another 5,100 HP. At 38 meters with a 7.6 meter beam and 1.5 meter draft, it clocks in at 120 tons, but with so much power delivers a planned 55 knot top speed (about 63 MPH).
