When you're fed up with a Ferrari and the Lamborghini has lost its lustre, the Strand Craft SC122 super yacht is just the tonic for bottomless-pocketed supercar lovers.

Yes, we know the SC122 is a super yacht, but it comes with the ultimate accessory, and we don't just mean its cavernous car-swallowing below-decks garage.

What we're referring to is the one-off 880bhp supercar that you can only order if you buy one of the £100 million 122-foot yachts.

Packing a twin-turbo V12 engine, the supercar has been designed by Eduard Gray and snuggles in its very own water-tight garage on the yacht. There's a custom-built ramp to get the car off the boat and on to dry land, so lucky owners can make the most of its performance when moored up.

Built from carbon fibre, the 1,182kg supercar has a claimed top speed of 234mph and cracks 0-62mph in just 3.2 seconds.

However, the supercar's performance statistics pale next to the SC122's, which has twin Rolls-Royce engines that each produce 4,610bhp. They give the SC122 a top speed of 55 knots when coupled to the optional 5,100bhp Rolls-Royce waterjet booster.

The sleek design of the SC122 is matched by an Art Deco-inspired cabin that boasts four double bedrooms, a stateroom and a salon, as well as space in the garage for its own bespoke tender.
