And when you open her throttle, she really does fly through the water, with a colossal top speed of 55 knots.

Of these, five are fitted with a Vericor gas turbine combined with a central booster, generating an extra 5,100hp. This allows them to reach 55 knots compared to 40 knots in the standard model.

Launched in 2005, Mistral 55 (pictured above) was the third hull in the series and the first to feature the gas turbine, but the fastest recorded speed in the Pershing 115 fleet belongs to another 2005 launch, Azzam.

And when you're not blasting along at top speed, the four spacious cabins mean there's plenty of room for eight guests to relax.
