To match its explosive looks, the 63 has twin 2,000-horsepower MAN V12 diesels that give it a blistering top end over 60 knots, and a fast cruise of 40 knots. That is true go-fast-boat territory, and a number worthy of the Lamborghini pedigree. The yacht’s performance credentials are further strengthened by a GRP hull and loads of carbon fiber in the superstructure. The use of the lightweight material up top pulls double duty. It helps maintain the boat’s low center of gravity for stability in a seaway, and also keeps her in fighting shape, at a feathery 24 tons.
