In the 1980s, the Ferrari Testarossa was arguably the king of the road, but what about the water? The Dellapasqua ship-builder teamed up with Modenese racing specialist Motor Service to develop a Testarossa Daycruiser for the sea, based on a glorious DC7 racing boat. Under the supervision of Ferrari engineer Mario Vincenzi, the five-litre V12 was transplanted into the Kevlar-reinforced glassfibre vessel. The result is a daycruiser that boasts some serious performance. You can currently find the boat listed for sale in the Classic Driver Market.
