Combining a performance hull with a luxury topside can be tricky since most yacht builders can either do one or the other, but rarely both. Bladerunner’s new 45 GT, premiering at Cannes from Ice Marine in the UK, accomplishes both missions. The 45-footer reaches a top end of 50 knots, thanks to its stepped hull, designed to funnel air so it lifts the boat higher over the water, and triple 370 hp D6 Volvo Penta engines. The GT designation, standing for Grand Tourer, kicks in above the waterline, with a big sunbed on the open stern, enclosed social area in the cockpit, and a very generous cabin below. The Bladerunner has GT-like features rarely seen on any yacht, including electric side windows, suspension seats for rough-water running, and a superyacht’s electronics package. Belowdecks, plenty of natural light fills the contemporary cabin, thanks to overhead glass panels and side windows. If 50 knots is just not enough, Ice Marine can up the speed to 70 knots (80.1 mph) for “specialist” applications.
