The Grand Banks Yachts’ GB60-03, powered by a pair of Caterpillar Marine’s Cat® C12.9 supercharged and turbocharged diesel engines, has completed sea trials.
Featuring a length of 19.9 meters and a draft of 1.4 meters, the GB60-03 achieved a top speed of 33 knots during the trial.
Caterpillar Marine informed that the common rail C12.9’s installed in GB60-03 are capable of delivering 1000mhp@2300rpm while meeting EPA Tier 3, IMO II, EU Stage IIIA and RCD emission requirements.
The C12.9 propulsion engine has an electronically controlled supercharger that allows for torque and throttle response at low speeds while maintaining fuel efficiency at high speeds, while the common rail system provides quiet, controllable fuel delivery allowing for more complete combustion thus lowering fuel consumption and smoke.
In addition to supplying the engines, Cat dealer Tractors Singapore Ltd. also supplied a pair of 7″ Cat Marine Displays for the salon and a pair of 7″ Cat Marine Displays at the flybridge.
“The new GB60 features a beautiful design with a ride that easily surpasses any yacht of its size on the water today,” YP Wong, engineering director for Grand Banks Yachts, said.
“This completely new yacht pays homage to classic Grand Banks styling, with a special focus on performance and fuel consumption, wide-open entertaining areas, and supremely comfortable furnishings,” Wong added.
The next Grand Banks Motor Yacht, GB60-04 will also be powered by a pair of Cat C12.9 engines with commissioning seal trial to take place in the first quarter of 2018.
