First big manufacturer to go with Cummins' pods
Grand Banks have announced an interesting addition to their trawler-style Heritage Series.
The 41 Heritage EU, to be launched next summer, will be fitted with the Zeus Propulsion System from Cummins MerCruiser Diesel.
Zeus utilises twin pods mounted in tunnels in the hull that use independent vectoring for dramatically improved high-speed handling and easier berthing.
Whereas Volvo’s IPS units have forwards-facing propellers, these face backwards like a traditional marine prop.
Cruising speeds for the 41 Heritage EU with twin Cummins QSB5.9 diesels are estimated at 14 to 16 knots, with estimated top speeds of 22 to 24 knots based on engine size.

The Zeus pod system is also said to improve fuel efficiency by as much as 30%, and create more living space, with the pods requiring less space devoted to the engine room than traditional shaft drive systems.
Zeus also uses a joystick control system with a station-keeping feature that uses GPS technology to keep the 41EU in place.
It is also said to be able to maintain a fixed heading within a tight area, even in strong currents.
The 41 Heritage EU will be the first boat of her kind to utilise the new Zeus system.
The 41 will also please punters waiting for a Grand Banks of that size since the popular 42 Heritage was withdrawn in 2005.
