A plug-in hybrid electric fast ferry designed by Incat Crowther is to enter service in Auckland, New Zealand, following successful sea trials. It is the first vessel of its kind in Auckland and will be operated by Fullers360 for Auckland Transport on the Auckland-to-Devonport commuter route.
The 32-metre ferry, which was built by Q-West Boat Builders with systems integrated by Hamilton Jet, features four Danfoss EM-PMI540-T4000 electric motors, Hamilton HTX42 water jets and hybrid electric systems. The liquid cooling system features pumps and heat exchangers for the electric motors, converters, inverters and switchboards, and chillers for the batteries. The vessel is expected to reduce carbon emissions from Auckland Transport’s fleet by 750,000 kilograms per year.
During sea trials, the ferry reached a top speed of 36 knots on all-electric mode, while the electric propulsion and onboard systems “consistently” met and surpassed expectations.
“This new vessel will offer Aucklanders a world-class, low-emission travel experience,” said Dan Mace, Incat Crowther’s technical manager. “Incat Crowther’s expertise in conceptualising the vessel design to ensure it is tailored for Auckland Transport’s operational requirements, combined with the application of the latest digital shipbuilding technology, was critical to the successful delivery of this project. This tailored design approach also ensured the vessel’s electric drive system was accurately and reliably integrated from the outset.
“Embedding digital shipbuilding processes throughout the project will also provide a range of benefits to Auckland Transport and Fullers360 over the long term – including lower maintenance costs and improved operational outcomes through streamlined training for staff.”

The ferry accommodates 299 passengers and 20 bicycles and has been designed to provide passengers with a comfortable and highly reliable service. There is a range of seating options onboard, including tables with USB ports, as well as fold-up luggage compartments and floor-to-ceiling windows.
“Incat Crowther has been great to work with throughout this project, from the inception phase through to rollout,” said Liam Dowling, head of innovations and asset development at Fullers360. “The flexibility, adaptability and spirit of partnership that's gone through this project has been key to making Auckland’s first plug-in electric-hybrid ferry a reality.”
