Kiwi Diesel Electric Hybrid at Hutchwilco NZ Boat Show

by admin

The first Diesel Electric Hybrid boat to be entirely designed and built in New Zealand will make its first public appearance at the Hutchwilco New Zealand Boat Show in Auckland in May.

The new Herley Boats 3400 Powercat Diesel/Electric Hybrid is a 10.4m LOA displacement catamaran. It features twin 60kw/100kw peak electric motors and 300Nm of torque run in parallel from a 120kw diesel generator, coupled to a permanent magnet generator and Lithium-ion battery storage. This will allow the system to re-charge within an hour while at sea.

The Herley 3400 Powercat will have the ability to run on either lithium or diesel or, for top performance, on both systems simultaneously. The vessel’s on-board control system will allow the skipper to choose between an electric-only drive mode for zero fuel burn; economy cruise for the greatest fuel efficiency; or performance mode for high-speed operation.

“We are literally putting the power in the owner’s hand,” says Herley Boats’ Nick Herley. “They can choose to use their efficient diesel inboard motor, cruise silently on their electric motors or pick up the speed in their Hybrid mode.”

The 3400 Powercat will also have an projected cruising range of over 1300 nautical miles on a single 640- litre tank, thanks a hull form that has been specifically designed to create minimal underwater drag.

The 3400 Powercat Diesel/Electric Hybrid will be on display on the Herley Boats stand at the 2020 Hutchwilco New Zealand Boat Show, at the ASB Showgrounds in Greenlane, Auckland on May 14-17. Easy to download, print-at-home tickets to the show are now available on-line at
