The world’s first electric hydro-foiling ferry, a 30-seat Swedish-designed Candela P-12, is destined to be launched by Meridian on Lake Manapōuri next year (2025).

It will also be the first one to be seen outside of Europe.

The new ferry will have computer-guided hydrofoils which rise the hull above the water, reducing drag by up to 80% and giving it a cruise speed of 25 knots and wake of less than 15cm.

Meridian’s GM of Generation Tania Palmer said she expects it will save 240 tons of carbon emissions each year – equivalent to taking 52 petrol cars off the road - and was one way the company was reducing its emissions from internal transport, contributing to its goal of halving emissions by 2030. 

“We have to be bold and innovative to reduce emissions. This deal is the result of a global search to identify the latest and best technology for our needs, and one that’s suitable for such an incredible natural environment."

However Palmer was tight-lipped about the new boat's cost.

"At the start of the ferry-purchasing process Meridian sought Expressions of Interest and then worked through potential solutions with several boat builders, including some in New Zealand."

"Due to the nature of these negotiations, the purchase price of the Candela P-12 remains commercially sensitive," she said.

Palmer said new charging stations would be installed at both Manapouri's Pearl Harbour and West Arm power station.

"We are currently investigating the size of chargers, with the maximum size being 175 kW."

"The charging time will be approximately 40 minutes, although the boat can do the return journey without charging," Palmer said.

Palmer said the Candela had a battery that is was expected to last approximately 5 years.

The new ferry will replace the existing 42-seat diesel powered catamaran which has provided daily transport for Meridian staff and contractors servicing the Manapōuri hydro power station since 2009.

"One we’ve completed a bedding-in period with the Candela, the old ferry will be sold," Palmer said.
