Stockholm-based Candela Technology AB, a leading manufacturer of electric hydrofoils, has found its first customer outside Europe for its P-12 hydrofoil ferry: Meridian Energy, a New Zealand energy company on Lake Manapouri. From 2025, the electric hydrofoil ferry will transport workers from the hydroelectric power plant across the lake every day. The 12 metre long and 4.5 metre wide vessel can carry up to 30 passengers.
Unlike their flightless heraldic animal, the kiwi, some New Zealand commuters on Lake Manapouri will soon be able to "fly". Their employer, Meridian Energy, is investing in green energy and helping its employees to enjoy perhaps the most beautiful commute in the world. From next year, they will be able to glide virtually silently across Lake Manapouri, which has just been voted "New Zealand's most beautiful lake", instead of using the old diesel ferry.
Last year, the Candela p-12 started its liner service in the Stockholm archipelago:
80 per cent less energy consumption
The futuristic-looking hydrofoil is intended to replace the current diesel ferry and save around 240 tonnes of CO2 emissions every year - roughly equivalent to the emissions of 52 petrol cars. Computer-controlled hydrofoils lift the hull of the P-12 above the water at high speed and reduce friction. This reduces energy consumption by 80 per cent compared to conventional ships. With a top speed of 30 knots and a range of 50 nautical miles at 25 knots, it is the fastest and most efficient electric ferry in the world. In addition, the impact on the shoreline and thus on many native species is greatly minimised by the low wake.
At its heart, however, is the flight controller, which automatically stabilises the ship during the journey by adjusting the angle of attack of the wings 100 times per second to the wave height and wind speed. This means that even sensitive passengers need not worry about seasickness. Even in rough weather, they feel 90 per cent less g-forces than on a conventional boat.
