Switching to a permanent power solution for superyachts Finland’s Yaskawa Environmental Energy / The Switch has developed a permanent magnet propulsion system for superyachts that can push the frontiers of clean energy performance and open the door to Arctic exploration in comfort and with confidence. The Poseidon Power range cuts emissions and includes the three-pronged trident of greater efficiency, increased reliability and superior flexibility over conventional propulsion systems. It offers superyacht builders the option to use diesel electric, hybrid or fully electric power propulsion, enabling low to zero emissions in an age when black smoke from exhausts is an embarrassment.
