XNRG.tech, a subsidiary of Xtenders, has bought its high-performance energyX 6.3 carbon RIB to the world stage at the 2025 Monaco Energy Boat Challenge.
The vessel was powered by Chinese based high-performance electric outboard manufacturer ExploMar’s WAVE 300 electric outboard (300hp), which made its official debut at the event.
The WAVE 300 is a 300hp electric outboard system, powered by a 125kWh high-energy-density lithium-ion battery.
The propulsion system was delivered to XNRG.tech in mid-2024, and has since undergone extensive real-world testing.
At this year’s Monaco Energy Boat Challenge, the system was used to enable the energyX 6.3, powered by the WAVE 300 system, to finish in first place in the Electric propulsion system – Open Sea Class during the MEBC Endurance Race.
We are proud to support XNRG.tech in this challenge and thrilled to see WAVE300 prove itself on such an international stage.

The RIB completed 27 laps on a 0.66-nautical-mile circuit, with a top speed of 42 knots, and returned to the dock with 11% battery remaining.
The energyX 6.3 was also used in the 16 Nautical Mile Speed Trial, racing from Monaco to Ventimiglia.
The craft was the first electric boat to cross the finish line, completing the course in 29 minutes with 40% battery remaining.
“We are proud to support XNRG.tech in this challenge and thrilled to see WAVE300 prove itself on such an international stage,” said Alex Dong, CEO of ExploMar.
“Our on-site engineers worked closely with the XNRG team during every stage of preparation and racing.
Technical support
“Behind the scenes, our R&D team in China provided continuous technical support to ensure optimal system performance.
“Participating in MEBC has given us the opportunity to showcase not just the power and reliability of WAVE300, but also the strength of our engineering team and product development capabilities.”
The 2025 Monaco Energy Boat Challenge is organised by Yacht Club de Monaco, with support from the Prince Albert II of Monaco Foundation, UBS, BMW and SBM Offshore.
The event is designed to imaginine and test the latest evolutions in cleaner propulsion. “Technologies are advancing, the ideas also, now we must speed up.
“We all have a role to play – institutions, manufacturers, owners – it’s time to turn intentions into actions,” said Yacht Club de Monaco general secretary Bernard d’Alessandri.
