Danish shipyard X-Yachts has released new details on the 15m (49ft) X4⁹E. An evolution of the shipyard’s X49 model, the ‘E’ yacht will not be powered by traditional diesel engines rather two 10kW electric ones. There will also be a 28.8 kWh lithium battery bank and an onboard DC generator with a capacity of 11 kW with a diesel generator for backup. The shipyard estimates that the range of the X4⁹E would be 22 miles at 5 knots.
”We didn’t want to be first movers in this area but preferred to wait until technology and knowledge had matured properly”, said Kræn Nielsen, CEO of X-Yachts in a statement to the press. ”And I’m really happy to say that the time finally is right to present the first X-Yacht with electric propulsion.” The propulsion system in the new X4⁹E is delivered by Finnish Oceanvolt, a longstanding partner of the shipyard.
The X-Yachts technical team worked closely with the owner of the first X4⁹E to make sure it was ready to hit the water. “The boat has been upgraded in several areas, such as rigging, electronics etc. We have chosen a hybrid system for this boat, which means installing a diesel generator with capacity to take care of power in situations where battery capacity is not sufficient”, explained technical manager John Morsing.

X-Yachts ‘E’ Yacht Model
The former engine compartment of the X4⁹ has become a dedicated technical space for the ‘E’ model. This area of the yacht now houses a battery bank, a charger/inverter, BMS, controllers and more. The shipyard chose to install two electric engines for more power and higher safety.
Built with Rechargeable Batteries
One of the innovative aspects of the X49E is its rechargeable batteries. As the yacht can produce up to 3.5kW while sailing, it can regenerate power and refuel itself. The shipyard explained that sailing for eight hours will charge the batteries from empty to full.
As more yacht owners understand the importance of eco-friendly, sustainable boating practices, vessels like the X4⁹E will undoubtedly grow in popularity. This exciting ‘green’ technology is a hugely positive step for the yacht world.
