  "account": "Incat's latest catamaran, boasting a 40 MWh battery system, has captured global attention as the largest purely electric ferry to date. This innovative design adheres to updated DNV class rules, striking a balance between safety and innovation. As ferry operators worldwide increasingly embrace alternative propulsion methods to lower emissions and noise, the trend toward sustainable tourism further fuels this shift. Light, battery-electric multihull vessels, known for their low water resistance and high energy efficiency, are rapidly gaining popularity. Their low water resistance, coupled with high energy efficiency, promises significant reductions in operating costs. The growing availability of charging infrastructure is making electric ferry operation increasingly viable. Multihulls offer enhanced maneuverability, spacious decks, and higher speeds suitable for frequent daily runs. Their inherent stability also enhances passenger comfort, even in rough seas. The business case for lightweight battery-electric ferries gains momentum as DNV's ship register shows a surge in electric propulsion vessels. As of the end of 2025, 433 battery-powered vessels are actively registered with DNV, and another 271 are under construction. For high-speed crafts, the market is shifting from speed to efficiency, aligning with lightweight aluminium construction's strengths. Larger aluminium vessels are becoming more economical, with reduced weight leading to lower energy demands and shorter charging times. The world's largest battery-electric aluminium ferry, China Zorrilla, recently made its debut in August 2026. Built by Incat in Hobart, Tasmania, this 130-meter-long, 30.5-meter-wide vessel can transport up to 2,100 passengers and 226 cars at a speed of 25 knots. The ferry, named after a renowned Uruguayan actress, operates on a 30 nautical mile route between Buenos Aires and Colonia del Sacramento, twice daily. Its battery-powered electric propulsion system and quad waterjets were provided by Wärtsilä, with four 10.290 MWh lithium-ion battery systems manufactured by Corvus Energy. The decision to opt for electric propulsion over LNG was driven by the desire for zero emissions and minimal noise and vibration. However, this transition presents a trade-off: a limited operating range, making battery capacity a crucial design consideration. Incat and DNV have collaborated closely on this novel design, adapting safety requirements to accommodate the unique characteristics of the large battery system. Comprehensive risk assessments were conducted to address internal fire risks and ensure the vessel's safe operation.",
  "summary": "With a 40 MWh battery system on board, Incat’s latest catamaran newbuild has made headlines as the largest purely electric ferry to date and likely pioneer of a new vessel class. The vessel’s design was optimized in line with DNV’s updated class rules, ensuring a high level of safety while supporting innovation. Ferry operators around ...",
