New Zealand-based vessel developer Vessev has introduced a new electric podded propulsion system, the VS–Drive, designed to improve efficiency, durability and cooling performance in commercial and recreational marine applications.
The submersible motor system integrates direct-drive brushless motors with a closed-loop liquid cooling circuit that maintains operating temperatures below 50°C, the company says. The design eliminates gearboxes and long driveshafts, reducing mechanical losses and maintenance requirements.
The VS–Drive delivers a continuous output of 65kW (90hp) at 25kts, with peak output reaching 110kW (150hp). Torque is rated at 400Nm. The motor operates with minimal noise and vibration, while onboard sensors monitor bearing and system performance in real time. The unit’s modular architecture enables straightforward disassembly and servicing.
A vectorable rudder mount enables enhanced maneuverability at low speeds and the drive integrates with Vessev’s retractable hydrofoiling system, supporting operation in varying depths and marina configurations.
The propulsion unit currently powers the company’s VS–9, a 9m battery-electric hydrofoiling catamaran with a cruise speed of 25kts and a range of up to 50 nautical miles. Vessev plans to scale the same drive architecture for larger 12m and 18m vessels, as well as a forthcoming recreational model.
Co-founder and CTO Max Olson said VS–Drive’s internal closed-loop cooling system was among its most useful features.
“The VS–Drive began as a clean-sheet design to overcome one of the trickiest challenges in electric marine propulsion: overheating,” he said. “The result is sustained high-torque output and unparalleled performance in tropical climates.”
The project received co-funding from New Zealand’s Low Emission Transport Fund, administered by the Energy Efficiency and Conservation Authority (EECA).
