HX Expeditions Launches Electric “Silent Science Boats” for Quieter Polar Research

HX Expeditions, a pioneering name in expedition cruising, has introduced two new fully electric “silent science boats” to its fleet — a move that significantly reduces underwater noise pollution during polar explorations. These MK 5 vessels, equipped with RAD Propulsion’s RAD 40 drive system, will operate from HX’s MS Fram and MS Fridtjof Nansen in both the Arctic and Antarctic.

The new boats are intended for scientific teams, guest researchers, and expedition guests. Their electric propulsion design allows for much quieter navigation, which is vital in sensitive polar ecosystems. Dr. Verena Meraldi, Chief Scientist at HX, emphasized that “sound pollution is one of the most underestimated environmental impacts” in these regions. For marine animals — particularly whales — noise levels can greatly affect behavior and well-being.

Marine scientist Dr. Ari Friedlaender added that the silence of these electric zodiacs enables more natural, undisturbed observations: “We can approach wildlife with far less disturbance, making our observations more natural. It’s a game-changer.”

Safety and environmental responsibility are built into the design: the boats comply with IAATO (International Association of Antarctica Tour Operators) regulations. HX’s long-term plan is to gradually replace all its traditional combustion-engine zodiacs with electric alternatives across the fleet.

RAD Propulsion’s contribution, via its RAD 40 power consoles, underpins this transition to cleaner, low-noise marine propulsion. According to Sam Pickering, Head of Products at RAD Propulsion, the new system “reflects our commitment to developing advanced marine solutions that reduce environmental impact while delivering high performance.”
