ACEL Power Inc. announced outstanding test results for the new Porrima P111 rigid-inflatable boat (RIB). During sea trials last week, the 5.2 m (17 ft) aluminium centre-console RIB, powered by ACEL’s IE 50™ 50 HP electric outboard and with Lithium Ferro-Phosphate (LiFePO₄) battery pack, achieved a max speed of 29 knots while maintaining smooth, no emissions operations.

Key Performance Highlights

Raising the Bar for High-Performance Electric Propulsion

“These trials prove that clean doesn’t mean slow,” said Anthony Liu, Co-Founder & CEO of ACEL Power. “Pushing an aluminum RIB of this size to 29 knots—without fumes, vibration, or carbon emissions—demonstrates the headroom our high-voltage architecture still has for commercial and recreational duty cycles.”

Why It Matters

• Power-to-weight advantage – The IE 50™ delivers instant torque and high efficiency in a lightweight package, offering performance on par with conventional 70 HP systems while maintaining a lower overall weight when paired with ACEL’s modular battery pack.
• Endurance & safety – The RIB can cruise for roughly two hours at planning speed, with LFP chemistry offering >3,000 charge cycles and superior thermal stability.
• Plug-and-play integration – Features like the digital throttle, floating NFC smart keys, and cloud-based diagnostics are designed for seamless installation and intuitive operation right out of the box.

Next Steps

While the RIB was developed as a tender for the zero-emission Porrima P111 catamaran, its successful performance demonstrates that ACEL Power’s electric propulsion system is well-suited for mission-driven vessels focused on sustainability, such as support craft for clean energy expeditions, scientific monitoring platforms, and next-generation tenders for electric or hybrid motherships. ACEL will exhibit IE-Series at METSTRADE (Amsterdam) this November.
