ACEL Power’s 50 HP Electric Outboard Propels Porrima P111 RIB to 29 knots in Successful Sea Trial

ACEL Power Inc. today 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.

The 5.2 m (17 ft) aluminum center-console RIB, developed as a tender for the Porrima P111 catamaran, is powered by ACEL’s IE 50™—a 50 HP electric outboard. During recent sea trials, the vessel reached a top speed of 29 knots while delivering a smooth, silent ride with zero emissions. The successful test confirms the system’s capability for high-performance, sustainable marine mobility across a range of vessel types.

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.
