The archived report describes a 5.2 m (17 ft) aluminium centre-console RIB powered by the IE 50 electric outboard and a LiFePO₄ battery pack. During sea trials, the boat reached a reported maximum speed of 29 knots.
The boat and system
The source identifies the vessel as the Porrima P111, an aluminium RIB with an estimated dry weight of approximately 695 kg / 1,533 lb. It lists the propulsion as 50 HP continuous output, with 75 HP peak output.
Why the result matters
The original report describes smooth operation with no tailpipe emissions during the trial. Its key figures and test conditions should be checked against the original trial record before re-publication.
“29 knots. Zero emissions. Proven performance.”
