Validation of HamiltonJet EHX – a high-speed hybrid water-jet propulsion system

HamiltonJet has developed a fully integrated hybrid propulsion system called EHX, which complements the company’s waterjet and controls products. To gain experience and validate the performance of the system, HamiltonJet decided to convert its own test boat, a 15m foiling catamaran named Aria, to full EHX hybrid drive. The results were demonstrated at this year’s Americas Cup in Auckland, where the boat made its debut hosting guests and customers. This presentation looks into the findings of this work and how a fully integrated solution offers the best result for boat builders, architects and owners/operators.
