An Integrel 48-volt fast charging system can put an impressive 12kW back into the batteries via a pair of alternators when the boat is motoring


proven in other fields. What we are doing is showing that it can be applied on a different, smaller scale and all our work makes us believe firmly that it can be. ‘As we’ve shown with our work with


integrated systems and solar panels we believe that the route forwards is via incremental change. As a result, in this case it may well be that to start with, the main propulsion system remains as a diesel, but the goal with this new technology would be to phase this out eventually. And once we’ve proved the concept, I’m pretty sure that will happen quickly because unlike the high-pressure


hydrogen route, our system will allow us to store hydrogen at much lower pressures which in turn makes the entire system more manageable and scalable. ‘Having said that, because of the weight


‘Our skylights and windows have a built-in solar membrane’


of the system there will likely be some practical restrictions on just how small you can go, but for our range of boats I see few issues here. Overall, the work we’ve done shows that


there is no reason why we shouldn’t be powering the entire boat with this new technology and that is really exciting.’ Meanwhile, and aside from the leading-


edge developments when it comes to power generation, McConaghy’s core


business still revolves around creating high-quality performance boats. ‘Whatever the final choice when it


comes to power, we're still creating an advanced platform for our customers to create a custom-built boat where owners can change the layout, specify individual finishes and create the unique boat that they’re after. We work very, very closely with them on every single detail. ‘Yet among all this choice and the wide


variety of layouts and styles that emerge when boats hit the water, when it comes to the future of power and the need to go green, the overwhelming majority of our clients are on the same page and moving in the same direction.’ www.mcconaghyboats.com
