Dynamic Stability Systems update

25ft sportsboat launched with Hugh Welbourn's unique patented lateral foil system
10 months have passed since we reported on the Hugh Welbourn conceived Dynamic Stability System (DSS) – the revolutionary new foil package, that cleverly and simply comprises an athwartships foil that extends to leeward, passing laterally through the hull of a yacht, thereby creating lift, allowing bulb size to be reduced, reducing pitching and dramatically increasing performance. (Read part one and part two of the articles about this). Following on from the 27ft test boat we sailed in Spain last spring, so now finally a bespoke, fully tricked-up 25ft sportsboat has been launched in Brisbane using the DSS. The 25 has been very much born of Neil Pryde’s HiFi team in Hong Kong. Paul Murphy, a pilot based there, regularly sails on HiFi (which has a Hugh Welbourn hull on it) and the 25 was built in Australia by HiFi’s Boat Captain/Project Manager, Kevin Costin. Previously Costin project managed the built of another Welbourn design – Bill Wild’s 12.8m Wedgetail. “Paul wanted something that was the fastest possible sportsboat and its run along from there,” states Welbourn of the general concept. The boat has a distinct skiff-on-steroids look to it, with racks and a retractible bowsprit, but with Welbourn’s typical chined hull – something we have seen as far back as his supermaxi Bols – and of course with the DSS lateral foil. The boat is a full carbon construction and its weight is just 400kg – to put this into perspective it is half that of a Melges 24. “The first feedback on the 25 is that it has extreme performance, but it is actually straightforward to sail - it is very stable [something that the 27 test boat wasn’t] and when you are sailing with the foil out you have something under you that it feels like a bigger boat,” continues Welbourn.
