Perini Navi - . Helios, the result of a collaboration between Perini Navis naval architects and Ron Holland, is the second steel-hulled 45-Metre yacht to be launched by this Italian shipyard. The third yacht in this class will be delivered to her owners in Spring 2009. The extra displacement and, hence, increased wetted surface area of the steel hull was ingeniously absorbed into the design to ensure that added drag was kept to an absolute minimum.
