With her five cabins, Silver Wind can accommodate 10 guests. Thanks her unique hybrid propulsion system developed by Siemens and ISA Yachts, Silver Wind can both run at the maximum speed of 32 knots and a cruising speed of 26 knots with a traditional propulsion system consisting of two marine diesel engines driving two Rolls-Royce Kamewa waterjets through reduction gear-boxes, and navigate at low speed of 8 knots with two main engines off; the two waterjets are powered by the two electric motors connected to the gearbox. The two diesel generators also supply power to the electric users. In electric mode, the total fuel consumption is 90 l/h for a range of 2600 nm, so extremely important for yacht transfer without guests onboard, as consumption goes from 55 l/nm at max yacht speed to 11 l/nm with electric mode on.
A further exceptional element is her fully custom-made bridge. ISA in-house electronic department coordinates a panel of important names in the field of electronic navigation systems, such as Transas, which made the bridge concept, Team Italia, which designed the bridge console and Rolls-Royce, which provides the custom-made waterjets control system. The result is a highly technological pioneering bridge, second to no other in terms of customisation and integration, always in full compliance with safety regulation.
The ISA 140 series produces the company’s largest semi-custom model of composite construction with hull and superstructure built from Fibre Reinforced Plastic (FRP). The composite parts of ISA 140, such as the hull, the deck, the superstructure and the accessories, have been built with vacuum assisted resin infusion (VARTM). In particular, the hull is one of the biggest one ever made on a single mould and at one go. The result is a product with superior features in terms of lightness and stiffness, compared to the boats of the same category made with traditional techniques.
