ISA Yachts has launched the first ISA 140, christened Silver Wind. The 43.6m (143ft) yacht, which hit the water on schedule, is a three deck planing composite motoryacht powered by a unique hybrid propulsion system.

The yacht’s exterior lines are the work of Andrea Vallicelli and are charsilverwindacterised by strong diagonal lines run that from the sundeck to the stern.

Interior design will be contributed by Nuvolari & Lenard. Ten guests can be accomodated in five cabins. Silver Wind features extensive outdoor spaces, a large sundeck and a beach area with a generous swimming platform. Comfort at anchor is guaranteed by fixed fin stabilisers with electric actuators.

The hybrid propulsion system was developed by Siemens and ISA Yachts, and can run at a maximum speed of 32 knots and a cruising speed of 26 knots. The advantages of the hybrid propulsion system are numerous: the main engines and generators run less and require less maintenance; the main and auxiliary diesel engines can always operate at peak efficiency, thus reducing the specific fuel consumption and gas emission; there are lower noise levels and if the generators set fails, two shaft generators will operate the electric users; if the main engines fail, the two generators can power the propellers.

The ISA 140 series is the company’s largest semi-custom superyachts 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 largest ever made on a single mould and in 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.

Silver Wind is scheduled for delivery in July 2014.
