ISA – International Shipyards Ancona is thrilled to announce that it has sold its first ever 43,63-metre composite motor yacht ISA 140’. The all-new ISA 140′ yacht is the only luxury vessel mixing up very high performance with low consumption, thus solving plenty of clients’ dilemma. The announcement confirms the positive sale trend of this well known Italian builder.

One of the many aspects which make the composite motor yacht ISA 140′ special and unique is her propulsion system. Together with a “traditional” propulsion system consisting of two marine diesel engines driving two Rolls-Royce Kamewa waterjets through reduction gear-boxes, which allow the yacht to run at the maximum speed of 32 knots and a cruising speed of 26 knots, the new ISA140 is equipped with a hybrid propulsion system supplied by Siemens, leader in manufacturing hybrid systems, which allows the following operational modes:
• Navigation at high speed with two main engines ON; the electric power for the ship users is generated by the two shaft generator on gearbox. In this mode, the two diesel generators are OFF.
• Navigation 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. 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.

The advantages of hybrid propulsion are countless. The large flexibility of operation modes in the first place. Then, depending on the operation mode of the vessel, the main engines and generators run less hours per years and, when in operation, at higher loads. Both lead to less required maintenance cost.
What is more, the main and auxiliary diesel engines can always operate at its peak efficiency, thus reducing the specific fuel consumption and gas emission. This shall also result in a drastically lower noise level in overall yacht ambient. It is expected that at 8 knots people on board should have a feeling as to stay on a sailing yacht. Last but not least, there is a drastically improvement of the redundancy. 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.
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 and pioneering I-Bridge, second to no other in terms of customisation and integration, always in full compliance with safety regulation.

The ISA 140 yacht series produces 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 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.
Exterior design is the work of Andrea Vallicelli which carries a bold and dramatic feel from the exterior through into the interior spaces. Strong diagonal lines run from the sundeck to the stern, mirroring the flair of the distinctive sweeping staircases. With her 5 cabins, superyacht ISA 140 can accommodate 10 guests, who can enjoy navigation and at-anchor relaxing moments on the yacht extensive outdoor spaces, a huge sundeck and a cosy beach area with a generous swimming platform. Comfort at anchor is guaranteed by fixed fin stabilizers with electric actuators. Interior design will be signed by the renowned Nuvolari & Lenard Design.
All these special features will contribute to the creation of the unique motor yacht ISA 140, whose delivery is scheduled for Summer 2014.
