Austrian shipyard SILENT-YACHTS started construction of the first three 24-foot catamarans SILENT 79 ocean class solar based in Italian Marotta. The design of the project concept, the founder and CEO of SILENT-YACHTS Michael Kohler (Michael Köhler) was engaged in Marco Casali (Marco Casali) from Too Design, naval architecture developed Castillo Enrique (Enrique Castilla) from Insenaval. SILENT 79 will be the flagship of the shipyard.
SILENT 79 can be called a new stage in the evolution of past models of the company. In particular, the design of the catamaran, much refers to his older, but much smaller in size brother SILENT 55.
“For the solar panels need a large surface. We had a task to free up that much space as possible, but to keep harmony in the silhouette of a catamaran. I think we succeeded. I tried to create an interesting Italian design: refined and noble. This boat looks good, and at the same time it is practical,” says Marco Casali.
Catamaran hull will be cast and built by the method of vacuum infusion. This will facilitate a sandwich of fiberglass and improve its acoustic and insulating qualities.
The exterior design SILENT 79 emphasis on straight lines and large Windows. On the one hand, the glazing allows you to enjoy the salon panoramic sea views, on the other — will reduce the need for additional artificial lighting. Cockpit on main deck aft in addition to the standard rest area will be located bar. But under a beach club reserved the bow of the main deck.
The layout of the cabins on each catamaran will be different from one another: the desire of their owners. In the standard layout width will be nearly 11 meters. Inside will house the galley, sitting area and dining area. On the lower deck is expected from four to six guest cabins and two crew cabins for two or three people each. But on the first of the boats under construction the layout is changed so that the two cabins in the aft of the ship is the apartment owner with a spacious living room, study room and sauna.
Finish all the rooms of the “green” catamaran is, of course, made from materials that are recyclable. The authors of the project promise is minimalist, ergonomic and at the same time a luxurious interior design.
Solar panels will occupy the roof above the salon and the cockpit. In addition, they will be located on the open roof of the bridge is shaped like the spoiler of a sports car. Only SILENT 79 will be installed 70 high-performance panels that can create voltages up to 25 kV, with the most advanced charge controllers of type MPPT (“maximum power point tracking”, “tracking maximum charge level”). Lithium batteries, similar to batteries used by Tesla will not stop at night. The inverter voltage 15 kVA would supply electricity for the domestic needs of the crew and boat.
The ship provided a generator, but it is expected that its use will be required only in extreme cases, to recharge the batteries when long time, it is necessary to go at high speed, or a few days were cloudy. For cooking or the operation of the air conditioner while parked on 79 SILENT generator is not needed.
In absolute silence, completely without the use of additional fuel, the catamaran at speeds of 6-7 knots can take up to 100 nautical miles a day. The maximum speed that it will be able to develop, will be 20 knots.
To move the ship will be a pair of electric motors of 50 kW each, in the standard “cruising” modification or 250 kV each in option E-Power. In addition to the quietness and lack of emissions they are also distinguished by a low vibration level. However, at the request of the owners of SILENT 79 may be a hybrid with two diesel engines 220 HP
In a non-hybrid embodiment, the grid 79 will be SILENT easy and does not require maintenance, allowing to use the catamaran in the mode of Autonomous navigation. This will significantly reduce its cost compared to diesel counterparts. Base price SILENT 79 is 3.4 million euros.
As the catamaran does not need the engine room, it boasts the most a large tender garage in her class. Plenty of room for boats with a length of 4.5 meters, amphibious vehicles and a gyrocopter on floats.
Two of the three catamarans under construction have already found their owners. The first launching of the SILENT 79 scheduled for 2020.
