The launch of the 50m/165′ Tankoa S501 Hybrid took place at the Genoa shipyard. After the final set-up and the tests on the dock, the boat will be tested at sea, before being handed over to the European owner. The debut of the S501 in front of the general public will be at the Monaco Yacht Show 2019 (25-28 September).
The design is similar to that of Vertige, the first yacht in the 50-meter Tankoa series. However, the S501 Hybrid is different in many ways. Primarily, the propulsion, that in this case is hybrid. There are also 5 cabins, with a master suite on the main deck. The position of the galley, which on Vertige was on the lower deck, is also different: on the S501 it is on the main deck. Lastly, the forward area has been equipped with a touch-and-go helipad.
S501 HYBRID SYSTEM
The yacht is powered by twin MTU 8V4000M54 (895 kW) and two 300 kW electric motors fed by two 250 kW variable speed generators.
In DEM mode (Diesel-Electric mode) the electric motors are fed by two variable-speed generators, allowing for speed up to 10.5 knots and a max. range of 4,900nm. This DEM mode permits considerable fuel savings and reduced noise levels.
In Hybrid Mode, one of the two main engines shafts generates the needed electrical power to run the second electric motor for propulsion and hotel needs. At 12 knots, the yacht will have a cruising range of approx. 4,000 nm. In this mode, the two diesel generators are simply shut down during navigation.
In Traditional Mode, the yacht can sail at 16,5 knots using both main diesel engines for propulsion and a diesel generator feeding the hotel loads. In this case, the variable speed generators self-adjust their rotation speed to the required load.
In Full-Speed Mode, with both main engines and generators supplying power to the two electric motors and feeding the hotel loads, the yacht will reach a top speed in excess of 18 knots.
The interior design is by Francesco Paszkowski Design in collaboration with Margherita Casprini and combines light and modern tones with an abundance of natural materials.
S501 Hybrid’s lower deck will be equipped with a gym and beach club, two VIP cabins with king-size beds and two guest cabins with twin berths, plus crew quarters and service areas.
On main deck, the cockpit comes with an oversized sun bed, U-shaped sofa, coffee tables and bar.
The interior offers a spacious saloon, dining room, galley, and superb master suite with office and lounge equipped with fold-down terrace to starboard and a large openable window to port.
The upper deck has been designed around spacious entertainment areas for guest’s relaxation, with a dining table and access to the comfortable sky lounge. The foredeck includes a solarium and open-air lounge, all designed to offer maximum privacy.
The fly deck provides ample spaces and comfort with sofas, sun-beds, up & down tables, bar and a generous Jacuzzi.
