[dropcap]T[/dropcap]he Genoa-based shipyard has announced the succesfull launch of its new 50m S501 Hybrid today. Following final fit out and dock trials, the yacht will undergo intensive sea trials prior to delivery to her European owner, in time for the summer season and for the official world debut at the next Monaco Yacht Show in September.
Based on a similar design to Vertige, the first in Tankoa’s 50-metre series, S501 Hybrid differs from her predecessor under five key aspects: it is powered with hybrid propulsion package, is a 5-cabin with a main deck owner’s suite and four guest cabins on the lower deck, the galley is on the main deck, instead of lower deck, and it features a touch-and-go helipad.
The project has been developed together with the owner. The interior design is by Francesco Paszkowski Design in collaboration with Magherita Casprini and combines light and modern tones with an abundance of natural materials.
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 offers considerable fuel savings and reduced noise levels. In Hybrid Mode, one of the two main engines shaft 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 shuted 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.
