Tankoa S501 Hybrid world debut at the 2019 Monaco Yacht Show

Based on a similar design to Vertige, the first in Tankoa's 50-metre series, S501 Hybrid differs from her predecessor in five key aspects:

- Tankoa S501 hull #2 is powered by a hybrid propulsion package.

- She has a 5-cabin layout with a main deck owner’s suite and four guest cabins on the lower deck.

- The owner’s galley is on the main deck. The crew galley is on the lower deck

- Her foredeck features a touch-and-go helipad and storage for 5 e-bikes. Tender and jet-sky are stowed on the deck

- The project has been developed together with the owner.

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 with the main engines off. 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 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 Booster 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 of 18 knots.

THE INTERIORS

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’s lower deckwill be equipped with a gym and beach club, two VIP cabins with king-size beds and two guest cabins with twin berths (one with a Pullman berth), plus crew quarters and service areas.

On main deck, the cockpit comes with an oversized sun bed, U-shaped sofa, coffee tables and bar with fold-down bulwarks for more floor space and better sea views.

The interior offers a spacious saloon, dining room, galley, pantry, dayhead and a superb master suite with office and lounge equipped with a fold-down terrace to starboard and a large openable window to port.

The upper deckhas 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 deckprovides ample spaces and comfort with sofas, sun-beds, chaise longue, up & down tables, bar and a generous Jacuzzi.
