2013 Columbus Yachts Sport Hybrid 5 cabins + 5 crews
Launched in 2013 by Columbus, Leudin I (Ex Eleonora III) is the first of the Sport Hybrid 40 m award-winning series. The naval architecture and exterior design of this all-aluminum semi-displacement super-yacht are by Hydro Tec in partnership with Columbus. Powered by an advanced hybrid propulsion for greater performance and lower environmental impact, she reaches a maximum speed of 22 kt, a range of 2,500nm at 15 kt and is RINA classed, LY2 and Green Plus (Y) compliant. Her interiors by Hot Lab are characterized by large windows to maximize natural light and eco-friendly materials, while her generously sized deck space provides several sunning and dining solutions made more enjoyable by the highly reduced roll motion effect of the ultra-modern fins zero-speed stabilizer system.
The aim of the Sport Hybrid line is to provide owners with fast sporting yachts without forgoing the comfort, elegance and style of mega yachts. The sleek aggressive lines are designed to merge seamlessly with the environment and enhance the pleasure of luxury yachting in harmony with the sea. Sport indicates the high performances of this Superyacht, equipped with two diesel engines which will give a top speed of 20 knots, with the ability to cruise at 15 knots. The Sport Hybrid line is environmentally friendly and technologically advanced, providing a unique setting for owners who wish to enjoy the sea while preserving the environment. The hull has been designed using CDF analysis and tank tests, in order to optimize the fuel consumption at low and medium speed without sacrificing performances at higher speeds. 40S Hybrid is powered with advanced hybrid propulsion, combining high performance, on a top speed of 20 knots with reduced environmental impact. The choice of using a hybrid system was the result of a deep study done from Palumbo shipyard together with RINA classification society, which let the Columbus Sport hybrid 40m be the first yacht with the hybrid propulsion as an additional notation class issued by RINA; EFP Hybrid Propulsion (Y), Aut CCS (Y), Green Plus (Y) Platinum. The hybrid concept is a main improvement that, thanks to two electrical motors fitted n the gearboxes, allows the 40S hybrid to cruise at 8 knots using only the gensets and the electrical motors. Electrical propulsion system Eco Prop Hybrid will allow navigating at low speed with very limited consumption, high comfort and almost no noise. On board you will be able to experience the thrill of performance and maximum comfort, typical of hybrid yachts. The same hybrid power train can be used as shaft generator using the excess power not used for diesel engines. The hybrid system will allow the yacht to cruise in extremely quiet and vibration free conditions. When cruising with the main engine, the two electrical motors will work as shaft generators allowing nonstop auxiliary generators during long transit.

Both generators are 24 VDC electric start. Generator control is via the main switchboard and alarm monitoring connections are provided. The generator fuel supplies are from the day tanks via duplex Racor fuel filters with unused fuel being sent back to the day tanks. The generators are provided with cooling sea water from their individual sea water intakes with strainers and isolation valves. There are three (3) diesel generator sets as described under the heading of ''GENERATORS''. These are star wound to produce 400V 50Hz 3Ph with no neutral. Each of the generators are connected to the MSB using motorized breakers. All generators an be run by individually or in parallel mode.
Ecoprop Motor / Generators:
The two (2) motor / generators are connected to the main engine reverse / reduction gear via a hydrauliclly operated Steibel clutch and a flexible Vulkan coupling. The motor / generator power has been limited to 75kW. With the main engines running between 1100 - 1800 RPM, one of the motor / generators will feed the main switchboard and power to the yacht via one of the water cooled frequency drives. The motor / generators are not arranged for parallel operation. With the main engines off and all three (3) generators running in parallel, both motor / generators are supplied power from the main switchboard via another water cooled frequency drive to drive the main propulsion shafts.
Fresh Water System:
Grey-Black Water/Waste System:
There are two (2) tanks - one black and one gray. Both have Jotun coating system.
Lube Oil System:

Compressed Air System:
There is supplied an air condition and ventilation system on board designed by Condaria. The central chiller unit provides chilled water at approx. 6 degrees C to fan coil units located throughout the vessel and to several fresh air make up units. Mechanical ventilation is provided by the aforementioned fresh air handlers and by exhaust fans. There is also a separate mini chiller to provide cooling to the shore converter and electrical propulsion system.
The main chiller plant is a reverse cycle type which supplies water during the summer at 6 degrees C and in the winter at 37 degrees C. The refrigerant is condensed using a fresh water closed loop which in turns is cooled by a separate salt water circuit and a plate type heat exchanger. The chiller plant consists of:
Chilled Water Pumps:
Cooling Water Pumps:
The cooling water pumps are hard mounted on the aft section of the chiller skid. They are fitted with isolation ball valves with one pump in operation and the other in standby. They supply fresh cooling water to the chiller plant condensers which then flows through a sea water cooled heat exchanger.

How Hybrid Works
Columbus yachts Hybrid Propulsion System combines several elements known for their reliability into a single whole, creating a revolutionary flexible system while maintaining a very friendly user interface. Benefits related to a Hybrid Propulsion System are to be considered as the sum of the specific benefits relate dot each “MODE”. Using a conventional Propulsion System (engine, gearbox, shaft, propeller), changes were made to the gearbox. A PTI/PTO (Power Take In / Power Take Out) was installed to the gearbox, the same kind of PTO used for hydraulic stabilizers before the advent of separate hydraulic power packs, along with an electric motor and a hydraulic clutch. On the Columbus 40M Sport Hybrid, the electric motor is considered another service element, together with the bow thruster, the galley, and so on. The motor is connected to the primary electric panel and powered by two generators. Using the PTI/PTO, the electric motor has three electric operational modes, easily controlled by pressing a button on the touch screen.
Electric Operational Mode
This technology, which is several decades old, is often applied on ferries and cruise ships, and is known as diesel electric propulsion. The generators are running and provide electric power to the electric panel which then regulate the electric motor as a service element. Each electric motor on the Columbus 40M Sport Hybrid absorbs 75 kw out of the available 200 kw, 100 kw per generator, for a total of 150 kw. 50 kw are therefore free for other uses. The clutch is engaged, the electric motor turns the gearbox which in turn revolves the propeller.
Benefits related to the “Electric Operational Mode”
When in “Electric Mode”, the yacht behaves like a sailboat: zero noise, exhaust and vibration, while her speed is relatively slow. Each motor’s upper limit of 75 kw gives the yacht a top speed of 8 knots, but in complete silence. Another plus related to the Electric Mode is the fuel consumption reduction: approximately 80 liters/hour. A remarkable advantage for a 40M yacht.
