The ENDURANCE 50m is the sister vessel to ENDEAVOUR II, a tri-deck explorer super yacht currently under construction at Rossinavi in Viareggio and ordered by an experienced yachtsman.
Following more than two decades of yacht ownership, the vision of this extraordinary yacht was born through the desire to explore the far away and lesser known coasts and oceans of this world, without making any sacrifices to the high standards of comfort that are normally associated with a 50m superyacht. Over six years the concept was developed, at the beginning mainly between the Owner and his advisor Don Dennison, and later with invaluable input from Rossinavi, Enrico Gobbi and Arrabito Naval Architects.
The goal was to have an oceanic yacht for all-year round cruising and a very modern looking vessel that recalls the purity of minimalist style. The result is an expedition yacht with a good volume, visually characterized by many stylish details and appealing design elements.
The yacht’s profile shows a generous use of window surfaces, guaranteeing harmony between interior and exterior areas and ensuring magnificent floor-to-ceiling panoramic views from the interior. The external decks of the Endurance 50 have plenty of space for enjoying the outside, thanks to the various possible configurations of seating, lounging, dining and sun bathing areas. The yacht’s stern features a gym area with impressive ocean view. Last but not least the owner’s suite forward of the main deck benefits from a private opening terrace.
The unique combination of beige and white colours is a distinguishing mark of the yacht and highlights the sleekness of her exterior profile.
The design of the vessel includes all the normally accepted advantages of an explorer vessel such as very long range, economical fuel consumption, main equipment redundancy, main equipment ruggedness, worldwide serviceability of all main equipment, high HVAC (air ventilation, cooling and heating) specification, very powerful and accurate manoeuvrability including dynamic positioning, very high anchoring and mooring capabilities, flexible port and shore access methods, lower daily maintenance requirements and ample storage.
At the same time, the design was developed to provide arrangements and systems guaranteeing maximum comfort during operation, by way of high quality galley and pantry provisions, easy service flow, very low noise levels, efficient stabilization, automatic interior and exterior doors, state-of-the-art entertainment and communication systems, expansive exterior awnings, and, finally a higher top speed than normally expected on an explorer vessel.
Some attributes in more detail:
The yacht is fitted with an innovative diesel electric system that allows for economical cruising at 12/13 knots by using only one 950 kW Caterpillar generator. At 12 knots, fuel range is 6000 Nautical miles, including power to all on-board services when underway. Power is transmitted to two 3600 continuous rotation Rolls Royce azipods, each equipped with highly efficient counter-rotating propellers. A second generator is also fitted for full redundancy. By using both generators on a rotating basis, the oil change interval of these engines is effectively 1,000 hours or 12,000 nautical miles. Should the owner wish to increase speed for any reason, say to avoid approaching bad weather, both engines can be operated to attain 16/18 knots (depending upon fuel load).
The choice of Caterpillar and Rolls Royce was made due to their world-wide serviceability and the ruggedness of the equipment. Both systems are over-specified so that neither are ever pushed to their top limits. The choice of a diesel electric system and fully azimuthing thrusters are essential to attain exceptional low noise (low 30 ’s dba) and vibration levels (no drive shafts), to achieve the very high manoeuvrability required for exploring reefs, turbulent river deltas, and to be able to fully use the dynamic positioning system. Dynamic positioning is very important for an explorer yacht in that it can “hover” for many hours over a protected area, for example coral reefs, without needing to use its anchors. It is also very useful for waiting in a port and on ENDURANCE 50 the captain can manoeuvre the vessel with the single joystick of the system into her berth easily overcoming any winds or currents present, also with the assistance of a 165 kW counter-rotating bow thruster.
The 2 main generators are extremely silent, due to no shaft arrangement being required plus being installed on custom-designed, massive double-mounted flexible foundations specified by van Cappellen, who have defined extremely stringent noise and vibration standards for every area of the yacht. Three other Caterpillar generators of 80 kW each provide electric power when at anchor. They are also double-mounted and operate via a sophisticated power management system that can manage electric power production by way of a load acceptance and shedding protocol. The loading of the generators is therefore always optimal. One the three identical generators is in a separate space and also serves as the emergency generator.
When exploring, the anchoring capability of a yacht is very important. The design therefore includes 3 identical anchors and 3 windlasses. Chain specification is heavier and longer than required by Classification. The third anchor is used principally for stern attachment which is very helpful when mooring in small bays or rivers. For a serious explorer yacht a third anchor is essential as replacement if one of the bow anchors is lost, and as a back-up kedge when preparing for an approaching hurricane or typhoon.
The lighting plan for the exterior of the ENDURANCE 50 has been developed with the intent to create sensational night sceneries that make the yacht recognizable at first sight. Modern led strips and indirect lights have been used overall in substitution to traditional spotlights, for a very fascinating final effect. An elegant indirect lighting system also highlights the grids of thin metal plates, which are a design element positioned aft, and forward, of the main and upper decks superstructure, amidships and on the aft side of the mast.
As far as concerns the naval architecture of the Endurance 50 construction is completely of aluminium and the hull is full displacement. Aluminium has been chosen in order to obtain best consumption performances and highest cruising speed with a low power installed. The hull lines are by Arrabito Naval Architects and have been successfully tank tested. Each single exterior detail of this yacht has been carefully studied by the designers and the outstanding quality of production by Rossinavi can be witnessed at any time by visiting the sister ship ENDEAVOUR 2, currently under construction and scheduled for a 2017 delivery.
