Test drive results
After some time admiring the interior and exterior qualities of this world-class sport yacht, it was time to take her for a test. Once behind the wheel, we easily accelerated from a standing start to near 30 knots in a few seconds. The hull lift was even and effortless. The triple IPS 600s deliver an impressive ride. Even at top speed of just under 30 knots pushing an incoming tide, there is minimal engine noise on this yacht. Additionally, the triple IPS installation allows the hull to lift uniformly onto the plane at a touch over 13 knots. Behind the wheel, the 5800 is a dream to drive – powerful, easy to handle with positive steering, excellent vision and of course, manoeuvrability.
While the 5800 is a big volume sport yacht with impressive modern lines and aerodynamic styling, fuel consumption is low. At 29 knots, each of the IPS 600s consumed 82 litres per hour with the yacht’s fuel and water tanks fully loaded. At a comfortable cruising speed of 20.5 knots, fuel consumption dropped to almost half – some 42 litres per hour. The triple IPS 600 engines have been installed in a staggered formation, with the centre engine set slightly forward of the port and starboard motors. This was necessary because the garage is located immediately above the engine room and diminished head height necessitated an innovative approach. A shaft extension was used to ensure that all three IPS drives were in line. Entry to the engine room is from the crew quarters through a cockpit hatch.
Nothing has been spared in affording the skipper and navigator complete comfort. Twin ergonomically designed bolster chairs with high backs provide seating at the helm. Forward vision is excellent, with only a slim line support between the two large forward screens. The screens are equipped with fresh water heavy duty, variable speed wipers and demisters have also been installed. There is also a night-running mode with overhead red lamps.
On the multi-level dash, twin Raymarine E120 GPS screens with integrated camera displays from the swim platform, engine room and anchor, provide a wealth of information. The 5800 sport yacht is equipped with Volvo’s EVC and a single multi-function screen gives realtime readouts on the performance of the triple IPS 600s. The IPS joystick is positioned just forward of the adjustable wheel, while the electronic controls which synchronise with the triple drives, are positioned on the skipper’s starboard hand.
Accommodating down below
The accommodation deck has four cabins and three bathrooms. The overall layout is well defined and has allowed different cabin configurations which affords accommodation for seven in complete comfort. Most impressive is the full beam master which is positioned almost amidships. Entry is aft of the stairwell and the ensuite is positioned to port. The ensuite is by no means deficient in space or fitout. It features a timber floor, separate shower and toilet, wall mounted mirror and stylish vanity basin.
The large portrait oval portholes on either side of the master cabin make an immediate impression and importantly, each of the centre portholes can be opened. There is a chest of drawers on the portside of the cabin while set opposite is a comfortable two seater lounge. On the forward bulkhead, there is a large Sony flatscreen plasma and adjacent is a desk with jewellery compartment, large mirror and a padded ottoman.
Overhead Bose speakers provide a surround sound effect for the cabin’s entertainment system. The cabin is beautifully appointed and lacks nothing in terms of facilities and privacy and positioned amidships, will afford a restful night’s sleep. There is a second double located in the bow of the sport yacht. Featuring an island double, the cabin offers plenty of space and storage. Two portholes and an overhead hatch provide plenty of natural light and ventilation. The cabin has its own entertainment system, twin hanging lockers and an ensuite with separate shower stall. The remaining cabins were not added as after-thoughts – each has its own entertainment system and climate control. In addition, the starboard twin has a separate entry to the master bathroom positioned between the twin cabin and the forward cabin.
The 5800 Sport Yacht offers so much in refinements, space and innovation.
While Riviera build bigger vessels and their flagship 70 launched last year, this sport yacht will have enormous appeal as it offers so much in terms of usage. It has the power, the performance and the pedigree to become Riviera’s finest.
