With three Volvo Penta IPS 600 pod drives and a whole new level of luxury, the latest Riviera Sport Yacht breaks new ground

  • World-class fit and finish
  • The moulded fiberglass hull, and everything down to small parts and mechanisms are fully computer-designed
  • Spacious outdoor area with built-in unobtrusive amenities
  • The anchor winch and chain is hidden below deck to give a cleaner look
  • Top speed and low noise levels are impressive

The Riviera 5800 Sport Yacht is the biggest model in the SY range and features the revolutionary triple Volvo Penta IPS 600 pod drives with forward-facing propellers – a first for Riviera.

Design

The moulded fibreglass hull has been designed using NX 3D CAD computer modelling and everything down to small parts and mechanisms are fully computer-designed. The joinery throughout is CNC machine cut and coated using our robotic varnish system.

"While we had some basic parameters such as the indoor/outdoor atmosphere, we had the opportunity to break new ground with the overall design. We have gone away from the bowsprit for the first time and hidden the anchor winch and chain below the deck level to give a cleaner look to the forward deck," explains Sport concept design manager, Stephen Ford.

"The (IPS) propulsion system alone had a major effect on the design simply because it allowed us to utilise much more accommodation space. The result is a magnificent four-cabin, three-bathroom layout with a large, open full-beam master stateroom amidships with distinctive portlights in the hull sides that flood this cabin with light."

The 5800 SY is offered with an alternative layout featuring a below-decks galley. Riviera says it opens up the saloon, providing a large additional lounge in the starboard aft quarter of the saloon.

Build quality

The 5800 SY boasts a fully resin-infused hull, while the decks and hardtop are handlaid moulded fibreglass with foam core. There is a watertight collision bulkhead forward, independent compartments throughout the hull, solid GRP keel and chines.

The boat is bundled with the latest edge digital switching, CAN-bus technology that allows you to control the DC circuits from a touch-screen control panel at the helm and the electrical board.

There are preset modes so you can program your 5800 SY in advance for your preferred way of boating. Night mode brings the lights on, party mode adds music DVDs and the Bose, and so on. Full systems monitoring and tank levels are displayed on the 3.5in colour control screens.

Among the other new technologies are interior light dimming, timer controls, automated circuit control, wiper speed control and wash function. Batteries are the no-maintenance AGM types, with 24v house power and a whopping optional 5000W inverter for running the AV systems, icemaker and freshwater pump sans generator. The navigation lights are LED types.

Engineroom access is through a hatch in the teak-topped cockpit that leads into a huge lazarette that, with optional fit-out, can be turned into crew’s quarters with en suite. A waterproof door leads back aft from here to the rear-mounted triple Volvo Penta IPS 600s.

Coupled with a jackshaft, the centre engine is located forward of the outboard engines. There was room to perform perfunctory pre-passage checks of the essential engineering, with access to the heavy-duty sea strainers and Racor fuel filters, the Onan to port, the air-con units behind, the hot-water service, and the fuel manifold back in the utility space or lazarette. With the engines back aft, the fuel is forward.

Outdoor/indoor living

As well as plenty of space outdoors, built-in and unobtrusive amenities for entertaining, and seats to kick back, there’s a huge hydraulic swim platform, a garage for a 3.2m tender, dual access to the big cockpit, transom lounge (with fabric upgrade) and teak table for eight.

Nearby are the electric barbecue/griddle, sink, and scope for fitting extra fridges and icemaker. There is a split sound system for the cockpit and another separate sound system with remote on the broad foredeck, which features a new double sunpad with flip-up headrest and recessed iceboxes that drain overboard.

There was an optional $6000 stainless steel anchor and, back at the transom, underwater lights. The new integrated anchor system, inboard rear cleats with hawsepipes, and sculptured transom contribute to the 5800 SY’s Euro lines. Yet the cockpit caters perfectly for our way of boating life and with the optional extended Euro awning, you will gain shade over the al fresco lunch setting.

Traced by generous Corian counters, and a new electric instead of manual awning window, the galley boasts four drawer-style fridges and freezers, Miele combination oven/microwave and grill, four-burner induction stove and dishwasher. The wetbar opposite has icemaker, glass and bottle storage, and soft-close drawers. Two bar stools front the forward return on the galley.

Easy-clean (optional) Amtico flooring flows forward to a portside dinette that’s big enough for six, with a hi/lo riser as per the cockpit table. Opposite is a popup Sony Bravia flatscreen television linked to the Bose AV system.

Side-opening windows flanking the helm, a big electric sunroof, and plenty of glass direct air and light inside.

Four-cabin beauty

The boat sleeps eight, with a VIP stateroom forward with lengthened island double bed, television and en suite; twin side-by-side single bunks that convert to a double to starboard, with access to an en suite that doubles as a dayhead; and, a portside cabin with bunks for kids or stowing gear.

The big gain, thanks to IPS, is the full-beam stateroom back aft, with king bed, settee, vanity, decent television, plenty of headroom and opening portlights. The bathrooms boast bigger showers and the latest push-button Vacuflush loos, plus improved plumbing. Storage space is abundant.

Drive time

There’s a black helm or co-pilot seat, carbon-fibre style automotive dash, and the usual spread of analogue engine gauges have been replaced with multifunction panels.

Besides the electronic Volvo engine panels, and C-Zone switching, there were twin Raymarine E120s linked to reversing and engineroom cameras. The sports wheel, EVC throttles and joystick controller fall to hand, with the option of a second joystick docking device in the cockpit. Noting excellent holeshot, we blasted 22kts at 3000rpm for 150lt/h. Advance the throttles and you will see 24.5kts at 3200rpm for 180lt/h, then a fast cruise of 27kts at 3400rpm for 195lt/h. Top speed was an impressive 38kts. Noise levels were pleasantly low.
