About this tender
The Riva 68' Diable is the open we'd put alongside the best Italian production builds at this length - a 20.67m hull carrying sixteen people aboard, powered by a choice of twin MAN V12 units in either 1,550 hp or 1,650 hp configuration. The lower option returns a verified 37 knots maximum with a 260 nm cruising range; step up to the 1,650 hp engines and the top end moves to 40 knots, still at a credible 250 nm range. Those are manufacturer-published figures from Riva's own technical specification sheet.
Below decks the Diable runs three guest cabins plus a dedicated crew cabin - an arrangement that makes sense on a yacht of this size, where owners are often running the boat as a principal vessel on Med or Atlantic programmes rather than as a tender. Unladen displacement is 37,000 kg, laden 44,000 kg; 3,800 litres of fuel capacity supports meaningful range without a mothership nearby. The build sits within the Ferretti Group, which brings group engineering resource and documented production discipline to the fit-out.
Where the Diable sits in your programme depends on what you need from an open boat at this length. The twin-V12 driveline gives point-to-point speed that puts serious distance behind you; the cabin arrangement means the boat can accommodate guests independently of a support vessel. We'd consider it carefully for programmes where the 68-foot open format is the right tool, and where the Riva name carries value with owners who know the brand.
Highlights
The four details we'd point out first to a captain who hasn't seen one on the water yet.
Riva offers two engine variants for the 68' Diable: the MAN V12 1550, delivering 37 knots maximum and 260 nm range at cruising speed, and the MAN V12 1650, which pushes the ceiling to 40 knots with a 250 nm cruising range. Both options use the same hull and layout configuration. The choice of variant depends on whether your programme prioritises range or top-end speed.
The lower deck accommodates three guest cabins and a separate crew cabin. For a 20.67m open yacht, that is a practical and well-resolved arrangement - enough private space for a small owner party to run independently, without requiring a support vessel for overnight passages.
Manufacturer specification lists sixteen people on board across both engine variants. That figure covers day use with a full guest complement, and is the number to cross-reference against your flag state and certification requirements when planning coastal or offshore passages.
With 3,800 litres of fuel, the Diable carries enough to sustain cruising-speed passages of 250 to 260 nm depending on engine choice - without needing to plan fuel stops on typical Mediterranean or Caribbean day routes. Water capacity is 600 litres, sized for overnight use rather than extended liveaboard passages.
