Riviera Yachts 58 Enclosed Flybridge 2008 vs Riviera Yachts 85 Motor Yacht 2011 — Same Brand, Different Boat

Matching a modified vee Riviera Yachts 58 Enclosed Flybridge 2008 against a deep vee Riviera Yachts 85 Motor Yacht 2011 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

Size is the most obvious dividing line here. The Riviera Yachts 85 Motor Yacht 2011 measures 85,0 feet overall (2011), giving it roughly 26,0 additional feet of deck space compared to the Riviera Yachts 58 Enclosed Flybridge 2008 at 59,0 feet (2008). Weight tells a clearer story for trailering families: the Riviera Yachts 85 Motor Yacht 2011 tips the scales at 15 224 lbs — 14 563 lbs less than the Riviera Yachts 58 Enclosed Flybridge 2008 at 661 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.

The power gap is worth calling out. Rated to 2 030 hp, the Riviera Yachts 58 Enclosed Flybridge 2008 has a 810-hp advantage over the Riviera Yachts 85 Motor Yacht 2011's 1 220-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Riviera Yachts 58 Enclosed Flybridge 2008 carries 1 506 gallons versus 25 gallons in the Riviera Yachts 85 Motor Yacht 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Riviera Yachts 85 Motor Yacht 2011 is rated for 25 passengers, while the Riviera Yachts 58 Enclosed Flybridge 2008 caps at 18. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Riviera Yachts 85 Motor Yacht 2011 could be the deciding factor.

Bottom line: Choose the Riviera Yachts 85 Motor Yacht 2011 if your priority is putting more people on the water — it handles 25 passengers and at 85,0 ft it has the deck room to back that rating up comfortably. The Riviera Yachts 58 Enclosed Flybridge 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 18 that costs less to run day-to-day.
