Riviera Yachts 38 Open Flybridge 2011 vs Riviera Yachts 5800 Sport Yacht 2010 — Same Brand, Different Boat

Matching a deep vee Riviera Yachts 38 Open Flybridge 2011 against a modified vee Riviera Yachts 5800 Sport Yacht 2010 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 5800 Sport Yacht 2010 measures 57,6 feet overall (2010), giving it roughly 18,2 additional feet of deck space compared to the Riviera Yachts 38 Open Flybridge 2011 at 39,4 feet (2011). Weight tells a clearer story for trailering families: the Riviera Yachts 5800 Sport Yacht 2010 tips the scales at 46 959 lbs — 46 935 lbs less than the Riviera Yachts 38 Open Flybridge 2011 at 24 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 435 hp, the Riviera Yachts 5800 Sport Yacht 2010 has a 65-hp advantage over the Riviera Yachts 38 Open Flybridge 2011's 370-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 38 Open Flybridge 2011 carries 38 gallons versus 7 gallons in the Riviera Yachts 5800 Sport Yacht 2010. 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 5800 Sport Yacht 2010 is rated for 17 passengers, while the Riviera Yachts 38 Open Flybridge 2011 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Riviera Yachts 5800 Sport Yacht 2010 could be the deciding factor.

Bottom line: Choose the Riviera Yachts 5800 Sport Yacht 2010 if your priority is putting more people on the water — it handles 17 passengers and at 57,6 ft it has the deck room to back that rating up comfortably. The Riviera Yachts 38 Open Flybridge 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 12 that costs less to run day-to-day.
