Matching a deep vee Riviera Yachts 43 Open Flybridge 2011 against a modified vee Riviera Yachts 5800 Sport Yacht 2009 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 2009 measures 57,0 feet overall (2009), giving it roughly 12,3 additional feet of deck space compared to the Riviera Yachts 43 Open Flybridge 2011 at 44,7 feet (2011). Weight tells a clearer story for trailering families: the Riviera Yachts 5800 Sport Yacht 2009 tips the scales at 46 959 lbs — 46 646 lbs less than the Riviera Yachts 43 Open Flybridge 2011 at 313 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.

Both boats share a closely matched power ceiling — 435 hp for the Riviera Yachts 43 Open Flybridge 2011 and 435 hp for the Riviera Yachts 5800 Sport Yacht 2009. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Riviera Yachts 43 Open Flybridge 2011 carries 476 gallons versus 7 gallons in the Riviera Yachts 5800 Sport Yacht 2009. 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 2009 is rated for 17 passengers, while the Riviera Yachts 43 Open Flybridge 2011 caps at 13. 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 2009 could be the deciding factor.
