Matching a deep vee Riviera Yachts 53 Enclosed 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.

On paper these two are close siblings in the size department — Riviera Yachts 53 Enclosed Flybridge 2011 at 56,4 ft versus Riviera Yachts 5800 Sport Yacht 2009 at 57,0 ft. Weight tells a clearer story for trailering families: the Riviera Yachts 5800 Sport Yacht 2009 tips the scales at 46 959 lbs — 42 043 lbs less than the Riviera Yachts 53 Enclosed Flybridge 2011 at 4 916 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 53 Enclosed 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 53 Enclosed Flybridge 2011 carries 925 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.

Both boats are rated for 17 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
