The Riviera 72 Sports Motor Yacht 2017 vs Riviera Yachts 5800 Sport Yacht 2010 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

Size is the most obvious dividing line here. The Riviera 72 Sports Motor Yacht 2017 measures 78,3 feet overall (2017), giving it roughly 20,7 additional feet of deck space compared to the Riviera Yachts 5800 Sport Yacht 2010 at 57,6 feet (2010). Weight tells a clearer story for trailering families: the Riviera 72 Sports Motor Yacht 2017 tips the scales at 120 361 lbs — 73 402 lbs more than the Riviera Yachts 5800 Sport Yacht 2010 at 46 959 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 255-hp advantage over the Riviera 72 Sports Motor Yacht 2017's 180-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 72 Sports Motor Yacht 2017 carries 2 695 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 72 Sports Motor Yacht 2017 is rated for 23 passengers, while the Riviera Yachts 5800 Sport Yacht 2010 caps at 17. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Riviera 72 Sports Motor Yacht 2017 could be the deciding factor.
