The Riviera 395 SUV 2018 vs Riviera 78 Motor Yacht 2021 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 78 Motor Yacht 2021 measures 81,5 feet overall (2021), giving it roughly 37,9 additional feet of deck space compared to the Riviera 395 SUV 2018 at 43,6 feet (2018). Weight tells a clearer story for trailering families: the Riviera 395 SUV 2018 tips the scales at 27 778 lbs — 25 083 lbs more than the Riviera 78 Motor Yacht 2021 at 2 695 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 1 800 hp, the Riviera 78 Motor Yacht 2021 has a 1 360-hp advantage over the Riviera 395 SUV 2018's 440-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 78 Motor Yacht 2021 carries 2 695 gallons versus 396 gallons in the Riviera 395 SUV 2018. 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 78 Motor Yacht 2021 is rated for 24 passengers, while the Riviera 395 SUV 2018 caps at 13. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Riviera 78 Motor Yacht 2021 could be the deciding factor.
Bottom line: Choose the Riviera 78 Motor Yacht 2021 if your priority is putting more people on the water — it handles 24 passengers and at 81,5 ft it has the deck room to back that rating up comfortably. The Riviera 395 SUV 2018 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 13 that costs less to run day-to-day.
