Riviera 78 Motor Yacht 2021 vs Riviera Yachts 75 Enclosed Flybridge Shaft Drive 2012 — Same Brand, Different Boat

The Riviera 78 Motor Yacht 2021 vs Riviera Yachts 75 Enclosed Flybridge Shaft Drive 2012 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.

On paper these two are close siblings in the size department — Riviera 78 Motor Yacht 2021 at 81,5 ft versus Riviera Yachts 75 Enclosed Flybridge Shaft Drive 2012 at 80,3 ft. Weight tells a clearer story for trailering families: the Riviera Yachts 75 Enclosed Flybridge Shaft Drive 2012 tips the scales at 92 418 lbs — 89 723 lbs less 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 228-hp advantage over the Riviera Yachts 75 Enclosed Flybridge Shaft Drive 2012's 1 572-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 238 gallons in the Riviera Yachts 75 Enclosed Flybridge Shaft Drive 2012. 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 Yachts 75 Enclosed Flybridge Shaft Drive 2012 caps at 23. 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 Yachts 75 Enclosed Flybridge Shaft Drive 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 23 that costs less to run day-to-day.

Riviera 78 Motor Yacht 2021 vs Riviera Yachts 75 Enclosed Flybridge Shaft Drive 2012 — Common Questions

Which is the larger boat — the Riviera 78 Motor Yacht 2021 or the Riviera Yachts 75 Enclosed Flybridge Shaft Drive 2012?
The Riviera 78 Motor Yacht 2021 is the longer of the two at 81,5 feet overall. The Riviera Yachts 75 Enclosed Flybridge Shaft Drive 2012 comes in at 80,3 feet, making it roughly 1,3 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Riviera 78 Motor Yacht 2021 or the Riviera Yachts 75 Enclosed Flybridge Shaft Drive 2012?
For trailering, the Riviera 78 Motor Yacht 2021 has the edge at 2 695 lbs dry weight versus 92 418 lbs for the Riviera Yachts 75 Enclosed Flybridge Shaft Drive 2012. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Riviera 78 Motor Yacht 2021 is rated to a maximum of 1 800 hp, giving it the larger power ceiling. The Riviera Yachts 75 Enclosed Flybridge Shaft Drive 2012 tops out at 1 572 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.
How many people can each boat hold?
The Riviera 78 Motor Yacht 2021 is Coast Guard rated for 24 passengers, while the Riviera Yachts 75 Enclosed Flybridge Shaft Drive 2012 is certified for 23. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.
Which boat is wider, and does it affect trailering?
The Riviera Yachts 75 Enclosed Flybridge Shaft Drive 2012 measures 249" wide, compared to 238" for the Riviera 78 Motor Yacht 2021. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank — the Riviera 78 Motor Yacht 2021 or the Riviera Yachts 75 Enclosed Flybridge Shaft Drive 2012?
The Riviera 78 Motor Yacht 2021 has the bigger tank at 2 695 gallons, versus 238 gallons on the Riviera Yachts 75 Enclosed Flybridge Shaft Drive 2012. That 2457-gallon difference translates to roughly 7371–12285 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Yes — both the Riviera 78 Motor Yacht 2021 and the Riviera Yachts 75 Enclosed Flybridge Shaft Drive 2012 are built by Riviera Yachts. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.
