Riviera 445 SUV 2022 vs Riviera Yachts 51 Enclosed Flybridge 2007 — Same Brand, Different Boat

The Riviera 445 SUV 2022 vs Riviera Yachts 51 Enclosed Flybridge 2007 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 Yachts 51 Enclosed Flybridge 2007 measures 54,0 feet overall (2007), giving it roughly 6,1 additional feet of deck space compared to the Riviera 445 SUV 2022 at 47,9 feet (2022). Weight tells a clearer story for trailering families: the Riviera 445 SUV 2022 tips the scales at 29 762 lbs — 29 244 lbs more than the Riviera Yachts 51 Enclosed Flybridge 2007 at 518 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 1 400 hp, the Riviera Yachts 51 Enclosed Flybridge 2007 has a 960-hp advantage over the Riviera 445 SUV 2022'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 Yachts 51 Enclosed Flybridge 2007 carries 713 gallons versus 528 gallons in the Riviera 445 SUV 2022. 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 51 Enclosed Flybridge 2007 is rated for 16 passengers, while the Riviera 445 SUV 2022 caps at 14. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Riviera Yachts 51 Enclosed Flybridge 2007 could be the deciding factor.

Bottom line: Choose the Riviera Yachts 51 Enclosed Flybridge 2007 if your priority is putting more people on the water — it handles 16 passengers and at 54,0 ft it has the deck room to back that rating up comfortably. The Riviera 445 SUV 2022 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 14 that costs less to run day-to-day.

Riviera 445 SUV 2022 vs Riviera Yachts 51 Enclosed Flybridge 2007 — Common Questions

Which is the larger boat — the Riviera 445 SUV 2022 or the Riviera Yachts 51 Enclosed Flybridge 2007?
The Riviera Yachts 51 Enclosed Flybridge 2007 is the longer of the two at 54,0 feet overall. The Riviera 445 SUV 2022 comes in at 47,9 feet, making it roughly 6,1 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Riviera 445 SUV 2022 or the Riviera Yachts 51 Enclosed Flybridge 2007?
For trailering, the Riviera Yachts 51 Enclosed Flybridge 2007 has the edge at 518 lbs dry weight versus 29 762 lbs for the Riviera 445 SUV 2022. 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 Yachts 51 Enclosed Flybridge 2007 is rated to a maximum of 1 400 hp, giving it the larger power ceiling. The Riviera 445 SUV 2022 tops out at 440 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 445 SUV 2022 is Coast Guard rated for 14 passengers, while the Riviera Yachts 51 Enclosed Flybridge 2007 is certified for 16. 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 51 Enclosed Flybridge 2007 measures 194" wide, compared to 180" for the Riviera 445 SUV 2022. 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 445 SUV 2022 or the Riviera Yachts 51 Enclosed Flybridge 2007?
The Riviera Yachts 51 Enclosed Flybridge 2007 has the bigger tank at 713 gallons, versus 528 gallons on the Riviera 445 SUV 2022. That 185-gallon difference translates to roughly 555–925 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Riviera 445 SUV 2022 and Riviera Yachts 51 Enclosed Flybridge 2007 from the same manufacturer?
Yes — both the Riviera 445 SUV 2022 and the Riviera Yachts 51 Enclosed Flybridge 2007 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.
