The Riviera 43 Open Flybridge 2021 vs Riviera Belize 66 Sedan 2019 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 Belize 66 Sedan 2019 measures 69,3 feet overall (2019), giving it roughly 21,4 additional feet of deck space compared to the Riviera 43 Open Flybridge 2021 at 47,9 feet (2021). Weight tells a clearer story for trailering families: the Riviera Belize 66 Sedan 2019 tips the scales at 77 195 lbs — 44 165 lbs less than the Riviera 43 Open Flybridge 2021 at 33 030 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 1 000 hp, the Riviera Belize 66 Sedan 2019 has a 560-hp advantage over the Riviera 43 Open Flybridge 2021'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 Belize 66 Sedan 2019 carries 1 188 gallons versus 528 gallons in the Riviera 43 Open Flybridge 2021. 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 Belize 66 Sedan 2019 is rated for 21 passengers, while the Riviera 43 Open Flybridge 2021 caps at 14. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Riviera Belize 66 Sedan 2019 could be the deciding factor.
