The Riviera 43 Open Flybridge 2021 vs Riviera Yachts 45 Open Flybridge 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.

On paper these two are close siblings in the size department — Riviera 43 Open Flybridge 2021 at 47,9 ft versus Riviera Yachts 45 Open Flybridge 2010 at 48,3 ft. Weight tells a clearer story for trailering families: the Riviera 43 Open Flybridge 2021 tips the scales at 33 030 lbs — 32 636 lbs more than the Riviera Yachts 45 Open Flybridge 2010 at 394 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 670 hp, the Riviera Yachts 45 Open Flybridge 2010 has a 230-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 Yachts 45 Open Flybridge 2010 carries 608 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.

Both boats are rated for 14 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
