The Riviera 43 Open Flybridge 2021 vs Riviera Yachts 33 Open Flybridge SII 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.

Size is the most obvious dividing line here. The Riviera 43 Open Flybridge 2021 measures 47,9 feet overall (2021), giving it roughly 12,7 additional feet of deck space compared to the Riviera Yachts 33 Open Flybridge SII 2010 at 35,2 feet (2010).

Rated to 440 hp, the Riviera 43 Open Flybridge 2021 has a 70-hp advantage over the Riviera Yachts 33 Open Flybridge SII 2010's 370-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
