The Riviera 46 Sports Motor Yacht 2022 vs Riviera Yachts 51 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.

On paper these two are close siblings in the size department — Riviera 46 Sports Motor Yacht 2022 at 52,2 ft versus Riviera Yachts 51 Flybridge 2007 at 54,0 ft.
