The Riviera 4600 Sport Yacht Platinum Edition 2022 vs Riviera Yachts 45 Open Flybridge Shaft Drive 2012 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 4600 Sport Yacht Platinum Edition 2022 at 50,3 ft versus Riviera Yachts 45 Open Flybridge Shaft Drive 2012 at 51,3 ft.

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 Shaft Drive 2012 has a 70-hp advantage over the Riviera 4600 Sport Yacht Platinum Edition 2022's 600-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
