The Riviera Yachts 4700 Sport Yacht 2008 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.

Size is the most obvious dividing line here. The Riviera Yachts 51 Flybridge 2007 measures 54,0 feet overall (2007), giving it roughly 49,0 additional feet of deck space compared to the Riviera Yachts 4700 Sport Yacht 2008 at 5,0 feet (2008).

The power gap is worth calling out. Rated to 1 400 hp, the Riviera Yachts 51 Flybridge 2007 has a 250-hp advantage over the Riviera Yachts 4700 Sport Yacht 2008's 1 150-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 51 Flybridge 2007 carries 713 gallons versus 634 gallons in the Riviera Yachts 4700 Sport Yacht 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
