The Riviera Yachts 4700 Sport Yacht 2007 vs Riviera Yachts 70 Enclosed Flybridge 2011 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 70 Enclosed Flybridge 2011 measures 72,4 feet overall (2011), giving it roughly 67,4 additional feet of deck space compared to the Riviera Yachts 4700 Sport Yacht 2007 at 5,0 feet (2007).
