The Riviera Yachts 37 Open Flybridge 2009 vs Riviera Yachts 4700 Sport Yacht 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 37 Open Flybridge 2009 measures 39,0 feet overall (2009), giving it roughly 34,0 additional feet of deck space compared to the Riviera Yachts 4700 Sport Yacht 2007 at 5,0 feet (2007).
