The Riviera Yachts 47 Open Flybridge SII 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 47 Open Flybridge SII 2009 measures 49,0 feet overall (2009), giving it roughly 44,0 additional feet of deck space compared to the Riviera Yachts 4700 Sport Yacht 2007 at 5,0 feet (2007). Weight tells a clearer story for trailering families: the Riviera Yachts 47 Open Flybridge SII 2009 tips the scales at 432 lbs — 101 lbs more than the Riviera Yachts 4700 Sport Yacht 2007 at 331 lbs. 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 1 150 hp, the Riviera Yachts 4700 Sport Yacht 2007 has a 435-hp advantage over the Riviera Yachts 47 Open Flybridge SII 2009's 715-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 47 Open Flybridge SII 2009 carries 977 gallons versus 634 gallons in the Riviera Yachts 4700 Sport Yacht 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 15 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
