Riviera Yachts 45 Open Flybridge 2011 vs Riviera Yachts M470 Sport Cruiser 2008 — Same Brand, Different Boat

Matching a deep vee Riviera Yachts 45 Open Flybridge 2011 against a modified vee Riviera Yachts M470 Sport Cruiser 2008 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

On paper these two are close siblings in the size department — Riviera Yachts 45 Open Flybridge 2011 at 48,3 ft versus Riviera Yachts M470 Sport Cruiser 2008 at 47,0 ft. Weight tells a clearer story for trailering families: the Riviera Yachts 45 Open Flybridge 2011 tips the scales at 394 lbs — 372 lbs more than the Riviera Yachts M470 Sport Cruiser 2008 at 22 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 850 hp, the Riviera Yachts M470 Sport Cruiser 2008 has a 180-hp advantage over the Riviera Yachts 45 Open Flybridge 2011's 670-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 45 Open Flybridge 2011 carries 608 gallons versus 325 gallons in the Riviera Yachts M470 Sport Cruiser 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 14 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.

Bottom line: Performance buyers should lean toward the Riviera Yachts M470 Sport Cruiser 2008 and its 850-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Riviera Yachts 45 Open Flybridge 2011 with its 670-hp rating is the more economical daily driver.
