Riviera Yachts 45 Open Flybridge 2010 vs Riviera Yachts 73 Motor Yacht with Volvo Penta IPS 2011 — Same Brand, Different Boat

Matching a modified vee Riviera Yachts 45 Open Flybridge 2010 against a deep vee Riviera Yachts 73 Motor Yacht with Volvo Penta IPS 2011 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.

Size is the most obvious dividing line here. The Riviera Yachts 73 Motor Yacht with Volvo Penta IPS 2011 measures 73,5 feet overall (2011), giving it roughly 25,3 additional feet of deck space compared to the Riviera Yachts 45 Open Flybridge 2010 at 48,3 feet (2010). Weight tells a clearer story for trailering families: the Riviera Yachts 73 Motor Yacht with Volvo Penta IPS 2011 tips the scales at 11 022 lbs — 10 628 lbs less than the Riviera Yachts 45 Open Flybridge 2010 at 394 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 835 hp, the Riviera Yachts 73 Motor Yacht with Volvo Penta IPS 2011 has a 165-hp advantage over the Riviera Yachts 45 Open Flybridge 2010'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 73 Motor Yacht with Volvo Penta IPS 2011 carries 2 117 gallons versus 608 gallons in the Riviera Yachts 45 Open Flybridge 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Riviera Yachts 73 Motor Yacht with Volvo Penta IPS 2011 is rated for 22 passengers, while the Riviera Yachts 45 Open Flybridge 2010 caps at 14. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Riviera Yachts 73 Motor Yacht with Volvo Penta IPS 2011 could be the deciding factor.

Bottom line: Choose the Riviera Yachts 73 Motor Yacht with Volvo Penta IPS 2011 if your priority is putting more people on the water — it handles 22 passengers and at 73,5 ft it has the deck room to back that rating up comfortably. The Riviera Yachts 45 Open Flybridge 2010 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 14 that costs less to run day-to-day.
