Matching a deep vee Riviera Yachts 47 Enclosed Flybridge SII 2011 against a modified vee Riviera Yachts 58 Open Flybridge 2009 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 58 Open Flybridge 2009 measures 59,0 feet overall (2009), giving it roughly 9,9 additional feet of deck space compared to the Riviera Yachts 47 Enclosed Flybridge SII 2011 at 49,1 feet (2011).

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 1 015 hp, the Riviera Yachts 58 Open Flybridge 2009 has a 300-hp advantage over the Riviera Yachts 47 Enclosed Flybridge SII 2011's 715-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Riviera Yachts 58 Open Flybridge 2009 could be the deciding factor.
