Matching a modified vee Riviera Yachts 37 Open Flybridge 2009 against a deep vee Riviera Yachts 63 Enclosed Flybridge 2012 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 63 Enclosed Flybridge 2012 measures 64,4 feet overall (2012), giving it roughly 25,4 additional feet of deck space compared to the Riviera Yachts 37 Open Flybridge 2009 at 39,0 feet (2009). Weight tells a clearer story for trailering families: the Riviera Yachts 63 Enclosed Flybridge 2012 tips the scales at 672 lbs — 648 lbs less than the Riviera Yachts 37 Open Flybridge 2009 at 24 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 1 015 hp, the Riviera Yachts 63 Enclosed Flybridge 2012 has a 645-hp advantage over the Riviera Yachts 37 Open Flybridge 2009's 370-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 63 Enclosed Flybridge 2012 could be the deciding factor.
