The Riviera 54 Open Flybridge 2021 vs Riviera Yachts 3600 Sport Yacht 2010 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 54 Open Flybridge 2021 measures 57,9 feet overall (2021), giving it roughly 19,4 additional feet of deck space compared to the Riviera Yachts 3600 Sport Yacht 2010 at 38,5 feet (2010). Weight tells a clearer story for trailering families: the Riviera 54 Open Flybridge 2021 tips the scales at 58 030 lbs — 38 409 lbs more than the Riviera Yachts 3600 Sport Yacht 2010 at 19 621 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 725 hp, the Riviera 54 Open Flybridge 2021 has a 424-hp advantage over the Riviera Yachts 3600 Sport Yacht 2010's 301-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 54 Open Flybridge 2021 carries 925 gallons versus 212 gallons in the Riviera Yachts 3600 Sport Yacht 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 54 Open Flybridge 2021 is rated for 17 passengers, while the Riviera Yachts 3600 Sport Yacht 2010 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Riviera 54 Open Flybridge 2021 could be the deciding factor.
