The Sea Ray 580 Sundancer 2012 vs Sea Ray Sundancer 470 2013 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 Sea Ray Sundancer 470 2013 measures 47,3 feet overall (2013), giving it roughly 41,3 additional feet of deck space compared to the Sea Ray 580 Sundancer 2012 at 6,0 feet (2012). Weight tells a clearer story for trailering families: the Sea Ray Sundancer 470 2013 tips the scales at 28 500 lbs — 27 965 lbs less than the Sea Ray 580 Sundancer 2012 at 535 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 1 051 hp, the Sea Ray 580 Sundancer 2012 has a 571-hp advantage over the Sea Ray Sundancer 470 2013's 480-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Sea Ray 580 Sundancer 2012 carries 825 gallons versus 35 gallons in the Sea Ray Sundancer 470 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
