The Sea Ray 185 Sport 2007 vs Sea Ray 580 Sundancer 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 580 Sundancer 2013 measures 60,0 feet overall (2013), giving it roughly 41,0 additional feet of deck space compared to the Sea Ray 185 Sport 2007 at 19,0 feet (2007). Weight tells a clearer story for trailering families: the Sea Ray 580 Sundancer 2013 tips the scales at 53 500 lbs - 51 100 lbs less than the Sea Ray 185 Sport 2007 at 2 400 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 861 hp, the Sea Ray 580 Sundancer 2013 has a 671-hp advantage over the Sea Ray 185 Sport 2007's 190-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 2013 carries 825 gallons versus 26 gallons in the Sea Ray 185 Sport 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
