The Sea Ray 220 Select 2007 vs Sea Ray 580 Sundancer 2011 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 2011 measures 60,0 feet overall (2011), giving it roughly 37,0 additional feet of deck space compared to the Sea Ray 220 Select 2007 at 23,0 feet (2007). Weight tells a clearer story for trailering families: the Sea Ray 580 Sundancer 2011 tips the scales at 53 500 lbs - 49 150 lbs less than the Sea Ray 220 Select 2007 at 4 350 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 2011 has a 731-hp advantage over the Sea Ray 220 Select 2007's 320-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 2011 carries 825 gallons versus 47 gallons in the Sea Ray 220 Select 2007. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

The Sea Ray 220 Select 2007 is rated for up to 10 people. Passenger data for the Sea Ray 580 Sundancer 2011 wasn't available.
