The Sea Ray 580 Sundancer 2011 vs Sea Ray SLX 350 Outboard 2022 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 SLX 350 Outboard 2022 measures 34,7 feet overall (2022), giving it roughly 28,7 additional feet of deck space compared to the Sea Ray 580 Sundancer 2011 at 6,0 feet (2011). Weight tells a clearer story for trailering families: the Sea Ray SLX 350 Outboard 2022 tips the scales at 12 060 lbs — 11 525 lbs less than the Sea Ray 580 Sundancer 2011 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 2011 has a 701-hp advantage over the Sea Ray SLX 350 Outboard 2022's 350-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 177 gallons in the Sea Ray SLX 350 Outboard 2022. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
