Detailed Evaluation & Buyer Recommendation
Sea Ray 580 Sundancer 2013 vs Sea Ray Sundancer 350 2020 — Same Brand, Different Boat
The Sea Ray 580 Sundancer 2013 vs Sea Ray Sundancer 350 2020 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 350 2020 measures 35,0 feet overall (2020), giving it roughly 29,0 additional feet of deck space compared to the Sea Ray 580 Sundancer 2013 at 6,0 feet (2013). Weight tells a clearer story for trailering families: the Sea Ray Sundancer 350 2020 tips the scales at 15 780 lbs — 15 245 lbs less than the Sea Ray 580 Sundancer 2013 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 861 hp, the Sea Ray 580 Sundancer 2013 has a 511-hp advantage over the Sea Ray Sundancer 350 2020'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 2013 carries 825 gallons versus 23 gallons in the Sea Ray Sundancer 350 2020. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Bottom line: The Sea Ray Sundancer 350 2020 at 35,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Sea Ray 580 Sundancer 2013 at 6,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
