Detailed Evaluation & Buyer Recommendation
Sea Ray 580 Sundancer 2011 vs Sea Ray Sundancer 320 Outboard 2022 — Same Brand, Different Boat
The Sea Ray 580 Sundancer 2011 vs Sea Ray Sundancer 320 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.
The power gap is worth calling out. Rated to 1 051 hp, the Sea Ray 580 Sundancer 2011 has a 801-hp advantage over the Sea Ray Sundancer 320 Outboard 2022's 250-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
Bottom line: The Sea Ray Sundancer 320 Outboard 2022 at 32,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Sea Ray 580 Sundancer 2011 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.
