Detailed Evaluation & Buyer Recommendation
Sea Ray 580 Sedan Bridge 2010 vs Sea Ray Sundancer 320 Outboard 2022 — Same Brand, Different Boat
The Sea Ray 580 Sedan Bridge 2010 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 861 hp, the Sea Ray 580 Sedan Bridge 2010 has a 611-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.
For family outings this is probably the sharpest distinction between the two. The Sea Ray 580 Sedan Bridge 2010 is rated for 17 passengers, while the Sea Ray Sundancer 320 Outboard 2022 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray 580 Sedan Bridge 2010 could be the deciding factor.
Bottom line: Choose the Sea Ray 580 Sedan Bridge 2010 if your priority is putting more people on the water — it handles 17 passengers and at 58,6 ft it has the deck room to back that rating up comfortably. The Sea Ray Sundancer 320 Outboard 2022 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.
