Detailed Evaluation & Buyer Recommendation
Sea Ray 580 Sedan Bridge 2011 vs Sea Ray Sundancer 320 2022 — Same Brand, Different Boat
The Sea Ray 580 Sedan Bridge 2011 vs Sea Ray Sundancer 320 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 580 Sedan Bridge 2011 measures 58,6 feet overall (2011), giving it roughly 23,2 additional feet of deck space compared to the Sea Ray Sundancer 320 2022 at 35,4 feet (2022). Weight tells a clearer story for trailering families: the Sea Ray Sundancer 320 2022 tips the scales at 14 000 lbs — 13 485 lbs less than the Sea Ray 580 Sedan Bridge 2011 at 515 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 Sedan Bridge 2011 has a 561-hp advantage over the Sea Ray Sundancer 320 2022's 300-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 Sundancer 320 2022 carries 158 gallons versus 7 gallons in the Sea Ray 580 Sedan Bridge 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Sea Ray 580 Sedan Bridge 2011 is rated for 17 passengers, while the Sea Ray Sundancer 320 2022 caps at 10. 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 2011 could be the deciding factor.
Bottom line: Choose the Sea Ray 580 Sedan Bridge 2011 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 2022 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.
