Detailed Evaluation & Buyer Recommendation
Sea Ray 580 Sedan Bridge 2013 vs Sea Ray 680 Sun Sport 2005 — Same Brand, Different Boat
The Sea Ray 580 Sedan Bridge 2013 vs Sea Ray 680 Sun Sport 2005 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 2013 measures 58,6 feet overall (2013), giving it roughly 51,6 additional feet of deck space compared to the Sea Ray 680 Sun Sport 2005 at 7,0 feet (2005). Weight tells a clearer story for trailering families: the Sea Ray 580 Sedan Bridge 2013 tips the scales at 515 lbs — 440 lbs more than the Sea Ray 680 Sun Sport 2005 at 75 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 Sea Ray 580 Sedan Bridge 2013 carries a rated maximum of 861 hp. Engine data for the Sea Ray 680 Sun Sport 2005 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Sea Ray 580 Sedan Bridge 2013 carries 7 gallons versus 1 gallons in the Sea Ray 680 Sun Sport 2005. 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 680 Sun Sport 2005 is rated for 21 passengers, while the Sea Ray 580 Sedan Bridge 2013 caps at 17. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray 680 Sun Sport 2005 could be the deciding factor.
Bottom line: Choose the Sea Ray 680 Sun Sport 2005 if your priority is putting more people on the water — it handles 21 passengers and at 7,0 ft it has the deck room to back that rating up comfortably. The Sea Ray 580 Sedan Bridge 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 17 that costs less to run day-to-day.
