Detailed Evaluation & Buyer Recommendation
Sea Ray 680 Sun Sport 2005 vs Sea Ray Sedan Bridge 450 2012 — Same Brand, Different Boat
The Sea Ray 680 Sun Sport 2005 vs Sea Ray Sedan Bridge 450 2012 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 Sedan Bridge 450 2012 measures 45,0 feet overall (2012), giving it roughly 38,0 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 Sedan Bridge 450 2012 tips the scales at 36 602 lbs — 36 527 lbs less 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 Sedan Bridge 450 2012 tops out at 480 hp. Engine specs for the Sea Ray 680 Sun Sport 2005 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Sea Ray Sedan Bridge 450 2012 carries 375 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 Sedan Bridge 450 2012 caps at 13. 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 Sedan Bridge 450 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 13 that costs less to run day-to-day.
