Sea Ray 680 Sun Sport 2005 vs Sea Ray Sundancer 320 2022: Same Brand, Different Boat
The Sea Ray 680 Sun Sport 2005 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 680 Sun Sport 2005 measures 70,0 feet overall (2005), giving it roughly 34,6 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 680 Sun Sport 2005 tips the scales at 75 000 lbs - 61 000 lbs more than the Sea Ray Sundancer 320 2022 at 14 000 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 Sundancer 320 2022 tops out at 300 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 680 Sun Sport 2005 carries 1 000 gallons versus 158 gallons in the Sea Ray Sundancer 320 2022. 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 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 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 70,0 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.
