The Sea Ray Sundancer 320 Outboard 2023 vs Sea Ray Sundancer 380 2003 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 Sundancer 380 2003 measures 42,0 feet overall (2003), giving it roughly 7,9 additional feet of deck space compared to the Sea Ray Sundancer 320 Outboard 2023 at 34,1 feet (2023). Weight tells a clearer story for trailering families: the Sea Ray Sundancer 380 2003 tips the scales at 20 000 lbs - 6 319 lbs less than the Sea Ray Sundancer 320 Outboard 2023 at 13 681 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.
Both boats share a closely matched power ceiling - 350 hp for the Sea Ray Sundancer 320 Outboard 2023 and 350 hp for the Sea Ray Sundancer 380 2003. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Sea Ray Sundancer 380 2003 carries 275 gallons versus 158 gallons in the Sea Ray Sundancer 320 Outboard 2023. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray Sundancer 380 2003 could be the deciding factor.
Bottom line: Choose the Sea Ray Sundancer 380 2003 if your priority is putting more people on the water - it handles 12 passengers and at 42,0 ft it has the deck room to back that rating up comfortably. The Sea Ray Sundancer 320 Outboard 2023 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.
