Sea Ray 320 Sundancer 2005 vs Sea Ray 47 Sedan Bridge 2011 — Same Brand, Different Boat
The Sea Ray 320 Sundancer 2005 vs Sea Ray 47 Sedan Bridge 2011 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 47 Sedan Bridge 2011 measures 50,7 feet overall (2011), giving it roughly 15,7 additional feet of deck space compared to the Sea Ray 320 Sundancer 2005 at 35,0 feet (2005). Weight tells a clearer story for trailering families: the Sea Ray 47 Sedan Bridge 2011 tips the scales at 375 lbs — 237 lbs less than the Sea Ray 320 Sundancer 2005 at 138 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 47 Sedan Bridge 2011 tops out at 574 hp. Engine specs for the Sea Ray 320 Sundancer 2005 aren't listed — confirm with a dealer before selecting an outboard.Fuel capacity breaks the other way: the Sea Ray 47 Sedan Bridge 2011 carries 53 gallons versus 2 gallons in the Sea Ray 320 Sundancer 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 47 Sedan Bridge 2011 is rated for 15 passengers, while the Sea Ray 320 Sundancer 2005 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 47 Sedan Bridge 2011 could be the deciding factor.
Bottom line: Choose the Sea Ray 47 Sedan Bridge 2011 if your priority is putting more people on the water — it handles 15 passengers and at 50,7 ft it has the deck room to back that rating up comfortably. The Sea Ray 320 Sundancer 2005 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 10 that costs less to run day-to-day.
