The Sea Ray 390 Sedan Bridge 2011 vs Sea Ray 48 Sundancer 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 48 Sundancer 2005 measures 51,0 feet overall (2005), giving it roughly 10,3 additional feet of deck space compared to the Sea Ray 390 Sedan Bridge 2011 at 40,8 feet (2011). At 22 lbs and 28 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
The Sea Ray 390 Sedan Bridge 2011 carries a rated maximum of 375 hp. Engine data for the Sea Ray 48 Sundancer 2005 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Both carry nearly identical fuel loads — 3 gal and 4 gal — so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Sea Ray 48 Sundancer 2005 is rated for 15 passengers, while the Sea Ray 390 Sedan Bridge 2011 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray 48 Sundancer 2005 could be the deciding factor.
Bottom line: Choose the Sea Ray 48 Sundancer 2005 if your priority is putting more people on the water — it handles 15 passengers and at 51,0 ft it has the deck room to back that rating up comfortably. The Sea Ray 390 Sedan Bridge 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 12 that costs less to run day-to-day.
