The Sea Ray 390 Sundancer 2011 vs Sea Ray Sedan 550 1996 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 550 1996 measures 56,1 feet overall (1996), giving it roughly 17,1 additional feet of deck space compared to the Sea Ray 390 Sundancer 2011 at 39,0 feet (2011). Weight tells a clearer story for trailering families: the Sea Ray Sedan 550 1996 tips the scales at 45 700 lbs — 45 454 lbs less than the Sea Ray 390 Sundancer 2011 at 246 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 power gap is worth calling out. Rated to 800 hp, the Sea Ray Sedan 550 1996 has a 375-hp advantage over the Sea Ray 390 Sundancer 2011's 425-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Sea Ray 390 Sundancer 2011 carries 25 gallons versus 7 gallons in the Sea Ray Sedan 550 1996. 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 Sedan 550 1996 is rated for 17 passengers, while the Sea Ray 390 Sundancer 2011 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray Sedan 550 1996 could be the deciding factor.
