The Sea Ray 390 Sundancer 2012 vs Sea Ray 52 Sedan Bridge 2007 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 52 Sedan Bridge 2007 measures 52,0 feet overall (2007), giving it roughly 13,0 additional feet of deck space compared to the Sea Ray 390 Sundancer 2012 at 39,0 feet (2012). Weight tells a clearer story for trailering families: the Sea Ray 52 Sedan Bridge 2007 tips the scales at 367 lbs — 121 lbs less than the Sea Ray 390 Sundancer 2012 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 765 hp, the Sea Ray 52 Sedan Bridge 2007 has a 340-hp advantage over the Sea Ray 390 Sundancer 2012'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 2012 carries 25 gallons versus 5 gallons in the Sea Ray 52 Sedan Bridge 2007. 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 52 Sedan Bridge 2007 is rated for 15 passengers, while the Sea Ray 390 Sundancer 2012 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 52 Sedan Bridge 2007 could be the deciding factor.
