Sea Ray 55 Sundancer 2007 vs Sea Ray Sedan Bridge 390 2010 — Same Brand, Different Boat

The Sea Ray 55 Sundancer 2007 vs Sea Ray Sedan Bridge 390 2010 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.

The power gap is worth calling out. Rated to 861 hp, the Sea Ray 55 Sundancer 2007 has a 481-hp advantage over the Sea Ray Sedan Bridge 390 2010's 380-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 55 Sundancer 2007 carries 825 gallons versus 3 gallons in the Sea Ray Sedan Bridge 390 2010. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Bottom line: The Sea Ray Sedan Bridge 390 2010 at 39,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Sea Ray 55 Sundancer 2007 at 6,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
