Sea Ray 450 Sedan Bridge 2013 vs Sea Ray 55 Sundancer 2007 — Same Brand, Different Boat

The Sea Ray 450 Sedan Bridge 2013 vs Sea Ray 55 Sundancer 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 450 Sedan Bridge 2013 measures 45,6 feet overall (2013), giving it roughly 39,6 additional feet of deck space compared to the Sea Ray 55 Sundancer 2007 at 6,0 feet (2007). Weight tells a clearer story for trailering families: the Sea Ray 450 Sedan Bridge 2013 tips the scales at 36 602 lbs — 36 549 lbs more than the Sea Ray 55 Sundancer 2007 at 53 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 861 hp, the Sea Ray 55 Sundancer 2007 has a 381-hp advantage over the Sea Ray 450 Sedan Bridge 2013's 480-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 375 gallons in the Sea Ray 450 Sedan Bridge 2013. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

The Sea Ray 450 Sedan Bridge 2013 is rated for up to 13 people. Passenger data for the Sea Ray 55 Sundancer 2007 wasn't available.

Bottom line: The Sea Ray 450 Sedan Bridge 2013 at 45,6 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.

The Sea Ray 450 Sedan Bridge 2013 is the longer of the two at 45,6 feet overall. The Sea Ray 55 Sundancer 2007 comes in at 6,0 feet, making it roughly 39,6 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Sea Ray 450 Sedan Bridge 2013 or the Sea Ray 55 Sundancer 2007?
For trailering, the Sea Ray 55 Sundancer 2007 has the edge at 53 lbs dry weight versus 36 602 lbs for the Sea Ray 450 Sedan Bridge 2013. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.

The Sea Ray 55 Sundancer 2007 is rated to a maximum of 861 hp, giving it the larger power ceiling. The Sea Ray 450 Sedan Bridge 2013 tops out at 480 hp.
