Sea Ray 480 Motor Yacht 2005 vs Sea Ray 520 Sedan Bridge 2011 — Same Brand, Different Boat

The Sea Ray 480 Motor Yacht 2005 vs Sea Ray 520 Sedan Bridge 2011 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 520 Sedan Bridge 2011 measures 52,3 feet overall (2011), giving it roughly 47,3 additional feet of deck space compared to the Sea Ray 480 Motor Yacht 2005 at 5,0 feet (2005). Weight tells a clearer story for trailering families: the Sea Ray 480 Motor Yacht 2005 tips the scales at 385 lbs — 343 lbs more than the Sea Ray 520 Sedan Bridge 2011 at 42 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 Sea Ray 520 Sedan Bridge 2011 tops out at 764 hp. Engine specs for the Sea Ray 480 Motor Yacht 2005 aren't listed — confirm with a dealer before selecting an outboard.Both carry nearly identical fuel loads — 5 gal and 5 gal — so range won't be a tiebreaker here.

Both boats are rated for 15 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

Bottom line: The Sea Ray 520 Sedan Bridge 2011 at 52,3 ft is the right call if deck space, comfort, and entertaining are top of your list. The Sea Ray 480 Motor Yacht 2005 at 5,0 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.

For trailering, the Sea Ray 520 Sedan Bridge 2011 has the edge at 42 lbs dry weight versus 385 lbs for the Sea Ray 480 Motor Yacht 2005.

(4.65 m) beam — meaning both sit right at the 8’6" threshold that most US states use for standard-width loads. In most states you can tow at that width without a special permit, but regulations vary.
