Detailed Evaluation & Buyer Recommendation
Sea Ray 520 Sedan Bridge 2011 vs Sea Ray Sundancer 500 1996 — Same Brand, Different Boat
The Sea Ray 520 Sedan Bridge 2011 vs Sea Ray Sundancer 500 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.
On paper these two are close siblings in the size department — Sea Ray 520 Sedan Bridge 2011 at 52,3 ft versus Sea Ray Sundancer 500 1996 at 50,0 ft. Weight tells a clearer story for trailering families: the Sea Ray Sundancer 500 1996 tips the scales at 34 500 lbs — 34 458 lbs less 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 power gap is worth calling out. Rated to 764 hp, the Sea Ray 520 Sedan Bridge 2011 has a 29-hp advantage over the Sea Ray Sundancer 500 1996's 735-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. 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 Sundancer 500 1996 at 50,0 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.
