The Sea Ray 520 Sedan Bridge 2012 vs Sea Ray Sundancer 510 2002 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 2012 at 52,3 ft versus Sea Ray Sundancer 510 2002 at 51,0 ft. Weight tells a clearer story for trailering families: the Sea Ray Sundancer 510 2002 tips the scales at 38 500 lbs — 38 458 lbs less than the Sea Ray 520 Sedan Bridge 2012 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 2012 has a 104-hp advantage over the Sea Ray Sundancer 510 2002's 660-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 6 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.
