When two boats share the same hull type — in this case both the Sea Ray 52 Sedan Bridge 2009 and the Sea Ray 580 Sedan Bridge 2012 are semi displacement designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

On paper these two are close siblings in the size department — Sea Ray 52 Sedan Bridge 2009 at 57,1 ft versus Sea Ray 580 Sedan Bridge 2012 at 58,6 ft. Weight tells a clearer story for trailering families: the Sea Ray 52 Sedan Bridge 2009 tips the scales at 40 267 lbs — 39 752 lbs more than the Sea Ray 580 Sedan Bridge 2012 at 515 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 580 Sedan Bridge 2012 has a 96-hp advantage over the Sea Ray 52 Sedan Bridge 2009's 765-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 7 gal — so range won't be a tiebreaker here.

Both boats are rated for 17 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.
