When two boats share the same hull type — in this case both the Sea Ray 58 Sedan Bridge 2009 and the Sea Ray 580 Sedan Bridge 2011 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 58 Sedan Bridge 2009 at 58,6 ft versus Sea Ray 580 Sedan Bridge 2011 at 58,6 ft. At 515 lbs and 515 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

Both boats share a closely matched power ceiling — 861 hp for the Sea Ray 58 Sedan Bridge 2009 and 861 hp for the Sea Ray 580 Sedan Bridge 2011. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Both carry nearly identical fuel loads — 7 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.
