Matching a modified vee Sea Ray 300 Select EX 2008 against a semi displacement Sea Ray 580 Sedan Bridge 2012 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

The power gap is worth calling out. Rated to 861 hp, the Sea Ray 580 Sedan Bridge 2012 has a 541-hp advantage over the Sea Ray 300 Select EX 2008's 320-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Sea Ray 300 Select EX 2008 carries 13 gallons versus 7 gallons in the Sea Ray 580 Sedan Bridge 2012. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

For family outings this is probably the sharpest distinction between the two. The Sea Ray 580 Sedan Bridge 2012 is rated for 17 passengers, while the Sea Ray 300 Select EX 2008 caps at 8. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray 580 Sedan Bridge 2012 could be the deciding factor.
