Matching a modified vee Sea Ray 185 Sport 2008 against a semi displacement Sea Ray 580 Sundancer 2011 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.

Size is the most obvious dividing line here. The Sea Ray 185 Sport 2008 measures 19,0 feet overall (2008), giving it roughly 13,0 additional feet of deck space compared to the Sea Ray 580 Sundancer 2011 at 6,0 feet (2011). Weight tells a clearer story for trailering families: the Sea Ray 580 Sundancer 2011 tips the scales at 535 lbs — 509 lbs less than the Sea Ray 185 Sport 2008 at 26 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 1 051 hp, the Sea Ray 580 Sundancer 2011 has a 1 047-hp advantage over the Sea Ray 185 Sport 2008's 4-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 580 Sundancer 2011 carries 825 gallons versus 26 gallons in the Sea Ray 185 Sport 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

The Sea Ray 185 Sport 2008 is rated for up to 8 people. Passenger data for the Sea Ray 580 Sundancer 2011 wasn't available.
