The Sea Ray 185 Sport 2011 is a modified-V design and the Sea Ray 310 Sundancer 2008 is a deep-V design, so you're likely deciding between two noticeably 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 310 Sundancer 2008 measures 33,0 feet overall (2008), giving it roughly 13,3 additional feet of deck space compared to the Sea Ray 185 Sport 2011 at 19,7 feet (2011). Weight tells a clearer story for trailering families: the Sea Ray 310 Sundancer 2008 tips the scales at 14 000 lbs - 11 400 lbs less than the Sea Ray 185 Sport 2011 at 2 600 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 320 hp, the Sea Ray 310 Sundancer 2008 has a 100-hp advantage over the Sea Ray 185 Sport 2011's 220-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 310 Sundancer 2008 carries 200 gallons versus 26 gallons in the Sea Ray 185 Sport 2011. 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 310 Sundancer 2008 is rated for 10 passengers, while the Sea Ray 185 Sport 2011 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 310 Sundancer 2008 could be the deciding factor.
