The Sea Ray 260 Sundancer 2012 vs Sea Ray Sundancer 310 2011 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.

Size is the most obvious dividing line here. The Sea Ray Sundancer 310 2011 measures 31,0 feet overall (2011), giving it roughly 4,4 additional feet of deck space compared to the Sea Ray 260 Sundancer 2012 at 26,6 feet (2012). Weight tells a clearer story for trailering families: the Sea Ray Sundancer 310 2011 tips the scales at 11 630 lbs — 10 935 lbs less than the Sea Ray 260 Sundancer 2012 at 695 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 300 hp, the Sea Ray 260 Sundancer 2012 has a 40-hp advantage over the Sea Ray Sundancer 310 2011's 260-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 Sundancer 310 2011 carries 125 gallons versus 75 gallons in the Sea Ray 260 Sundancer 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 Sundancer 310 2011 is rated for 9 passengers, while the Sea Ray 260 Sundancer 2012 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 Sundancer 310 2011 could be the deciding factor.
