The Sea Ray 260 Sundeck 2013 vs Sea Ray Sundancer 340 1986 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 340 1986 measures 36,0 feet overall (1986), giving it roughly 9,7 additional feet of deck space compared to the Sea Ray 260 Sundeck 2013 at 26,3 feet (2013). Weight tells a clearer story for trailering families: the Sea Ray Sundancer 340 1986 tips the scales at 14 600 lbs — 9 432 lbs less than the Sea Ray 260 Sundeck 2013 at 5 168 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.

Both boats share a closely matched power ceiling — 300 hp for the Sea Ray 260 Sundeck 2013 and 320 hp for the Sea Ray Sundancer 340 1986. 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. Fuel capacity breaks the other way: the Sea Ray Sundancer 340 1986 carries 225 gallons versus 65 gallons in the Sea Ray 260 Sundeck 2013. 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 260 Sundeck 2013 is rated for 14 passengers, while the Sea Ray Sundancer 340 1986 caps at 10. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray 260 Sundeck 2013 could be the deciding factor.
