When two boats share the same hull type — in this case both the Sea Ray 205 Sport 2013 and the Sea Ray 260 Sundancer 2013 are deep vee designs with fiberglass construction — the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?

Size is the most obvious dividing line here. The Sea Ray 260 Sundancer 2013 measures 26,6 feet overall (2013), giving it roughly 5,6 additional feet of deck space compared to the Sea Ray 205 Sport 2013 at 21,0 feet (2013). Weight tells a clearer story for trailering families: the Sea Ray 260 Sundancer 2013 tips the scales at 695 lbs — 380 lbs less than the Sea Ray 205 Sport 2013 at 315 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 — 260 hp for the Sea Ray 205 Sport 2013 and 260 hp for the Sea Ray 260 Sundancer 2013. 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 260 Sundancer 2013 carries 74 gallons versus 37 gallons in the Sea Ray 205 Sport 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 205 Sport 2013 is rated for 10 passengers, while the Sea Ray 260 Sundancer 2013 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 205 Sport 2013 could be the deciding factor.
