The Sea Ray 290 Sundancer 2006 vs Sea Ray SLX 250 2022 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 290 Sundancer 2006 measures 31,0 feet overall (2006), giving it roughly 5,4 additional feet of deck space compared to the Sea Ray SLX 250 2022 at 25,6 feet (2022). Weight tells a clearer story for trailering families: the Sea Ray SLX 250 2022 tips the scales at 5 800 lbs — 4 875 lbs less than the Sea Ray 290 Sundancer 2006 at 925 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 — 298 hp for the Sea Ray 290 Sundancer 2006 and 300 hp for the Sea Ray SLX 250 2022. 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 290 Sundancer 2006 carries 125 gallons versus 75 gallons in the Sea Ray SLX 250 2022. 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 290 Sundancer 2006 is rated for 9 passengers, while the Sea Ray SLX 250 2022 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Sea Ray 290 Sundancer 2006 could be the deciding factor.
