The Sea Ray 250 Select EX 2008 vs Sea Ray Sundeck 290 2017 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 Sundeck 290 2017 measures 29,2 feet overall (2017), giving it roughly 3,2 additional feet of deck space compared to the Sea Ray 250 Select EX 2008 at 26,0 feet (2008). Weight tells a clearer story for trailering families: the Sea Ray Sundeck 290 2017 tips the scales at 6 471 lbs — 1 079 lbs less than the Sea Ray 250 Select EX 2008 at 5 392 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 — 375 hp for the Sea Ray 250 Select EX 2008 and 380 hp for the Sea Ray Sundeck 290 2017. 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 Sundeck 290 2017 carries 85 gallons versus 75 gallons in the Sea Ray 250 Select EX 2008. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 8 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
