The Sea Ray 290 Select EX 2007 vs Sea Ray Sundancer 52 2006 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 52 2006 measures 52,0 feet overall (2006), giving it roughly 23,0 additional feet of deck space compared to the Sea Ray 290 Select EX 2007 at 29,0 feet (2007). Weight tells a clearer story for trailering families: the Sea Ray Sundancer 52 2006 tips the scales at 38 500 lbs — 38 423 lbs less than the Sea Ray 290 Select EX 2007 at 77 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 660 hp, the Sea Ray Sundancer 52 2006 has a 285-hp advantage over the Sea Ray 290 Select EX 2007's 375-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 52 2006 carries 56 gallons versus 13 gallons in the Sea Ray 290 Select EX 2007. 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 52 2006 is rated for 15 passengers, while the Sea Ray 290 Select EX 2007 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 52 2006 could be the deciding factor.
