The Sea Ray 290 Select EX 2008 vs Sea Ray 320 Sundancer 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 320 Sundancer 2006 measures 35,0 feet overall (2006), giving it roughly 6,0 additional feet of deck space compared to the Sea Ray 290 Select EX 2008 at 29,0 feet (2008). At 77 lbs and 138 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

Both boats share a closely matched power ceiling — 375 hp for the Sea Ray 290 Select EX 2008 and 375 hp for the Sea Ray 320 Sundancer 2006. 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 Select EX 2008 carries 13 gallons versus 2 gallons in the Sea Ray 320 Sundancer 2006. 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 Select EX 2008 is rated for 12 passengers, while the Sea Ray 320 Sundancer 2006 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 290 Select EX 2008 could be the deciding factor.
