The Sea Ray 290 Select EX 2007 vs Sea Ray 340 Sundancer 2007 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 340 Sundancer 2007 measures 37,0 feet overall (2007), giving it roughly 8,0 additional feet of deck space compared to the Sea Ray 290 Select EX 2007 at 29,0 feet (2007). At 77 lbs and 155 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 2007 and 375 hp for the Sea Ray 340 Sundancer 2007. 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 340 Sundancer 2007 carries 225 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 340 Sundancer 2007 is rated for 11 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 340 Sundancer 2007 could be the deciding factor.
