Matching a modified vee Sea Ray 270 Select EX 2010 against a semi displacement Sea Ray 390 Sundancer 2010 means you're likely deciding between two genuinely different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.

Size is the most obvious dividing line here. The Sea Ray 390 Sundancer 2010 measures 39,0 feet overall (2010), giving it roughly 10,5 additional feet of deck space compared to the Sea Ray 270 Select EX 2010 at 28,5 feet (2010). Weight tells a clearer story for trailering families: the Sea Ray 270 Select EX 2010 tips the scales at 5 555 lbs — 5 309 lbs more than the Sea Ray 390 Sundancer 2010 at 246 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 — 425 hp for the Sea Ray 270 Select EX 2010 and 425 hp for the Sea Ray 390 Sundancer 2010. 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 270 Select EX 2010 carries 91 gallons versus 25 gallons in the Sea Ray 390 Sundancer 2010. 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 390 Sundancer 2010 is rated for 11 passengers, while the Sea Ray 270 Select EX 2010 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 390 Sundancer 2010 could be the deciding factor.
