Matching a modified vee Sea Ray 210 Select 2009 against a semi displacement Sea Ray 390 Sundancer 2011 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 2011 measures 39,0 feet overall (2011), giving it roughly 18,0 additional feet of deck space compared to the Sea Ray 210 Select 2009 at 21,0 feet (2009). Weight tells a clearer story for trailering families: the Sea Ray 210 Select 2009 tips the scales at 408 lbs — 162 lbs more than the Sea Ray 390 Sundancer 2011 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.

The power gap is worth calling out. Rated to 425 hp, the Sea Ray 390 Sundancer 2011 has a 125-hp advantage over the Sea Ray 210 Select 2009's 300-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 390 Sundancer 2011 carries 25 gallons versus 4 gallons in the Sea Ray 210 Select 2009. 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 2011 is rated for 11 passengers, while the Sea Ray 210 Select 2009 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 2011 could be the deciding factor.
