The Xpress DVX195 2011 is a deep-V design and the Xpress X21 2011 is a modified-V design, so you're likely deciding between two noticeably different on-water experiences. Hull type shapes everything from ride quality and fuel burn to dock handling and resale trajectory.
On paper these two are close siblings in the size department - Xpress DVX195 2011 at 19,5 ft versus Xpress X21 2011 at 21,3 ft. At 1 673 lbs and 1 580 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.
The power gap is worth calling out. Rated to 250 hp, the Xpress X21 2011 has a 25-hp advantage over the Xpress DVX195 2011's 225-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Xpress X21 2011 carries 40 gallons versus 30 gallons in the Xpress DVX195 2011. 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 Xpress DVX195 2011 is rated for 6 passengers, while the Xpress X21 2011 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Xpress DVX195 2011 could be the deciding factor.
Bottom line: Choose the Xpress DVX195 2011 if your priority is putting more people on the water - it handles 6 passengers and at 19,5 ft it has the deck room to back that rating up comfortably. The Xpress X21 2011 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
