The Xpress DVX195 2009 is a deep-V design and the Xpress H51 2008 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 2009 at 19,5 ft versus Xpress H51 2008 at 17,0 ft. Weight tells a clearer story for trailering families: the Xpress DVX195 2009 tips the scales at 1 673 lbs - 768 lbs more than the Xpress H51 2008 at 905 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 225 hp, the Xpress DVX195 2009 has a 135-hp advantage over the Xpress H51 2008's 90-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
For family outings this is probably the sharpest distinction between the two. The Xpress DVX195 2009 is rated for 6 passengers, while the Xpress H51 2008 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 2009 could be the deciding factor.
Bottom line: Choose the Xpress DVX195 2009 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 H51 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
