The Xpress DVX175 2011 is a deep-V design and the Xpress X19 2012 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 DVX175 2011 at 17,5 ft versus Xpress X19 2012 at 19,0 ft. Weight tells a clearer story for trailering families: the Xpress X19 2012 tips the scales at 1 390 lbs - 175 lbs less than the Xpress DVX175 2011 at 1 215 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 150 hp, the Xpress X19 2012 has a 35-hp advantage over the Xpress DVX175 2011's 115-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads - 30 gal and 30 gal - so range won't be a tiebreaker here.
For family outings this is probably the sharpest distinction between the two. The Xpress DVX175 2011 is rated for 5 passengers, while the Xpress X19 2012 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Xpress DVX175 2011 could be the deciding factor.
Bottom line: Choose the Xpress DVX175 2011 if your priority is putting more people on the water - it handles 5 passengers and at 17,5 ft it has the deck room to back that rating up comfortably. The Xpress X19 2012 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
