The Xpress DVX Series - DVX175 2008 is a deep-V design and the Xpress HD22CF 2009 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.
Size is the most obvious dividing line here. The Xpress HD22CF 2009 measures 22,0 feet overall (2009), giving it roughly 5,0 additional feet of deck space compared to the Xpress DVX Series - DVX175 2008 at 17,0 feet (2008). Weight tells a clearer story for trailering families: the Xpress HD22CF 2009 tips the scales at 1 219 lbs - 159 lbs less than the Xpress DVX Series - DVX175 2008 at 1 060 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 - 115 hp for the Xpress DVX Series - DVX175 2008 and 130 hp for the Xpress HD22CF 2009. 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.
For family outings this is probably the sharpest distinction between the two. The Xpress HD22CF 2009 is rated for 6 passengers, while the Xpress DVX Series - DVX175 2008 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Xpress HD22CF 2009 could be the deciding factor.
Bottom line: Choose the Xpress HD22CF 2009 if your priority is putting more people on the water - it handles 6 passengers and at 22,0 ft it has the deck room to back that rating up comfortably. The Xpress DVX Series - DVX175 2008 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
