The Xpress DVX 175 2013 is a deep-V design and the Xpress HD Bay Series - HD22Bay 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.
Size is the most obvious dividing line here. The Xpress HD Bay Series - HD22Bay 2008 measures 22,0 feet overall (2008), giving it roughly 4,5 additional feet of deck space compared to the Xpress DVX 175 2013 at 17,5 feet (2013). At 1 215 lbs and 1 219 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 150 hp, the Xpress HD Bay Series - HD22Bay 2008 has a 35-hp advantage over the Xpress DVX 175 2013's 115-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 HD Bay Series - HD22Bay 2008 is rated for 6 passengers, while the Xpress DVX 175 2013 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Xpress HD Bay Series - HD22Bay 2008 could be the deciding factor.
Bottom line: Choose the Xpress HD Bay Series - HD22Bay 2008 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 175 2013 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 5 that costs less to run day-to-day.
