The Xpress DVX Series - DVX175 2008 is a deep-V design and the Xpress HD18SCA 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 DVX Series - DVX175 2008 at 17,0 ft versus Xpress HD18SCA 2011 at 18,0 ft. At 1 060 lbs and 1 155 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.

Both boats share a closely matched power ceiling - 115 hp for the Xpress DVX Series - DVX175 2008 and 115 hp for the Xpress HD18SCA 2011. 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.

Both boats are rated for 5 passengers - a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.

At this size, power-to-weight ratio matters more than outright horsepower. The Xpress DVX Series - DVX175 2008 comes in at 9 lbs per hp versus 10 lbs per hp for the Xpress HD18SCA 2011. The lower the ratio the more explosive the acceleration - meaningful on a short RIB where bursts of speed, quick planing, and agility in surf or tight waterways define the experience.
