The Xpress DVX165 2011 is a deep-V design and the Xpress H18 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 DVX165 2011 at 16,5 ft versus Xpress H18 2012 at 18,0 ft. Weight tells a clearer story for trailering families: the Xpress H18 2012 tips the scales at 1 187 lbs - 127 lbs less than the Xpress DVX165 2011 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.
The power gap is worth calling out. Rated to 115 hp, the Xpress H18 2012 has a 25-hp advantage over the Xpress DVX165 2011's 90-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Xpress H18 2012 carries 30 gallons versus 24 gallons in the Xpress DVX165 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
Both boats are rated for 4 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 H18 2012 comes in at 10 lbs per hp versus 12 lbs per hp for the Xpress DVX165 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.
Bottom line: Performance buyers should lean toward the Xpress H18 2012 and its 115-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Xpress DVX165 2011 with its 90-hp rating is the more economical daily driver.
