The Xpress AWD18 2013 is a flat-bottom design and the Xpress XP18 2010 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 AWD18 2013 at 18,0 ft versus Xpress XP18 2010 at 18,0 ft. Weight tells a clearer story for trailering families: the Xpress XP18 2010 tips the scales at 1 045 lbs - 295 lbs less than the Xpress AWD18 2013 at 750 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 - 70 hp for the Xpress AWD18 2013 and 90 hp for the Xpress XP18 2010. 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 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 AWD18 2013 comes in at 11 lbs per hp versus 12 lbs per hp for the Xpress XP18 2010. 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 XP18 2010 and its 90-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Xpress AWD18 2013 with its 70-hp rating is the more economical daily driver.
