Matching a flat Xpress AWD18 2013 against a tunnel Xpress XP170 Jet 2013 means you're likely deciding between two genuinely 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 XP170 Jet 2013 at 17,0 ft. At 75 lbs and 92 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 — 70 hp for the Xpress AWD18 2013 and 90 hp for the Xpress XP170 Jet 2013. 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 XP170 Jet 2013 comes in at 1 lbs per hp versus 1 lbs per hp for the Xpress AWD18 2013. 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 XP170 Jet 2013 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.
