Matching a flat Xpress AWD18 2013 against a modified vee Xpress H51 2008 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 H51 2008 at 17,0 ft. Weight tells a clearer story for trailering families: the Xpress H51 2008 tips the scales at 905 lbs — 830 lbs less than the Xpress AWD18 2013 at 75 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 H51 2008. 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 1 lbs per hp versus 10 lbs per hp for the Xpress H51 2008. 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.
