Matching a modified vee Xpress H18SS 2010 against a flat Xpress Tunnel - 1756T 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 H18SS 2010 at 18,0 ft versus Xpress Tunnel - 1756T 2008 at 17,0 ft. Weight tells a clearer story for trailering families: the Xpress H18SS 2010 tips the scales at 129 lbs — 124 lbs more than the Xpress Tunnel - 1756T 2008 at 5 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 150 hp, the Xpress H18SS 2010 has a 110-hp advantage over the Xpress Tunnel - 1756T 2008's 40-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
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 Tunnel - 1756T 2008 comes in at 0 lbs per hp versus 1 lbs per hp for the Xpress H18SS 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 H18SS 2010 and its 150-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Xpress Tunnel - 1756T 2008 with its 40-hp rating is the more economical daily driver.
