Matching a flat Xpress 1650D 2011 against a modified vee Xpress H18SS 2010 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 1650D 2011 at 16,0 ft versus Xpress H18SS 2010 at 18,0 ft. At 41 lbs and 129 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.
The power gap is worth calling out. Rated to 150 hp, the Xpress H18SS 2010 has a 110-hp advantage over the Xpress 1650D 2011'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 H18SS 2010 comes in at 1 lbs per hp versus 1 lbs per hp for the Xpress 1650D 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 H18SS 2010 and its 150-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the Xpress 1650D 2011 with its 40-hp rating is the more economical daily driver.
