The Xpress 1650D 2011 vs Xpress HD17DB 2006 comparison sits squarely in the category of decisions where specs alone won't tell the whole story: intended use, storage, and long-term ownership costs all factor in.
On paper these two are close siblings in the size department - Xpress 1650D 2011 at 16,0 ft versus Xpress HD17DB 2006 at 17,0 ft. Weight tells a clearer story for trailering families: the Xpress HD17DB 2006 tips the scales at 887 lbs - 477 lbs less than the Xpress 1650D 2011 at 410 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 90 hp, the Xpress HD17DB 2006 has a 50-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 HD17DB 2006 comes in at 10 lbs per hp versus 10 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 HD17DB 2006 and its 90-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.
