Matching a flat Xpress 1650D 2011 against a modified vee Xpress X21 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.
Size is the most obvious dividing line here. The Xpress X21 2013 measures 21,3 feet overall (2013), giving it roughly 5,3 additional feet of deck space compared to the Xpress 1650D 2011 at 16,0 feet (2011). Weight tells a clearer story for trailering families: the Xpress X21 2013 tips the scales at 158 lbs — 117 lbs less than the Xpress 1650D 2011 at 41 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 X21 2013 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.
Bottom line: The Xpress X21 2013 at 21,3 ft is the right call if deck space, comfort, and entertaining are top of your list. The Xpress 1650D 2011 at 16,0 ft wins on trailering ease, likely lower purchase price, and simpler docking — a solid choice for a buyer who wants more boat for less money.
