The Xpress Bayou 16 2012 is a flat-bottom design and the Xpress X19SS 2010 is a modified-V design, so you're likely deciding between two noticeably 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 Bayou 16 2012 at 16,0 ft versus Xpress X19SS 2010 at 19,0 ft. Weight tells a clearer story for trailering families: the Xpress X19SS 2010 tips the scales at 1 390 lbs - 709 lbs less than the Xpress Bayou 16 2012 at 681 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 200 hp, the Xpress X19SS 2010 has a 160-hp advantage over the Xpress Bayou 16 2012'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 X19SS 2010 at 19,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The Xpress Bayou 16 2012 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.
