Both the AB Inflatables 16 AL - Superlight 2011 and the AB Inflatables F 19 Jet or Stern Drive 2012 are rigid inflatable designs, the first built in aluminium and the second in fibreglass, so the buying decision usually comes down to a handful of practical questions: how many people are you putting on the water, how far do you trailer, and what does your tow vehicle weigh?
On paper these two are close siblings in the size department - AB Inflatables 16 AL - Superlight 2011 at 16,0 ft versus AB Inflatables F 19 Jet or Stern Drive 2012 at 19,0 ft. Weight tells a clearer story for trailering families: the AB Inflatables F 19 Jet or Stern Drive 2012 tips the scales at 1 430 lbs - 1 082 lbs less than the AB Inflatables 16 AL - Superlight 2011 at 348 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 AB Inflatables F 19 Jet or Stern Drive 2012 has a 100-hp advantage over the AB Inflatables 16 AL - Superlight 2011's 50-hp ceiling - enough to notice on acceleration and at cruising speed, particularly with a full passenger load.
Both boats are rated for 10 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 AB Inflatables F 19 Jet or Stern Drive 2012 at 19,0 ft is the right call if deck space, comfort, and entertaining are top of your list. The AB Inflatables 16 AL - Superlight 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.
