When two boats share the same hull type — in this case both the AB Inflatables 11 AL 2013 and the AB Inflatables 19 DLX 2013 are inflatable rigid designs with aluminum construction — 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?

Size is the most obvious dividing line here. The AB Inflatables 19 DLX 2013 measures 19,0 feet overall (2013), giving it roughly 7,4 additional feet of deck space compared to the AB Inflatables 11 AL 2013 at 11,6 feet (2013). Weight tells a clearer story for trailering families: the AB Inflatables 19 DLX 2013 tips the scales at 6 502 lbs — 6 489 lbs less than the AB Inflatables 11 AL 2013 at 13 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 220 hp, the AB Inflatables 19 DLX 2013 has a 200-hp advantage over the AB Inflatables 11 AL 2013's 20-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The AB Inflatables 11 AL 2013 is rated for 6 passengers, while the AB Inflatables 19 DLX 2013 caps at 1. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the AB Inflatables 11 AL 2013 could be the deciding factor.
