When two boats share the same hull type — in this case both the AB Inflatables 12 DLX 2011 and the AB Inflatables A 13 2012 are inflatable rigid designs with fiberglass 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?

On paper these two are close siblings in the size department — AB Inflatables 12 DLX 2011 at 12,3 ft versus AB Inflatables A 13 2012 at 13,0 ft. Weight tells a clearer story for trailering families: the AB Inflatables 12 DLX 2011 tips the scales at 515 lbs — 261 lbs more than the AB Inflatables A 13 2012 at 254 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.

Both boats share a closely matched power ceiling — 30 hp for the AB Inflatables 12 DLX 2011 and 25 hp for the AB Inflatables A 13 2012. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup.

For family outings this is probably the sharpest distinction between the two. The AB Inflatables A 13 2012 is rated for 7 passengers, while the AB Inflatables 12 DLX 2011 caps at 6. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the AB Inflatables A 13 2012 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The AB Inflatables A 13 2012 comes in at 10 lbs per hp versus 17 lbs per hp for the AB Inflatables 12 DLX 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.
