When two boats share the same hull type — in this case both the AB Inflatables 15 DLX 2013 and the AB Inflatables F 15 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 15 DLX 2013 at 15,0 ft versus AB Inflatables F 15 2012 at 15,0 ft. At 682 lbs and 627 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The power gap is worth calling out. Rated to 75 hp, the AB Inflatables 15 DLX 2013 has a 25-hp advantage over the AB Inflatables F 15 2012's 50-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 26 gal and 24 gal — so range won't be a tiebreaker here.

Both boats are rated for 9 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.

At this size, power-to-weight ratio matters more than outright horsepower. The AB Inflatables 15 DLX 2013 comes in at 9 lbs per hp versus 13 lbs per hp for the AB Inflatables F 15 2012. 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.
