When two boats share the same hull type — in this case both the AB Inflatables 15 DLX 2011 and the AB Inflatables 15 VST 2010 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 2011 at 15,0 ft versus AB Inflatables 15 VST 2010 at 15,0 ft. Weight tells a clearer story for trailering families: the AB Inflatables 15 DLX 2011 tips the scales at 739 lbs — 682 lbs more than the AB Inflatables 15 VST 2010 at 57 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 — 60 hp for the AB Inflatables 15 DLX 2011 and 60 hp for the AB Inflatables 15 VST 2010. 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. 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 VST 2010 comes in at 1 lbs per hp versus 12 lbs per hp for the AB Inflatables 15 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.
