When two boats share the same hull type — in this case both the AB Inflatables 13 DLX 2009 and the AB Inflatables 13 VST 2011 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 13 DLX 2009 at 13,2 ft versus AB Inflatables 13 VST 2011 at 13,0 ft. Weight tells a clearer story for trailering families: the AB Inflatables 13 DLX 2009 tips the scales at 589 lbs — 112 lbs more than the AB Inflatables 13 VST 2011 at 477 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 — 40 hp for the AB Inflatables 13 DLX 2009 and 40 hp for the AB Inflatables 13 VST 2011. 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. Fuel capacity breaks the other way: the AB Inflatables 13 DLX 2009 carries 18 gallons versus 15 gallons in the AB Inflatables 13 VST 2011. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.

Both boats are rated for 7 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 13 VST 2011 comes in at 12 lbs per hp versus 15 lbs per hp for the AB Inflatables 13 DLX 2009. 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.
