The AB-Inflatables Alumina 11 ALX 2013 vs AB-Inflatables Ventus 9 VL 2015 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
On paper these two are close siblings in the size department — AB-Inflatables Alumina 11 ALX 2013 at 11,6 ft versus AB-Inflatables Ventus 9 VL 2015 at 9,6 ft.

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 — 25 hp for the AB-Inflatables Alumina 11 ALX 2013 and 10 hp for the AB-Inflatables Ventus 9 VL 2015. 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 Alumina 11 ALX 2013 is rated for 3 passengers, while the AB-Inflatables Ventus 9 VL 2015 caps at 2.

At this size, power-to-weight ratio matters more than outright horsepower. The AB-Inflatables Ventus 9 VL 2015 comes in at 11 lbs per hp versus 11 lbs per hp for the AB-Inflatables Alumina 11 ALX 2013. 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.
