The AB Inflatables 8 VS 2011 vs AB-Inflatables Alumina 13 ALX 2017 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.

Size is the most obvious dividing line here. The AB-Inflatables Alumina 13 ALX 2017 measures 13,0 feet overall (2017), giving it roughly 4,5 additional feet of deck space compared to the AB Inflatables 8 VS 2011 at 8,5 feet (2011). Weight tells a clearer story for trailering families: the AB-Inflatables Alumina 13 ALX 2017 tips the scales at 386 lbs — 261 lbs less than the AB Inflatables 8 VS 2011 at 125 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.

The power gap is worth calling out. Rated to 30 hp, the AB-Inflatables Alumina 13 ALX 2017 has a 22-hp advantage over the AB Inflatables 8 VS 2011's 8-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load.

For family outings this is probably the sharpest distinction between the two. The AB Inflatables 8 VS 2011 is rated for 4 passengers, while the AB-Inflatables Alumina 13 ALX 2017 caps at 3. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the AB Inflatables 8 VS 2011 could be the deciding factor.

At this size, power-to-weight ratio matters more than outright horsepower. The AB-Inflatables Alumina 13 ALX 2017 comes in at 13 lbs per hp versus 16 lbs per hp for the AB Inflatables 8 VS 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.

The AB-Inflatables Alumina 13 ALX 2017 is trailerable — a genuine lifestyle advantage at this size. The AB Inflatables 8 VS 2011 isn't listed as trailerable, which may mean a permanent berth or mooring is required.
