The AB-Inflatables Alumina 15 ALX 2014 vs AB-Inflatables Lammina 9 UL 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.
Size is the most obvious dividing line here. The AB-Inflatables Alumina 15 ALX 2014 measures 15,0 feet overall (2014), giving it roughly 5,9 additional feet of deck space compared to the AB-Inflatables Lammina 9 UL 2015 at 9,1 feet (2015). Weight tells a clearer story for trailering families: the AB-Inflatables Alumina 15 ALX 2014 tips the scales at 481 lbs — 397 lbs more than the AB-Inflatables Lammina 9 UL 2015 at 84 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 50 hp, the AB-Inflatables Alumina 15 ALX 2014 has a 40-hp advantage over the AB-Inflatables Lammina 9 UL 2015's 10-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 Alumina 15 ALX 2014 is rated for 4 passengers, while the AB-Inflatables Lammina 9 UL 2015 caps at 2. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the AB-Inflatables Alumina 15 ALX 2014 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The AB-Inflatables Lammina 9 UL 2015 comes in at 8 lbs per hp versus 10 lbs per hp for the AB-Inflatables Alumina 15 ALX 2014. 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.
Both the AB-Inflatables Alumina 15 ALX 2014 and AB-Inflatables Lammina 9 UL 2015 are trailerable, which is a big part of the appeal at this size. You can store either at home, hitch up on a whim, and launch wherever the water looks good.
Bottom line: Choose the AB-Inflatables Alumina 15 ALX 2014 if your priority is putting more people on the water — it handles 4 passengers and at 15,0 ft it has the deck room to back that rating up comfortably. The AB-Inflatables Lammina 9 UL 2015 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 2 that costs less to run day-to-day.
