The AB Inflatables 15 VST 2010 vs AB-Inflatables Nautilus 12 DLX 2019 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 15 VST 2010 at 15,0 ft versus AB-Inflatables Nautilus 12 DLX 2019 at 12,0 ft. Weight tells a clearer story for trailering families: the AB-Inflatables Nautilus 12 DLX 2019 tips the scales at 515 lbs — 458 lbs less 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 VST 2010 and 40 hp for the AB-Inflatables Nautilus 12 DLX 2019. 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 15 VST 2010 carries 24 gallons versus 13 gallons in the AB-Inflatables Nautilus 12 DLX 2019. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The AB Inflatables 15 VST 2010 is rated for 9 passengers, while the AB-Inflatables Nautilus 12 DLX 2019 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 15 VST 2010 could be the deciding factor.
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 13 lbs per hp for the AB-Inflatables Nautilus 12 DLX 2019. 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 Nautilus 12 DLX 2019 is trailerable — a genuine lifestyle advantage at this size. The AB Inflatables 15 VST 2010 isn't listed as trailerable, which may mean a permanent berth or mooring is required.
Bottom line: Choose the AB Inflatables 15 VST 2010 if your priority is putting more people on the water — it handles 9 passengers and at 15,0 ft it has the deck room to back that rating up comfortably. The AB-Inflatables Nautilus 12 DLX 2019 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 3 that costs less to run day-to-day.
