The AB Inflatables 15 DLX 2011 vs AB-Inflatables Nautilus 14 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 DLX 2011 at 15,0 ft versus AB-Inflatables Nautilus 14 DLX 2019 at 14,0 ft. At 739 lbs and 730 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.
Both boats share a closely matched power ceiling — 60 hp for the AB Inflatables 15 DLX 2011 and 50 hp for the AB-Inflatables Nautilus 14 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 DLX 2011 carries 26 gallons versus 15 gallons in the AB-Inflatables Nautilus 14 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 DLX 2011 is rated for 9 passengers, while the AB-Inflatables Nautilus 14 DLX 2019 caps at 4. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the AB Inflatables 15 DLX 2011 could be the deciding factor.
At this size, power-to-weight ratio matters more than outright horsepower. The AB Inflatables 15 DLX 2011 comes in at 12 lbs per hp versus 15 lbs per hp for the AB-Inflatables Nautilus 14 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 14 DLX 2019 is trailerable — a genuine lifestyle advantage at this size. The AB Inflatables 15 DLX 2011 isn't listed as trailerable, which may mean a permanent berth or mooring is required.
Bottom line: Choose the AB Inflatables 15 DLX 2011 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 14 DLX 2019 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 4 that costs less to run day-to-day.
