The AB Inflatables 12 DLX 2011 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 12 DLX 2011 at 12,3 ft versus AB-Inflatables Nautilus 12 DLX 2019 at 12,0 ft. At 515 lbs and 515 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 — 30 hp for the AB Inflatables 12 DLX 2011 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. Both carry nearly identical fuel loads — 11 gal and 13 gal — so range won't be a tiebreaker here.
