The AB-Inflatables Nautilus 19 DLX 2019 vs AB-Inflatables Nautilus 19 DLX I-O 2014 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 Nautilus 19 DLX 2019 at 19,0 ft versus AB-Inflatables Nautilus 19 DLX I-O 2014 at 19,0 ft. Weight tells a clearer story for trailering families: the AB-Inflatables Nautilus 19 DLX 2019 tips the scales at 1 639 lbs — 488 lbs more than the AB-Inflatables Nautilus 19 DLX I-O 2014 at 1 151 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 150 hp, the AB-Inflatables Nautilus 19 DLX I-O 2014 has a 35-hp advantage over the AB-Inflatables Nautilus 19 DLX 2019's 115-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Both carry nearly identical fuel loads — 67 gal and 67 gal — so range won't be a tiebreaker here.
Both boats are rated for 5 passengers — a good fit for a family of four or five plus guests. Comfort at capacity is another matter; the longer hull typically means more seat options and better weight distribution.
Bottom line: Performance buyers should lean toward the AB-Inflatables Nautilus 19 DLX I-O 2014 and its 150-hp ceiling. If fuel economy and quieter running matter more than top-end speed, the AB-Inflatables Nautilus 19 DLX 2019 with its 115-hp rating is the more economical daily driver.
