The AB Inflatables 19 VST 2011 vs AB-Inflatables Nautilus 17 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 19 VST 2011 at 19,0 ft versus AB-Inflatables Nautilus 17 DLX 2019 at 17,0 ft. At 1 252 lbs and 1 250 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.

The power gap is worth calling out. Rated to 115 hp, the AB Inflatables 19 VST 2011 has a 25-hp advantage over the AB-Inflatables Nautilus 17 DLX 2019's 90-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the AB Inflatables 19 VST 2011 carries 45 gallons versus 33 gallons in the AB-Inflatables Nautilus 17 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 19 VST 2011 is rated for 15 passengers, while the AB-Inflatables Nautilus 17 DLX 2019 caps at 5. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the AB Inflatables 19 VST 2011 could be the deciding factor.
